As soon as warm weather and sunshine arrive in Southern Ontario, it’s time to head to the garden centre and pick up all the plants we’ve been dreaming about all winter long! May 24th is generally the date we look forward to — the unofficial marker when frosty mornings are behind us and the promise of summer is ahead. 

By now, cool-weather plants like cabbage, Brussels sprouts, peas, and lettuce should be well established in the vegetable garden. And for everything else, it’s go time!

TIP: Before you start planting, this is the ideal time to amend your soil. Top up your garden beds with fresh topsoil or enrich them with compost to improve soil health, add nutrients, and promote vigorous plant growth. Don’t forget to refresh the soil in your containers as well, with potting mix or compost.

Warm Weather Vegetables

When soil temperatures are consistently 60°F (15°C) or higher, it’s safe to plant all the warm-weather vegetable crops we’ve been waiting for! Plants that thrive in warmer weather include tomatoes, peppers, eggplants, cucumbers, zucchini and corn.

At Eising Garden Centre, you’ll find vegetables in 6-packs, 4” pots, trellised patio containers, patio bowls and hanging baskets - while supplies last, of course!

Herbs also love warm weather, and tender varieties like basil are safe to plant once all danger of frost has passed. Whether you plant herbs directly into the ground or create a potted herb garden near the kitchen door, they’ll add fresh flavour to your meals all season long. A container of herbs also makes a wonderful gift when visiting friends and family for a summer BBQ.

While you’re in the vegetable and herb aisle, keep an eye out for everbearing strawberries in planters and containers of tropical fruits like lemons, limes, and oranges.

Annual Flowers

Winter-weary flower beds can be revived almost instantly with a burst of colourful annuals! If you’re looking for an immediate impact and blooms that last all summer long, annual flowers are the answer.

Whether you plant them in beds, containers, window boxes, or hanging baskets — or choose from one of our gorgeous pre-planted options — just add water and fertilizer, and you’ll be rewarded with a vibrant display that keeps on giving.

Perennials

While perennials may not bloom all summer, many offer extended bloom periods, and by combining different varieties, you can create a succession of flowers that lasts for months. Perennials also provide essential greenery to anchor your garden and enhance the look of your flowering plants.

You can plant perennials from spring through fall, but getting them into the ground now gives them a strong start. From hostas and ornamental grasses to daisies and delphiniums, there’s a perennial for every style of garden — and the best part is, they’ll return each spring like dependable old friends.

Trees, Shrubs and Vines

Often called “the bones” of the garden, trees, shrubs, and climbing vines add essential structure, height, and seasonal interest. Planting them now allows you to design your garden layers thoughtfully, incorporating annuals and perennials around their base.

Spring is also the prime time to purchase and plant fruit trees and fruiting shrubs. At Eising, spring offers the best selection for starting your home orchard. Are you thinking of adding a few edible shrubs? Gooseberries, haskaps, hardy kiwi, rhubarb and raspberries are excellent choices.

Mulch

Okay, it’s not a plant, but this is a reminder to add mulch to your garden beds or containers. After planting, adding a layer of mulch to your garden beds or containers helps retain soil moisture, reduces transplant shock, and suppresses weeds. Even if a few weeds manage to sneak through, mulch makes them easier to pull.

Water Garden Plants

If you have a garden pond, spring is the perfect time to add water plants. Floating plants, such as water hyacinths and water lilies, help shade the pond’s surface, reducing algae blooms. Marginal or bog plants, such as water iris, papyrus, and cattails, also help keep the water healthy and clear by improving oxygen levels and providing habitats for beneficial wildlife.

Time to Grow!

May is one of the most anticipated and exciting months in the garden. Whether you’re dreaming of fresh vegetables, a lush landscape, or a colourful flower display, planting now sets the stage for a beautiful, bountiful season. Visit us at Eising Garden Centre to find everything you need — and let’s get growing!

How to Identify These Annoying Little Gnats

By Ava Green

Do you have tiny flies buzzing around your home and have no idea where they came from? Before you can get rid of them, you need to know what you're dealing with. Most people assume they're fruit flies, but there's a good chance they're not.

There are three common culprits: 

• Drain flies breed in moist drains. Keep drains closed when not in use.
• Fruit flies hover around overripe produce.
• Fungus gnats, the most commonly misidentified of the three, love the damp soil in your houseplants, and they're the ones most likely buzzing around the house.

Fungus Gnats are Probably Already in Your Home

Every time you bring a plant indoors,  whether it's brand new or returning after a summer outside, there's a very good chance it's carrying fungus gnat eggs in its soil. When you purchase bagged soil, it will often contain fungus gnat eggs as well. They're small, they're sneaky, and here's the most important thing to know: they multiply fast. Left unmanaged, a handful of gnats can turn into hundreds within weeks.

What Makes Fungus Gnats Thrive?

Fungus gnats love warm, moist conditions and organic material, like your potting soil. Adult gnats lay eggs in damp soil, which gives their larvae everything they need to develop.

The good news? Once you understand what they need to survive, stopping them is very easy and straightforward.

7 Proven Ways to Get Rid of Fungus Gnats 

1. Quarantine any new or returning plants for 4 weeks. This single step prevents gnats from spreading to your other houseplants while you treat the soil.

2. Use yellow sticky traps. These inexpensive traps attract and catch adult gnats before they can lay more eggs. Place one directly into the soil near your plant. Putting a sticky trap in a planter, whether it’s a new plant or one you’ve had a while, is also a good way to monitor whether or not you have pests in your plants.

3. Let the top inch of soil dry out completely between waterings. Fungus gnats need moist soil to lay their eggs. Deny them that, and you deny them a future. To test whether the soil has dried out, poke one of your fingers in it about an inch to check for moisture.

4. Cover the soil surface with coarse sand or vermiculite. A layer of sharp, gritty material on top of the soil is uninviting to egg-laying adult gnats. Make sure to use coarse sand, fine sand won't do the trick.

5. Switch to bottom watering. This is the best watering method for a number of reasons, including discouraging fungus gnats. Fill a tub or sink one-quarter full and set your pot in it for about 30 minutes allowing water to be absorbed into the soil via the drainage hole in the pot. When the soil and roots absorb water from below, it keeps the top layer of soil, where gnats want to lay their eggs, dry and uninviting. Make sure the water level covers no more than one-third of the pot, not the entire pot.

6. Try Mosquito Dunks (the secret weapon most gardeners don't know about). These contain BTI, a naturally occurring bacterium that is harmless to humans, pets, and plants, but lethal to fungus gnat larvae. Simply follow the package instructions and water your plants as normal. Water activates mosquito dunks.

7. Water with diluted hydrogen peroxide once a week. Mix one part 3% hydrogen peroxide with four parts water (so ¼ cup peroxide to 1 cup water). Apply this solution once a week for three weeks, and let the soil surface dry out between each application. It kills larvae on contact. Don't overdo it though.  Too much, too often can damage roots.

Don’t Forget Your Fruit Bowl: Try This Banana Trick

Fungus gnats aren't just plant pests, they're also drawn to fruit, especially bananas. The stem end of a bunch of bananas is a prime spot for gnat eggs. The fix is simple: as soon as you get home from the grocery store, rinse your bananas under lukewarm running water and give the stem a gentle scrub with a soft brush. It takes about a minute and can prevent a whole new infestation before it starts.

The Bottom Line

Fungus gnats feel impossible to eliminate because most people only address the adults they can see and not the larvae multiplying in damp soil. Use these tips in combination for the best results, and remember: even a fresh bag of potting soil can carry eggs, so treat new soil with BTI or a hydrogen peroxide solution before use.

Stick with it for a few weeks and your home and your plants will be gnat-free.

Usually, by the time February or March rolls around, I’m pretty tired of the health crazes like extreme diets and exercise plans I’ve been trying for the fifth year in a row. This year, let’s take a look at something that naturally supports our good health, both mental and physical. It’s time to stop and “smell the flowers,” so to speak.

Mental and Physical Health

Many gardeners already realize this, but studies are showing that simply seeing greenery can benefit our mental health. Whether it's a walk in the woods or a handful of houseplants, seeing green leaves makes a difference for humans! Research shows that it helps boost our mood and improve how we get along with people. Who doesn’t need a mood booster during cold, dark days? And getting along with people, well, the world just needs more of that, too, doesn’t it?

You may also already know that tending to plants reduces stress, but did you know that science is proving it? PubMed published a study stating:

"Interaction with indoor plants may reduce psychological and physiological stress by suppressing autonomic nervous system activity in young adults: a randomized crossover study."

This isn’t the common thinking about working outside in the garden increasing physical strength and stamina. It’s a study that examines our autonomic nervous system, the one responsible for automatic and essential bodily functions we don’t even think about, like breathing. The study compared participants performing two tasks: one on a computer and the other doing plant transplanting. The results suggest that interaction with plants indeed reduce stress without us even thinking about it! No task that requires willpower, just daily tending to plants like transplanting, watering, dusting, pruning, or turning the pots to get sun on the flipside.

So plants boost our mood, improve interactions with others and physically reduce our stress levels without us even trying. It’s no wonder we just feel better when we’re around plants.

Air Quality

Research also shows that indoor air pollution is often worse than outdoor air pollution. VOCs (Volatile Organic Compounds) from washing detergents, paint, furnishings, and building materials, as well as bacteria, fungal spores, and dust, negatively affect human health.

Fresh air can counter the impact of indoor pollutants, but often it’s too cold to open the windows in the middle of winter. When you can’t let fresh air into the house, indoor plants will help. We know that growing trees outdoors has a massive impact on air quality and the health of the planet, and inside our home, tropical plants contribute in the same way. The contribution of each type of plant varies, so having a variety is a very good idea.

What to Grow

Here’s a list of easy-to-grow, green indoor plants that Eising’s resident tropical plant expert, Courtney, and the UK’s Royal Horticultural Society (RHS) recommend:

Aglaonema ‘Silver Queen’ (Chinese evergreen ‘Silver Queen’)

Aspidistra elatior (common Aspidistra, Cast Iron plant)

Chamaedorea elegans (Parlour Palm)

Chamaedorea seifrizii (Bamboo Palm)

Chlorophytum comosum (Spider Plant)

Crassula ovata (syn. Crassula portulacea) (Jade plant, Jade tree)

Dracaena fragrans ‘Janet Craig’ (Dragon Plant)

Dieffenbachia ‘Tropic Snow’ (v) (Dumb Cane)

Dracaena marginata (v) (Madagascar dragon tree)

Epipremnum aureum and ‘Marble Queen’

Ferns - many types

Ficus elastica (Rubber tree, Rubber plant)

Hedera helix (English ivy, common ivy)

Howea forsteriana (Flat Palm, Kentia palm)

Rhapis excelsa (Bamboo Palm, Lady Palm)

Sansevieria (Snake Plant) - many types

Spathiphyllum sp. (Peace Lily)

Syngonium podophyllum (Nephthytis)

Zamioculcas zamiifolia (ZZ plant, fern arum)

Is there a downside to having houseplants? Yes, if you have small children or pets, be mindful of the plants that can be toxic if ingested (see resources listed below).

While many of us in Ontario focus on “nice” weather and getting outside to garden, it’s pretty clear that our indoor plants do much of the heavy lifting to improve our health through the cooler seasons. Even if you don’t have a “green thumb”, it’s worth giving tropical, indoor houseplants their well-deserved space in our homes, hospitals, offices, nursing homes, classrooms, restaurants…or any indoor space!

Adding Year-Round Interest to Your Garden

By Ava Green

Spring brings excitement and the hope of fresh beginnings, but also the harsh reality that our gardens can look a little…well…blah, in between seasons. Even when you have evergreens, well shaped trees, shrubs or perennials with “good bones” (strong framework or structure) a garden can look bare off season. This is when garden features and ornaments can really make a dramatic difference!

Create Year-Round Interest In Your Garden

Do you have a spot in the garden where plants struggle to grow? Or an area where you feel like your garden is missing something? 

Items like benches, patios, ornamental urns, decorative fencing, statues, a pond, gazing balls, birdhouses and birdbaths add beauty and function in every season. In Southern Ontario’s long shoulder seasons (early spring, late fall, and the longest of all - winter) these permanent elements help to make your garden look inviting all year.

Why Every Garden Benefits from a Focal Point

A garden filled with colourful annuals and perennials can be stunning, but without a focal point, it can feel visually overwhelming. A garden focal point like a bench, statement urn, a piece of statuary, or a water feature draws your attention, and creates a sense of purpose.

Focal points guide movement through the garden and help tell a story, leading visitors toward a destination. While naturalized gardens and wildflower areas don’t always require structure, for gardeners who prefer a more organized look, incorporating a focal point can create a sense of order and transform your space.

Add Contrast With Texture and Shape

Many gardeners naturally gravitate toward favourite plant forms. Tall, spiky perennials like coneflowers, salvia, and Black-eyed Susan are popular in Ontario gardens but they can feel repetitive when planted together.

Introducing contrast changes everything. A round birdbath nestled among upright perennials adds softness and contrast making it more visually interesting. In shady gardens dominated by hostas, a tall iron obelisk or trellis creates height and drama. Mixing plant textures with garden features like lighting instantly elevates beds and borders.

Express Your Personality!

Gardening is a creative process, and experimentation is part of the joy. Moving plants to find the right light or shelter often leads to surprising combinations and successes. Garden features allow you to express that creativity even further.

Statuary, ornaments, and structures, whether handcrafted or purchased, add personality and meaning. From whimsical accents to bold architectural elements, these features bring height, structure, and style to your garden in ways plants alone can’t.

More Than Just Flowers

Flowers bloom and fade with the seasons here in Southern Ontario. Garden features provide continuity, offering year-round interest, structure, and charm. With just a few additional elements, your garden can look beautiful in every season, not just when it’s in bloom.

Got cabin fever? Perhaps you’re going a little stir crazy looking out the window and seeing the drab, limited pallete in your seemingly lifeless outdoor space. It’s important to embrace this time of year as the composting and cleansing part of Earth’s cycle before spring’s renewal – but that doesn’t mean we should be trapped inside forever. Here’s a winter/early spring list of activities, divided by indoor (Part 1) and outdoor (Part 2), for the gardener and yard keeper.

☝️ First, let’s quickly note the important activity happening under the snow – and how your actions now will affect the summer garden!

What's Going on Outside When We Aren't Paying Attention?

Before heading out to attend to these jobs have a look at the ground beneath you.

   If it is frozen hard you are good to go but avoid treading on the crowns of perennials.

   If it has been warm and sunny and the soil is warm and dry, consider laying down a few planks to walk on.

   If the soil is soggy then postpone those tasks until it has dried. What we are trying to protect is not your shoes but the soil itself.

   Ideally, soil is comprised of 50% solid materials such as minerals and organic matter in various stages of decomposition, and 50% open air space. Water from rain or melting snow enters the soil, displacing the air. Wet soil is easier to squish down and that process is called compaction.

   While walking on wet soil would not seem to have much effect, it occurs within the depth where annuals, perennials and lawn grasses have their roots. Compaction makes it harder for roots to grow through the soil. Roots can grow stronger to push aside the soil particles, but tougher roots are less effective at drawing in nutrients and moisture. Removing air spaces makes it more difficult for water to percolate down so compacted soils remain wetter. Plants don’t grow as well and are more prone to insect damage.

   The freeze/thaw cycles of fall, spring, and winter heave the soil relieving compaction and aerating the soil; a good way to start the growing season. Preventing further damage to the soil is relatively simple. Stay off it when it’s wet. Later, consider using pavers or pathways in heavily travelled areas of the lawn. Aerate the lawn with a machine that removes small plugs of soil and redistributes them over the surface. In beds and borders, add compost and use a thick mulch layer to absorb some of the pressure.

 And stay off it when it’s wet.

With this in mind, we can appreciate Earth’s renewal capabilities, as well as prevent destroying our yards and gardens!

Part 1: Activities for When it’s too Cold and the Soil isn’t Ready Yet

Yup, it’s bleak out there. It’s time we make that herbal tea and turn our attention to creating a lively, green indoor environment, even if just to get us through the winter. Here’s a to-do list for trapped gardeners and plant enthusiasts to make the most of our wintry sentence.

Indoors: Get Inspired!

• Expand your knowledge: There’s an endless plethora of botanical media at our fingertips, use this down time to learn more!

• Sustainable winter crafts: Why buy décor and gifts when you can make them from materials found outside? Perhaps you dried flowers or found some interesting seed pods – time to display them, and perhaps, eventually compost them.

• Visit botanical gardens: Ely’s boyfriend took her to the Royal Botanical Gardens as a birthday gift last year! Botanical gardens are a great way to experience interesting plants being preserved in a welcoming environment that differ from the dreary winter outside.

• Get floral: Try buying flowers and displaying your own arrangements! Colour is something we sometimes lack in the wintry months, and this is a good way to introduce it impermanently.

Indoors: Thinking Ahead!

• Use this winter down time to plan the next garden season - find more here on garden planning. 

• Use a garden journal to assist your garden planning - see here inspo for garden journaling. 

• Consider planning companion plants - see more here on companion planting.

• Go pot shopping – your local greenhouses and ceramic shops would love your support in the winter.

Indoors: New Beginnings!

• Bulb forcing and small science experiments: Flowering bulbs like amaryllis (more on amaryllis here) aren’t just a holiday splendor! Now is also the time to create cuttings to share with friends.

• Invest in winter fruiting botanicals like indoor fruit trees. Small, potted citrus by the window don’t only liven up the place but offer nutritious treats in the winter. Consider a calamondin!

• Microgreens - see our blog about it! When it’s too early to start seedlings that will go in the ground, you can still garden right on your kitchen counter.

• In late winter, start seedlings: but make sure you don't do so too early! Untimely seedlings can be too leggy before it's time to plant them outside - learn about hardening off seedlings here.

Part 2: When the Soil IS Ready!

Suit up!

Outdoors: Don’t Fall Behind!

• Appropriate seasonal décor: It goes without saying stringing lights and ornaments everywhere is good for the spirits in these dreary months… however 😬… come February, they seem to lose their vigor. Taking the décor down in preparation for new exciting things to come is also good for the soul! Remember to recycle your Christmas tree (see how here)!
• Turn your compost! Perhaps you’ve faithfully continued to add to your compost all year – your garden thanks you! On a warm day, remember to turn it and aerate it so it’s ready for spring.
• Cover all your bases: Make sure to prevent rodents from damaging your tree bases by wrapping them well above the anticipated snow level – so rodents can’t chew your unprotected trees with the helpful elevation of snow!

Outdoors: Get Inspired!

• Go for nature walks: if you can safely go for a walk, hit the trails or stroll around your neighbourhood! A slow-paced change of scenery will help to fight your cabin fever, keep you active, and help you gather inspiration from the natural world.

• Visit your local maple syrup producers for tours.

• Don’t forget our critters: Provide winter homage and appropriate food for our nonmigratory friends (i.e., hutches and feeders) outside windows where pets can observe nature too!

Outdoors: Thinking Ahead!

• Winter weeding: Some tough varieties of plants have evolved to use other plants’ winter dormancy to their advantage, tugging them out now will ensure that you and all the wanted plants in your garden have a fair start this spring.
• Manage snow piling: Heaped snow piling can kill plants including lawn, as well as introduce gravel and debris to areas where gravel is not wanted. Make sure your snow piles aren’t suppressing anything you’d like to live this summer.
• Early spring: Perhaps ice storms and plows have done a number on your trees and shrubs - prune broken branches to prevent pests and disease from entering your plants.
• Litter control: pick up the debris revealed by melting snow so it doesn’t venture farther into natural habitats or tempt wild animals to hurt themselves.  

Outdoors: Start Something New!

• Cold hardy crops in cold frames: Cold frames are doable! Use recycled materials - Victory gardens often used car windshields and old windows – to construct in-ground beds facing the sun (southwards) for passive solar heating.

• Winter sowing: Find more on winter sowing here.

We hope these suggestions help you stay green this spring and winter! For more gardening activities, see our other blogs here. We hope to see you this spring (March 5^th, 2026) at Eising Greenhouses and Garden Centre! 🌱❄️

This is a question we hear daily during the spring, summer and, especially, the fall. Unfortunately, many homeowners do not see any adverse changes occurring in their trees until they look dead, or nearly so.

You Might Not Need to Panic Yet

The discolouration and dropping of evergreen needles are a natural phenomenon and the main cause of needle loss in the wild. Evergreen needles, as the name implies, survive for a lengthy period, and in fact usually have a life span of five to seven years on healthy trees, however, they must be shed. The needles first start to die in the central and lower part of the tree, and this change progresses upward over time. You will see spruce trees naturally lose needles as they get older.

   Age is an important factor here in causing needle loss and branch death, however, in landscape plantings of coniferous evergreen trees, pests and disease are likely the major cause of needle loss and dying branches. If there is a sudden fall of a very large number of brown needles and leaves, this signals to us that there is something drastically wrong!

   This can happen as early as a year or two after a tree is planted. This is especially true in Haldimand and Eastern Norfolk County where heavy clay soils predominate. Spruce trees, for example, do not grow well on clay soils.

When You DO Need to Worry

Here are some of the more common problems, apart from natural aging that afflict spruce trees, the probable causes and ways of treating the problem.

☝️Unfortunately, these majestic trees, the most popular evergreen planted on our residential properties, incur many other pest and disease problems not dealt with here.

Symptom: Rusty brown needles that eventually fall.

Likely causes:

1. Internal fungus disease (called Cytospora or white blister canker). This creates cracks in the bark causing resin to drip and leave grey-white dripping streaks on the bark. The fungus also causes open wounds or blisters on tops of branches. These wounds can be greyish white or greyish blue in colour, eventually turning brown and black.

2. Feeding by spider mites which leave fine, poorly formed webs in the needles, especially near the ends of the twigs.

Best treatments:

1. Properly aerate and fertilize tree out to a distance of half its height in all directions, where possible.

2. Pressure wash thoroughly once a month with water only, all needles and branches as high as possible on the tree. Water pressure dislodges spider mites.

Symptom: Chewed up ends of twigs in June.

Likely cause:

Spruce bud worms which develop in the needle cluster that arises from a bud.

Best treatment:

Spray the biological pesticide, BTK (eg. Dipel), onto the entire tree when feeding is first noticed in early spring, to kill the young caterpillars.

Symptom: Black sooty mold covering twigs and needles.

Likely causes:

1. Spruce bud scales, ball-shaped insects, initially light brown in colour but eventually turning black. Often two to five scale balls cluster in one location on the twig; honey dew excretions from scales become infected with sooty mold.

2. An overhanging shade tree such as oak, maple or elm may have heavily infested leaves with aphids whose honey dew secretions become infected with sooty mold.

Best treatment:

1. Pressure wash tree using water only to dislodge young scales (called nymphs) in May and early June while they are in the crawling stage. Scale nymphs fall to the ground where they cease to be a threat to the tree.

2. Spray shade tree in early spring with insecticidal soap to control aphids. The problems of other coniferous evergreens such as pines, firs, cedars and junipers can usually be treated with correct diagnosis, though some diseases are lethal.

We hope these help you troubleshoot common issues often found in evergreen trees! For more information - and evergreens – visit Eising Greenhouse and Garden Centre! 🌲

As plant people, we’ve all experienced that moment when we realize the novelty phase of that plant we brought home from the garden centre has worn off. The plant isn’t standing quite as tall, the flowers aren’t as bold, and the leaves are unravelling smaller or not at all. What is this magic they perform in the greenhouse? Perhaps you’ve provided sufficient lighting and adequate watering; there’s just one thing that is often overlooked because dirt is dirt, isn’t it?

  97% percent of plant tissue is made up of carbon, hydrogen, and oxygen pulled from the air and water, the remaining 3% is comprised of 16 other elements taken up from the soil. The quality of soil then is crucial to your plant’s health. Whether your plants are in pots or in ground, each soil type you could provide your plant offers something unique and may lack in another.

*Clay particles are even smaller than silt particles.

Resist the Urge to Slam Your Plant in Potting Soil

There’s bags and bags of rocks, sand, bark, manure, and moss on the shelves, yet the common buyer seems to always opt for potting mix. It’s fair; organic matter is usually great for plants and simple to use. However, most people don’t realize it’s merely an ingredient.

   Strictly using potting mix is like attempting to make a loaf of bread out of only flour. All those bags of other materials on the shelves are also components for a successful plant diet!

  Potting mix is a great base material, however, alone it presents risks of compacting, becoming waterlogged, can mold easily, and over time will become depleted of nutrients. Consider mixing the following ingredients into your pots, ground and raised beds to meet your plant’s required nutrients, pH level, and volume of moisture.

🖱️Use our Plant Finder to find some details on your plant! We try our best to keep this updated!

👍 Rule of Green Thumb: Plant roots can help you to determine the medium needed – thick, robust roots (i.e., yucca) typically enjoy chunkier materials, and smaller, delicate roots (i.e., begonias) enjoy finer materials.

Mulch and Bark Bites

• Mulch is the organic slow-release fertilizer, as it slowly decomposes, it lowers soil pH. However, may eventually compact soil once fully broken down.
• In the meantime, it creates shelves in the soil that create air pockets and prevent the soil from compacting. Mulch is a great short term medium for arid potted plants.
• If kept too wet, it can harbour fungus gnat larvae.
• Make sure when sourcing your mulch it doesn’t contain any black walnut.

🖱️ See more on mulching here. 

Sphagnum Peat Moss

• Peat moss is used to help retain moisture and lower pH in the soil given it is harvested from bogs.
• Retains nutrients very well.
• It is difficult to rehydrate once it loses moisture.

Coconut Coir

• Coco coir, much like peat moss is used to keep the soil moist and keep pH low, however it lasts longer and is possibly less invasive to harvest.

Sand

• Grains are relatively large and do not bind, allowing for excellent drainage depending on grade.
• Adds weight to top heavy plants.
• Has no ability to store minerals itself, however, pH can vary by its content of shells, minerals like silica, or fine organic matter.

Manure & Compost

• Source these organic by products locally and ensure they’re not too hot. These additions can significantly lower pH.
• Sheep manure is usually near free of weed seeds as sheep digest seeds better than cattle and horses!

Perlite

• Perlite is a volcanic byproduct (so it floats like pumice) that helps drainage in the soil and prevents compaction – vital in the case of starting seeds.
• If a rockier, well-draining medium is required for your plant, consider perlite.
• Perlite can expand holding trace amounts of water.
• Perlite has a neutral, slightly acidic pH.
• Make sure when sourcing perlite, that you are not being sold Styrofoam balls.

Vermiculite

• Vermiculite is a recycled mineral used similarly to perlite, and too has a neutral, slightly acidic pH.
• Expands with water content.
• Can contain amounts of potassium and magnesium (as well as good cation exchange capacity).
• Runs the potential risk of introducing asbestos into your soil.

Calcined Clay Materials

• Clay materials like recycled brick bits, pottery, or lecca are typically used for arid plants as it improves aeration and drainage.
• Can raise pH.
• Can retain some water.
• High cation exchange.
• Can also be used for starting robust cuttings when kept moist.  
• Probably not ideal for inground amendments.

Maintaining Your Plant’s Dietary Needs

Perhaps we’ve crafted the perfect soil type for your plant – your plant thanks you – but over time, we will end up in the same staling predicament. Why? Because with each thorough watering, we leech the soil of the provided nutrients. Best we use the plant-specific required fertilizer for your plant to prevent nutrient loss.

   Organic sources of fertilizer such as bonemeal, composts, and manures, along with the application of lime, will improve the physical condition of the soil in terms of water and element holding ability. Unfortunately, in many cases though, manures and lime alone cannot be depended upon to provide enough available nutrients in soils with low essential element reserves.

   Let’s talk about commercial fertilizers, which can help target your plant’s exact needs much like vitamins and supplements!

The Scoop on Fertilizers

Of the essential 16 elements your plant pulls from the soil, Nitrogen (N), Phosphorus (P), and Potassium (K) are the most critical for good plant growth. You’ll recognize the three numbers appearing on your commercial fertilizer labels known as the fertilizer analysis of the product, representing the percentage of each of the three "macronutrients" in the order of N, P & K.

Nitrogen (N) is necessary for green leafy or vegetative growth which is important in crops like corn, cabbage, and potatoes.

☝️ It is important to remember that you should not use a fertilizer which is high in nitrogen late in the summer on your perennials, as it may cause a boost of growth which will only freeze as the cold weather sets in. Also, too much nitrogen in the analysis could cause too much lush, leafy growth thus inhibiting the desired flowering aspect of a plant species.

Phosphorus (P) promotes the development of flowers, fruit and roots. Crops like tomatoes, cauliflower and garden flowers.

Potassium (K) boosts plant hardiness, stem strength, resistance to disease and drought which is important to all crops, but especially in potatoes, celery and rhubarb.

👍 Rule of Green Thumb: For foliage plants, provide them with shade and lots of nitrogen, and for flowering and fruiting plants, provide them with lots of sun and lots of phosphorus!

Amending Clay

Hello Haldimand and Eastern Norfolk!

   We’re presented with the challenge of compacted, often shallow and waterlogged clay, which proves difficult but not impossible.

   Clay becomes compacted and waterlogged as it is the smallest soil particle – smaller than a grain of sand, and even smaller than silt – with rough edges that allow it to interlock and bind. In this instance, roots cannot penetrate further into the soil, are susceptible to root rot, and air pockets are slim to none.

   This, however, can be fixed with the addition and renewal of the above materials.

  Mindful that you don’t create a watery bowl in the ground (score the edges the area being worked), you can add organic matter (i.e., manure, compost, and potting soil) for nutrients, as well as mulch, sand and perlite for aeration and drainage. Annual soil particle aggregation in clay soils increases air porosity (air pockets) and is accomplished by the incorporation of organic matter that breaks down to form humus.

   If started too soon, your plants will be leggy and overgrown long before you can transplant them into the garden. The general rule of thumb (even if yours isn't green), is if the seed packet recommends sowing four to six weeks before the last frost date, it's better to pick the four - rather than the six-week date (to calculate the sowing date, count back from the third week of May).

   In this blog post, we’ll discuss the proper timing of the beneficial companion planting practice, to ensure an organic triple-play of pesticide reduction, nutrient sharing, and the fruits of your labour actually tasting better!

What is Companion Planting?

   The use of companion plants is an organic approach embracing plant diversity that involves growing certain different types of plants near each other. By mixing a variety of plants together you confuse harmful insects (i.e., the ‘Three Sisters,’ corn, beans, and squash). When you plant certain vegetables together or alongside flowers or herbs, you can often camouflage the scent of a given plant so that its potential enemies can't find it. For example, if you plant onions and carrots together, the Carrot Rust Fly can no longer detect the scent of its "prey," the carrot.

☝️ Plants also share nutrients and amend the soil below ground – in the instance of the Three Sisters, beans fix the nitrogen content of the soil for corn, who has long lost its ability to produce its own nitrogen.

What to Plant?

Herbs Make Excellent Companion Plants

Instead of grouping them all together in a corner, plant them in among your vegetables. Tarragon and marjoram give off a scent that repels most insects. Sage, rosemary, and thyme repel insects that feed on the different plants of the cabbage family. Plant these herbs near your cabbage, cauliflower, and brussels sprouts. Coriander attracts parasitic wasps that are very useful in controlling all sorts of pests.

Why Not Try Flowers in the Vegetable Patch?

Nothing will make your vegetables happier! Plant borders of alyssum and cosmos; these attract beneficial insects and repel certain harmful ones. Marigolds protect tomatoes from threadworms, and nasturtiums and petunias attract aphids. If you plant them near your tomatoes, the aphids will choose the flowers instead of your tomatoes.

Meet My Plant Friends!

Plant friends are plants that can be grouped together because they mutually help each other grow. Basil stimulates the growth of Tomatoes and enhances the quality of the yield. Chamomile improves the growth and taste of cabbage and onions. It has been found that peas and beans enhance the growth of cucumbers and potatoes. Peas and beans also repel the Colorado Potato Beetle that commonly attacks potatoes and eggplant.

   Once you’ve decided who is going where, it’s time to focus on when who is going where.

When To Plant?

It is important to know when the last spring frost date is for your area. Many plants need to be planted after the last frost, so that they don't freeze their little buds off! Follow this guide so that you can have healthy, sturdy little plants that will become good friends in your garden this summer.

Ten Weeks Before Last Frost Sow indoors: broccoli, brussels sprouts, cabbage, cauliflower, eggplant, lettuce, peppers, and onion

Eight Weeks Before Last Frost Sow indoors: tomatoes Sow outdoors: spinach

Five Weeks Before Last Frost Sow indoors: marigolds (do not transplant until after last frost) Sow outdoors: peas Transplant: broccoli, cabbage, cauliflower, onion

Four Weeks Before Last Frost Sow indoors: cantaloupe, cucumbers, okra, pumpkins, squash, and watermelon

Three Weeks Before Last Frost Sow outdoors: carrots Transplant: brussels sprouts, hardened off frost-hardy herbs like chives and oregano

Week of Last Frost Sow outdoors: pole beans Transplant: cantaloupe, eggplant, lettuce, okra, peppers, pumpkins, squash, tomatoes, and watermelon

BONUS: Tips on Ensuring Your Seeds Have the Best Start!

🌱 To ensure success it is always best to use fresh, sterile seed-starting mixture (available from garden centres). Moisten mixture about an hour before sowing; it shouldn't be soggy, just as damp as a wrung-out sponge.

🌱 Follow the information contained on seed packets in terms of timing, lighting requirements, sowing depth, and optimal germination and growing temperatures.

🌱 Lightly water freshly sown flats, then cover with plastic dome lid, or if reusing containers try placing them inside a plastic zip-lock bag. At the first signs of germination, uncover or remove from plastic bag.

🌱 As the seedlings develop, wait until the top of the soil looks dry, water carefully using a small watering can with a fine spray. Avoid over watering: soggy soil and poor air circulation can lead to damping off, a fungal disease that can kill seedlings.

🌱 Locate your seeding flat in a bright window but grow lights or cool fluorescent tubes are better. Keep seedlings about eight to 10 centimetres from light source to prevent plants from becoming too spindly. Plug lights into an automatic timer set for 16 hours on, eight hours off. Be careful if you’re using the windowsill method though, as extremes in temperature may occur from hot drying sunny days to frigid evenings.

🌱 When seedlings have two sets of true leaves (the first leaves are called cotyledons — or seed leaves — so wait for the true ones, start feeding once a week with a balanced (20-20-20), water-soluble fertilizer at half-strength, working up to full strength after a few weeks.

🌱 Finally, the plants which have been raised under sheltered conditions must now be hardened off (see more here) before planting out. Gradually lower the temperature and reduce the watering while exposing the plants to brighter light for seven days prior moving them out to a cold frame. Keep an eye on the weather as sudden changes, as it often happens in spring, could spell disaster to your young plants.

Many home gardeners are really missing their harvest of fresh vegetables these wintry days – and many beginners have New Year’s resolutions to become greener thumbs.

Seeds to Start

The seeds of many vegetables and beans are suitable for hydroponic sprouting into tasty young shoots that will be ready for the table in less than a week!

   Seeds such as alfalfa, broccoli, clover, lentil, mung bean, mustard, onion, radish and soybean are excellent choices for this activity plus they are invaluable in terms of their nutritional content.

Sprouting seeds on your kitchen counter takes only minutes a day, and the reward is a steady supply of fresh, crunchy shoots.

   It is important to start by purchasing some packaged seed expressly for sprouting. The directions will indicate how much is needed to produce 100 grams of sprouts. The seed-to-sprout ratio can differ substantially - anywhere from 1.5 to 8.5 units of sprouts or more per one unit of seed - so follow directions carefully and make sure your jar is large enough to accommodate all the sprouts while still leaving room for good air circulation. As a rule, begin with 1 tbsp. (15 mL) of seeds for small varieties such as alfalfa and radish, 2 to 3 tbsp. (30 to 45 mL) for medium ones such as lentil, and up to 4 tbsp. (60 mL) for large seeds such as beans and peas.

Seeds to Sprouts

Simply put seeds into jar and position screening over opening, using an elastic band to hold the covering in place. Fill jar one-third full of warm (about 40°C) water and swirl seeds around for a minute or so. With the covering in place, drain water. Refill jar one-third full of cool water and let seeds soak for four to eight hours.

   Next, begin daily regimen of rinsing seeds three times a day at roughly eight-hour intervals. Drain and refill jar with cool water, swirl seeds for about 30 seconds and drain again. Then, invert the jar so screening is at the bottom and rest it at a 45-degree angle in the bowl. Place on the kitchen counter out of direct light (place bean shoots in complete darkness, as they often taste sweeter when they're grown this way). Repeat this process for three to five days.

Simple Sustenance

You can start to harvest your sprouts once they're three to five centimetres long. Rinse and drain them thoroughly and place them in an airtight container and refrigerate immediately; they should remain fresh for up to five days.

   Clover, alfalfa, radish, and mustard seeds give rise to the delicious sandwich booster sprouts. Sprouts are one of the most concentrated natural sources of vitamins, minerals, enzymes, and amino acids.
