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.

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.

How to Stay Warm and Stylish

By Ava Green

Colder temperatures are around the corner, and some of us are not looking forward to it! Whether you love winter or not, Sassyfras Boutique inside Eising Greenhouse and Garden Centre has the cozy, stylish clothes you need to look your best and stay warm all season long. 

Begin with Layers

Fall, winter, and spring can all bring unpredictable weather to our corner of southern Ontario, so layering is key. Winter is an especially good time to follow the 3-layer rule:

• A base layer keeps you dry
• A mid-layer adds warmth
• An outer layer protects from the elements

Build Your Cold-Weather Capsule Wardrobe

Creating a winter capsule wardrobe makes dressing warm and stylish easy and stress-free. Here are a few ideas to get started:

Base Layer: 

Start with a basic tee, a long-sleeve mock neck, or a long-sleeve crew neck top. Choose natural fabrics that wick moisture and keep you dry. 

Tights or leggings make a great foundation under dresses or pants for added warmth. 

Mid Layer:

For warmth, add a sweatshirt, a crewneck sweater, a v-neck sweater, or a turtleneck. 

If you’re stopping at two layers, choose a chunky knit or oversized sweater for a cozy statement look.

On top of your tights or leggings, try a faux-suede skirt, faux-leather pants, wide-leg trousers, jeans, or a dress, maybe even a comfy sweater dress. 

Outer Layer:

Top it all off with an eye-catching outer layer! Try a bomber jacket, blazer, faux-fur jacket, puffer vest or jacket, or a trendy coatigan for warmth and style.

Accessorize to Elevate Your Look

What makes an outfit really stand out? The accessories! At Sassyfras, you’ll find everything you need to complete your winter look.

From belts (perfect for cinching a blazer or dress) to trendy handbags, classic tote bags, sunglasses, and a wide selection of everyday jewellery, including locally made, one-of-a-kind pieces. You’ll find the perfect finishing touches that reflect your personal style.

Mix, Match and Stay Cozy

Once you’ve built your base, mid, and outer layers, the fun begins! Mix and match your pieces to create new combinations that make winter dressing simple, cozy, and chic. 

With just a few well-chosen items from Sassyfras, you’ll be ready to step out in style, no matter how cold it gets! ❄️

Spring is the time of year known for new beginnings, and it’s also a very busy season in the garden as we hurry to get everything planted for the summer growing season here in Southern Ontario. But, did you know that fall is also an ideal time to get planting? 

Similar to spring conditions, the cooler temperatures and more frequent rainfall make it easier for new plants to transition. This also decreases transplant stress. There’s time for roots to become established, and by springtime, you’ll be enjoying your plants instead of being busy planting them!

Don’t wait too long, though! At Eising Greenhouses, we recommend planting perennials, trees and shrubs before Thanksgiving weekend to give your new plants a little time to settle in before a hard frost arrives. A hard frost, or freeze, is when the temperature dips below zero for an extended period of time, killing tender plants.

What to Plant in Fall

Spring-Flowering Bulbs

Tulips, Daffodils, Hyacinths, Crocus, Fritillaria and Alliums are just some of the bulbs that need to be planted in the fall in order to enjoy their flowers in the spring. Tulips especially appreciate being planted in cooler weather, but all of these bulbs require a cold period of about 12 weeks in order to grow in the spring. Many bulbs can be planted right up until the ground freezes. But why wait?!

👉 TIPS: While Tulips can be tasty and tempting for squirrels, rabbits and deer, many bulbs like Alliums, Frittilaria and Daffodils are not so delectable. Tamping down the soil after planting your bulbs makes it more difficult for critters to sniff them out. Laying some chicken wire over the area can also help deter from your bulbs becoming a meal for a critter.

Be sure to choose an area to plant your bulbs in that does not stay wet so the bulbs don’t rot.

Garlic

While some folks choose to plant garlic in the early spring, many people choose to plant it in the fall. Why not get started now? When you plant your garlic in autumn, you will have a crop that’s ready for harvest next summer.

Plant, Divide, and Transplant Perennials

Yes, you can still plant perennial flowers in the fall! Whether you’re purchasing new plants or moving plants around, autumn is a great time of year to do it.

It’s also a great time to divide and transplant spring and summer blooming perennials. Why divide your plants? It’s a great way to revitalize the plant and also to create new plants.

Whether you’re planting, dividing or transplanting perennials, it’s best to do it 4-6 weeks before the first hard frost so that they have time to become established in the soil. Perennial plants will be available for sale at Eising Greenhouses until Thanksgiving weekend, so don’t delay too much!

Trees and Shrubs

Container-grown or burlap-wrapped trees and shrubs can be planted as long as you can get a shovel in the ground! However, it’s a good idea to give them a few weeks in your garden before it freezes if you can.

It’s especially nice to see what a tree or shrub will look like in the fall before you plant it.

Peonies

Autumn is the best time to plant and establish roots so your peony is ready to bloom in spring! Planting them 4-6 weeks before the first hard frost will help your plant become established before cold weather descends.

👉 TIP: Be sure to add mulch to trees, shrubs and perennials after planting. But keep the mulch away from the trunks or stems. It’s never a good idea to put decaying plant material right up against a living plant!

Come in and take a look at what’s available, then enjoy the cool fall weather for planting!

While many gardeners in Southern Ontario follow the popular planting date of May 24th, when we’re usually safe from frost, you may be surprised to know that April is not too early for certain plants!

Once the ground has thawed and is workable, there’s plenty you can start growing. In Zones 6a-6b, this usually happens around four weeks before May 24th. While frost is still a possibility, many cold-tolerant plants not only survive a light frost but thrive in cooler weather. To check if the soil is ready, simply dig up a handful and squeeze it. If it sticks together, it’s too wet to work with—wait a few more days for it to dry out. Once the soil is ready, it’s time to plant those cool-weather crops!

Cool Weather Vegetables

Radishes: Radishes are fast-growing and perfect for planting in April because they love cooler weather. Sow them directly from seed.

Peas: April is the perfect time to plant peas outdoors as soon as the soil is workable. Soak pea seeds in water for 8-10 hours before planting them to help germination.

Lettuce, Spinach, Arugula, Asian Greens (Tatsoi, Mizuna, Pak Choi and Leaf Mustard) : It’s best to sow seeds for leafy greens or plant seedlings early in the spring as they will grow quickly in cool weather. Plant more seeds or seedlings every 10-14 days for a succession of greens until hotter temperatures make them bolt (go to seed) and become bitter.

Potatoes: Seed potatoes can be planted in mid to late April as soon as the soil is workable.

Onions: Plant onion sets or seedlings that have already been started in early spring and enjoy a harvest in late summer or fall.

Carrots: Plant carrot seeds in April, and they will be ready for harvest later in the spring or early summer. They take a little longer to grow, but planting early gives you a head start. You will enjoy carrots all summer long by planting more seeds a few weeks later.

Tip: It’s a good idea to keep some frost protection like row cover handy for lettuce, peas and spinach just in case the temperatures dip below zero.

Bonus: Many garden pests, like earwigs and slugs, are still overwintering in April and won’t feast on your tender plants.

Cold-Tolerant Flowers

Pansies: Add a pot of Pansies to cheer up a front porch, and it instantly feels like spring! Plants can go into a sunny spot in the ground when temperatures reach 7-21 celsius and are regularly staying above freezing.

Violas: These cool-weather flowers can withstand light frosts and are perfect for containers or for planting in garden beds

Gladiolas: Even though the weather is still cool, this resilient summer-blooming bulb can be planted in a sunny area of the garden in April. 

Bonus: Pansies and Violas also love cool weather in the fall.

Perennials, Trees and Shrubs

Two to three weeks before the threat of frost has passed, many potted perennials, shrubs and trees, either dormant or with leaves, can be planted. (If you’re not purchasing from us, be sure to check whether the plants were grown outdoors or acclimated to cooler temperatures and ensure they’re hardy enough for Southern Ontario.)

While perennials, trees, and shrubs can be planted throughout spring, summer, or fall, the combination of warming soil and increased rainfall in spring creates the perfect conditions for successful transplanting.
