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.

🖱️ See more on companion planting with herbs here.

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.

Bearing in mind that a lawn is a very unnatural situation in that we are trying to sustain a large area with very little plant diversity (monoculture), in the eye of the homeowner, lawns may remain an important part of the domestic landscape! As well as in very necessary areas like tile beds, paths, roadsides, and recreational areas, lawns provide a background that enhances the overall effect of the home and the various gardens and landscape features.

   From nematodes to dog pee spots, the following tips will help you to maintain a healthy lawn naturally.

Mowing

Of all the cultural practices, mowing exerts the greatest influence on growth, development, and ease of management. By keeping the grass blade height between 6 & 8 cm (2.5 to 3 inches) high you'll be able to produce a more competitive lawn against young and germinating weeds.

Grass Species Selection

Seed mixtures with Titanium Tall Fescue have shown to be more drought, disease, and insect resistant than many other lawn grasses such as the traditional Kentucky bluegrasses. Tall fescue roots penetrate deeper into the soil providing better regrowth and wear tolerance, making it ideal for heavy foot traffic areas and recreational areas.

Time of Sowing

The best time to establish a lawn from seed is late summer and early fall (mid-August to mid-September) in southern Ontario. During this period, soil moisture and temperature conditions are optimal for germination and establishment. There is also less competition from germinating weeds in the fall. Make sure that seeding is done early in the fall so that the grass is well established before winter. The plants are then well rooted and more drought- and heat-tolerant the following summer.

Seed the shady areas in the fall for best results. Trees will have shed their leaves by then, so plenty of light is available for the new growth. The grass also gets off to an early start in the spring before the trees leaf out.

Spring seeding should be done as soon as the ground can be worked. Slow, irregular germination may result if the seed is sown when the soil is too cold and damp. (Soil Temp. around 15oC is ideal and there is also strong competition from germinating weeds during the spring. When practical, wait until weed seeds germinate, work the land to kill them and then sow the grass seed. ) If you choose to plant your new lawn in the spring, begin just as soon as the soil is dry enough to work, preferably mid-April to mid-May. This will give your new grass time to get well established before the hot, dry weather sets in.

Fall is often a better time to start your lawn, from mid-August to the end of September. Your seedbed is less likely to dry out at this time of year, and the grass should be well established before winter.

Watering

Your typical lawn needs about 2.5 cm (one inch) of water per week through either rain or irrigation. If irrigating, water in the morning as more will be absorbed as opposed to being lost to evaporation in the sun and the warmer temperatures later in the day.

Fertilization

Lawns require relatively large amounts of nitrogen-based fertilizers which should be applied several times during the growing season. Since lawn clippings are high in nutrients, especially nitrogen, much of your initial nitrogen fertilizer investment may be recycled back into your lawn! A fertilizer with a nitrogen, phosphorus, and potassium ratio of 4:1:2 (e.g., 20-5-10) is normally the best in most situations. It should be noted though, that a soil nutrient test can accurately determine the actual needs of your lawn including lime if the pH is too low.

(Lawn Liming Rate: 20-50 lbs/1000 ft2)

Corn Gluten

An application of this product early in the spring and then later on in the summer will inhibit the growth of weeds from germinating seeds especially the annual problem, crabgrass. Established weeds though have to be dug out by hand.

Dog Pee Spots

There is a misconception that the pH level of your dog’s pee is leaving those unsightly spots in your lawn, when it is in fact the high concentration of nitrogen and salts being introduced into the soil. To prevent this, should you see your four-legged friend raising its leg or popping a squat, give that spot a good watering to dilute the minerals. In addition to this, ensuring your dog is well hydrated will help to water down their urine. However, your lawn may already have several severe yellow and bald patches. You may opt to resod or reseed the area, but the soil is what’s affected. Before giving up altogether and adding a scree to the affected area, Eising Greenhouse and Garden Centre offers a fertilizer to help balance and remedy your dog pee spots!

Thatch Control

Thatch is a layer of dead leaves, stems and roots that intermingle with the living plants above the soil surface. A one-inch layer of thatch is desirable as it has a cushioning effect against compaction and an insulating effect in cold weather. De-thatching a lawn is an extreme measure that may be considered if the drainage is poor. Lawn aeration may be required as well as the lawn and the soil below must establish a drainage pattern.

Nematodes - Aid Against Japanese Beetles and More!

If the Japanese Beetle has been destroying certain plants in your landscape plantings or their grubs have been feeding on the roots of your lawn, causing unsightly brown patches maybe it's time to use Mother Nature's secret weapon: Beneficial Nematodes.

   Beneficial Nematodes are a natural way to control Japanese Beetle grubs and over some 200 species other pest insects in your lawn while having no detrimental effect on Ladybugs, Earthworms, and other helpful beneficial insects.

   Nematodes are naturally occurring microscopic worms of the soil and are used to control soil pest insects in their larvae or grub stages while not posing any health or environmental risks to humans or animals. The beneficial Nematodes enter the JB larva via mouth, anus, or respiratory openings and begins to feed. This causes specific bacteria to emerge from the intestinal tract of the Nematode, spreading inside the insect and multiply very rapidly; the bacteria convert host tissue into products which can easily be taken up by the Nematodes, ceasing the soil dwelling pest insect within a few days. Beneficial Nematodes are effective against not only the larval or grub stage of Japanese Beetles, but the Northern Masked Chafer, European Chafer, Rose Chafer, Crane Fly larvae (Leather Jackets), Oriental Beetles, and June Beetles.

   The nematode product you purchase should contain two genera: Steinernema and Heterorhabditis for better grub control.

   Beneficial Nematodes are very easy to use. Mix with water and spray on the lawn with a water-can, irrigation system, or a hose-end sprayer. Most homeowners spray at a rate of 10 million nematodes per 600 square feet on grub damaged lawns. After an application, keep the soil moist during the first two weeks for the nematodes to get established.

   In Ontario, there are two windows of opportunity to apply Beneficial Nematodes to be effective against the JB grub stage.

   The first application should be in May as the soil warms up and then again at the end of August or the first two weeks of September as the JB are hatching into their first larval stage.

Now is the time to prep our outdoor landscapes for the coming cold weather and the ensuing spring! Perhaps your autumn is calmer than your spring, and this is the best time to clean up and begin new projects. The following are some simple but effective tips to get your yard winter-ready - so your spring will be a little more pleasant for you!

Planting

When warm weather still allows it, plant trees, shrubs, perennials, and bulbs to allow them to establish for budding and blooming next spring.

Pond Care

Mary, our perennials gal, suggests not removing any water from your pond but instead aerating it all winter. She skims out the leaves to maintain the balance of the nitrogen cycle in the water and suggests waiting to do a big pond clean out in the spring, as that’s when the water’s culture can bounce back easier.

Fertilizing

After top growth of your landscape plants ceases, reduce your annual fertilizer application by up to half of the requirement. Autumn is a major root growth period for woody and herbaceous perennials; roots will grow and absorb nutrients whenever soil temperatures remain above 5 °C but can be over fertilized quickly in these cooling temperatures.

Produce gardens could benefit at this time from a top layer of compost that will break down during the winter so it isn't too 'hot' for spring planting.

Leaf Litter

Here’s our pitch on the ‘leave it – don’t leave it’ debate: It DEPENDS.

   Ideally, we should leave litter leaf on the ground for our pollinator friends and endangered species like fireflies to hide out in the winter. But, there are appropriate situations in which to remove leaf litter.

• When they’re covering your bulbs and tender perennials, remove SOME. Leaf litter acts as a ground insulant, which can amplify our temperamental zone 6b temperatures. This freezing and thawing can often confuse and kill early spring bulbs and tender perennials.

• Zach, our trees and shrubs guy, suggests that if a tree shedding leaves has been diagnosed with pests and fungi, remove the leaf matter to reduce the spread to other plants. Diseased matter should always be removed in a quarantined fashion and taken to a landfill or burned.

☝️Please note: Unless diseased, compost your leaves, they contain vital nutrients specific to the plants they came from!

Lawncare

With autumn mowing practices you have the opportunity for the addition of much needed organic matter for your lawn, which is also an excellent source of slow release nutrients. Keep mower blades sharp since leaves can be tougher than grass. Raise the mower height up and mow leaves when they are lightly wet (e.g., morning dew). This will keep the leaves from blowing all over and will prevent the mower from getting bogged down in wet leaves.

See more on general lawncare in Dave's Lawncare 101 post.

Clean Up

Now is a good time to wash your tools with soap and water to prevent diseases spreading from plant to plant.

  ☝️Mary's tip is to spray garden tools with PAM before use, so the dirt slides right off them!

Pruning Perennials

Mary, our perennials gal, suggests leaving things until frost to cut back. This way they're easier to compost. Make sure to leave seedheads (i.e., coneflowers and black-eyed Susans) for wildlife, and things like hydrangeas for winter interest.

☝️Make sure if things are cut back, to leave them sticking up enough you can still find them in the spring!

Dividing and Moving Perennials

Moving or dividing perennials in the autumn is a great way to reduce your work next spring. The cool, moist weather is an ideal time for perennial roots to become well established.

👍The rule of green thumb for moving perennials: If the plant blooms between early spring and late June, then early fall division/moving is ideal. If the plant blooms after late June, then early spring division is ideal (except for Peonies which should only moved or divided in the fall, Poppies in August, Irises in July & Lilies in the Fall).

Overwintering Trees

Zach and Sandy from trees and shrubs suggest a couple of things to help your favourite trees along this winter:

• To reduce winter injury in evergreens: Keep properly watered throughout the growing season and into the fall is another way to reduce winter injury. Decrease watering slightly in September to encourage hardening off, then water thoroughly in October until freeze-up.

• Cedars - Spray cedars with antidesiccant spray (available at Eising GC) or wrap in burlap (with stakes to create dead air space) so wind doesn't dry out and burn tips.

• Fruit trees - In late fall, spray fruit trees with sulfur-horticultural oil (available at Eising GC) for protection against fungi and pests overwintering in the bark.

• Ornamental trees - wrap the base of young trees to protect from chewing rodents. 

• Pruning trees - trees that prefer winter pruning rather than spring pruning are maples, oaks, birches, and elms, as well as with fruiting trees such as apples and pears. This ensures blight and pests will not affect the tree's open wounds.

If you missed the frosty deadline for transplanting trees, Sandy suggests insulating unplanted potted trees to help them best survive the coming winter. Here are some methods:

• Double-pot your tree with an insulative barrier (i.e., burlap, straw, mulch, etc.) stuffed between the two pots and securely cover the top with tarp to deflect moisture.

• Bury your potted tree in the ground, level with the top of the pot (don’t forget to dig it back up!) and mulch the area.

• Huddle all of your unplanted trees and plants together when using the above methods.

Mulching

Mulching is one of the simplest and most beneficial practices you can do for your garden. Just by simply placing a protective layer of material over the bare soil will benefit the soil as it decomposes providing the much-needed organic matter which improves root growth, the infiltration of water and the nutrient-holding capacity of the soil while reducing soil erosion.

   A good layer of mulch allows the soil to warm more slowly in the spring, so perennials aren't fooled into breaking dormancy too early, as you want the ground to stay cold until it really is spring!

☝️Make sure your mulch application won't stunt the growth of your plants come spring as discussed in our Transplant Troubleshooting blog post!

Japanese Beetle Prevention

Nematodes are microscopic worms that should be applied to lawns that have been ravaged by grubs especially of the Japanese Beetle. Nematodes have a short shelf life and must be refrigerated until they are applied. Normally, they are sprayed onto the lawn from mid-May to mid-June and then again (for best practice) from mid-August to mid-September.

Pots

To prevent freezing and cracking, Mary suggests emptying and turning your pots upside down. You can disinfect at this time too. 

Design Time!

Jeanine, from production, suggests writing down what worked best in your produce garden this year so you can implement it again in the spring.

With the trees and land being barren enough you can see its contour, now is a great time to plan ahead for spring landscaping! Don't forget Eising GC would love to offer help with your landscape designing!
