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 Keep Your Hanging Basket as Gorgeous as the Day You Brought it Home, All Summer Long!

By Dave Zeldon and Ely Schweyer

Remember your Mother's Day hanging basket with its variety of colours, textures, and plant combinations? Maybe there was Verbena cascading elegantly with their colourful star like blossoms, double Begonias for the porch in spectacular shades of reds, pinks, and burgundies, and of course the vigorously growing Petunias and Geraniums, to name just a few. But as the Summer goes on, they just don’t seem to have that same stamina.

   To keep your hanging baskets in great shape and avoid the dry, wilted, bald spotted, leggy look that occurs to containers every August, one should follow these easy tips.

Watering

Plastic, fibre, and especially moss lined baskets dry out quickly. They should be checked twice daily and watered every day. Be sure to wet the moss sides as well.

   Try to maintain uniform soil moisture. When watering, fill the top of the container with pooling water until it ‘pees,’ and allow it to drip out of the bottom of the basket every time you apply water. Frequent severe wilting will impact upon the quality of the basket.

   At this time of year, one could take the basket down and soak it in a tub of water for 20 minutes to hydrate the entire root ball, once every week.

Deadheading

Remove spent flowers on a weekly basis (this is called deadheading) to prevent plants from going to seed. This will encourage more flower production. Part of the beauty of the mixed basket is its prolonged display, just like in your garden.

Check for Pests!

During your weekly deadheading, keep a watchful eye out for aphids, whiteflies, and caterpillars. If you see any, try a quick spray of insecticidal soap to keep them from becoming an infestation.

🖱️ If you're noticing fungus gnats in your hanging baskets, find more on eradicating them here!

Pruning

Not every plant in the basket will be at its peak all season.

   Cutting plants back after a flush of bloom will tidy them up and prepare them for a fresh crop of flowers. Meanwhile, other varieties will begin putting on a show. This is especially true for Petunias.

    A good cut back of long, lanky branches will reap benefits.

Fertilizing

Daily watering means nutrients can leach out of the soil before the plants can absorb them. The baskets should have both slow release granular added to the growing media and a weekly feeding of 15-30-15 soluble fertilizer. Use a solution containing micronutrients, as plants like Petunias need extra iron.

Sheltering

It has been suggested, if possible, that during stretches of extreme heat, give your baskets a break and move them to a cooler, shaded spot to de-stress for a couple of days. This is also suggested when heading on vacation. Your flowers will rebound to their former beautiful selves!

We hope this long term hanging basket care guide helps you enjoy your purchase all summer long! For more information - and beautiful plants – visit Eising Greenhouse and Garden Centre! 🌸

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.

How To Keep Your Orchid Alive

By Ava Green

Orchids have become very popular gifts, and a great hobby for indoor plant enthusiasts who discover the wide range of colours and shapes available. Orchids are also loved for their long-lasting and exotic blooms.

While some may choose to only enjoy these tropical plants as long as they’re blooming, orchid-lovers look forward to nurturing the plant and encouraging it to flower regularly. It may be a little daunting at first, but once orchids grace you with their stunningly beautiful blossoms, you will find that a little bit of care is very worthwhile!

It’s estimated that there are 25,000 different species of orchids and over 100,000 hybrids! The ones you’ll find most readily in Ontario stores are Phalaenopsis or moth orchid, because it’s fairly easy to grow. Phalaenopsis are the best choice for beginners.

Other orchids you may find easily are Cattleyas (Corsage Orchids), Cymbidiums (Boat Orchids) and Dendrobium orchids.

While all of these may be orchids, they don’t necessarily require the same care, so it’s a good idea to check the tag for the type you have and its specific care requirements. The following is a general guide to light, water, fertilizer, and growing medium for the most commonly found orchids, but it does not apply to all breeds.

Light and Air

For most orchids, light, and lots of it, is the general rule. Place your plants within 3 feet of a window (not to the side) in the sun. South, east, and west-facing windows are all fine for maximizing the light your plant receives.

Orchids also enjoy a breeze or circulating air in your house. They do not like temperature extremes, though 15 to 20 degrees Celsius is safe. Keep in mind that the more warmth and air movement there is, the more often you will need to water your orchid.

Water

A general rule is to use water that is not hard and has not been softened with salt. Salt will kill an orchid. Rainwater, reverse osmosis, or distilled water are good choices. Chlorinated water is not an issue for orchids - high sodium levels are.

The biggest issue many people have is either over-watering or underwatering their orchids. Here is the method we recommend:

Every 5-7 days, place the pot in a container or the sink, then fill it with enough water to cover the top of the pot. Be careful not to let water collect in the crook at the base of the leaves, as standing water will rot the leaves and the plant. Once the plant’s growing medium is thoroughly soaked, remove it from the water and allow the pot to fully drain in the sink before placing it back in its saucer. 

We prefer using a container of water rather than the sink, so the remaining water can be used to water other plants.

Here’s the best watering advice we can give you: look at the overall health of both the plant AND its root system. Full, plump leaves and vibrant, green roots indicate that your plant is getting enough moisture. Puckered leaves and a silver sheen on the roots indicate insufficient water. Mushy, brown leaves and roots are signs of rot caused by too much water.

You may hear of another watering method that involves using ice cubes, but it’s controversial and not widely recommended. To quote the American Orchid Society, “Ice is for cocktails, not orchids. Never use ice on tropical plants to water them.”

“Soil” and Nutrients

Most orchids naturally grow high up in trees, where their roots cling to bark and absorb moisture from the air. At home, we try to mimic those conditions, which is why orchids are typically planted in chunky mediums like bark, coconut husk, charcoal, or perlite rather than traditional soil. While many of the roots stay inside the pot, it’s completely normal for some to grow up and over the edge.

These “escapee” roots might look a little wild, but don’t worry, there’s nothing wrong with your orchid. In fact, those aerial roots are a sign that the plant is healthy and doing exactly what orchids do in nature.

It’s worth noting that not all orchids grow the same way. Many, like Dendrobiums, are epiphytic (growing on trees) or lithophytic (growing on rocks), though some orchid varieties are terrestrial and grow in the ground. The good news is that the growing medium your orchid comes in is chosen specifically for that variety, so you can trust it’s in the right environment.

The bark that your orchid is planted in will slowly break down and become mushy. It’s a very good idea to repot your plant every two years.

It’s generally recommended to feed most orchids, and bloom time dictates which fertilizer to use and how often to feed. Begin by using a water-soluble 20-20-20 fertilizer, mixing it at ¼ the amount recommended for other houseplants. Apply this solution every 2 weeks in the summer and every 3 weeks in the winter.

“The orchid, with its many forms, is a reminder that life is full of surprises.” — Leonardo da Vinci.

Lastly, here’s an orchid fun fact: While we have been talking about tropical orchids in this article, there are also orchids that grow right here in Ontario! That’s right, there are over 50 species in this province, including the much-loved Pink Lady’s Slipper (Cypripedium acaule).

This is the time of year that most garden centres will have on display their wide variety of Amaryllis bulbs, including the evermore popular waxed dipped. These enormous bulbs that are appearing now will be ready to burst into bloom within 4-8 weeks after planting.

Non-Wax Dipped: Planting

All Amaryllis need is a bit of commercial potting soil that should not cover the shoulders of the bulb (try leaving about 1/3^rd of the bulb showing above the soil line), with the nose (or narrow end) of the bulb peeping well over the top of the pot. Make sure that you use a well-drained container that is 3-4” bigger in diameter than the bulb itself.

☝️A heavy clay pot will prevent this top-heavy plant from toppling over. To achieve continuous bloom, plant at intervals of two weeks for stunning colour in your home.

Non-Wax Dipped: Care

Once leaves emerge, fertilize once a month with a 20-20-20 water soluble fertilizer for houseplants. Water sparingly and wait for the miracle in a warm sunny room. Sub-irrigation or watering from the bottom of the drip tray will keep the surface soil dry, thus keeping and bulb rot organisms and those pesky fungus gnats at bay.

Non-Wax Dipped: It's Not Done Yet!

When blooming is over, remove the scape (or flower stock) and place the plant in a sunny spot and continue to water. This is to allow the leaves to regenerate the bulb. In springtime, when all danger of frost has passed, bring the bulb outdoors and let it spend its holidays in a shady spot. In some varieties the leaves will die back in September to give the plant a rest for a couple months. Stop watering and store the bulb on its side in a cool place for about eight weeks, when the leaves will once again begin to emerge.

   Amaryllis can go 3-4 years without repotting as they don’t mind a little crowding. Try growing a couple of bulbs in larger pots to see if you can get a clump of flowers from the offshoots or babies that will develop after a couple of years.

Or, Try One of These Wax Dipped Bulbs!

Now growing more popular are the care-free waxed-bulb Amaryllis!

   Experienced growers and beginners alike love that these waxed bulbs do not need to be planted or watered! Each of these robust bulbs are carefully prepared in festive-coloured wax, allowing you the freedom to place them among your holiday decorations.

   Simply keep the bulbs at an ambient room temperature of at least 16C (70F)  for beautiful blooms in five to six weeks. 

   These novelty items are low commitment! Their only fault is their lack of longevity - gardeners don’t get to enjoy them after year as these waxed bulbs were designed to be a one-use throwaway item!

   BUT with a little luck and perseverance you may be able to save the bulb for next season after blooming. All you have to do is to carefully remove the wax layer, remove the flower stalk and place the bulb and with its remaining leaves into a pot of good growing media, allowing the leaves to regenerate the food stores in the expired bulb.

If you’ve ever wondered how the warm weather succulent came to be a seasonally regarded indoor plant, or how to keep one going, read on!

History and Cultural Significance

The Poinsettia was named after Joel Roberts Poinsett, the first U.S. Minister to Mexico. He introduced this native Mexican the United States in 1828. In the Mexican Christmas tradition, the star-shaped leaf pattern is said to symbolize the Star of Bethlehem, and the red colour represents the blood sacrifice through the crucifixion of Jesus.

   Since the species is native to Mexico and found in the wild in deciduous tropical forest at moderate elevations, we then have a challenge to keep this plant alive and in a healthy form in our colder, northern climate.

It's Just A Rumour!

There is a common misconception that the poinsettia is highly toxic. This is not true.

   Yes, it may be mildly irritating to the skin or the stomach if it is eaten, but otherwise, there have been no documented cases of poisoning. The origin of this myth could be found in the fact that most plants of the spurge genus (Euphorbia) are indeed toxic. Fortunately, this family member is a good one!

Here are Some Helpful Hints to Get the Most Longevity Out of Your Plant:

☝️Unsleeve the plant as soon as possible as the leaves may become droopy if left too long in the wrapper. Fortunately, the plant should recover in a few days if this does occur.

☝️If you want to try to keep your plant until next Christmas then fertilize after the blooming season with an all-purpose fertilizer, repot it later in the early Summer and then introduce it to 12 hours of uninterrupted darkness come September.

Figures.

By Dave Zeldon and Ely Schweyer

Now that we’ve brought our plants inside the house to over-winter, we begin to notice those slender, dark gray flies (0.2- 0.4 cm long) flitting about atop the pot soil. Yuck!

   These insects are known as fungus gnats (Bradysia sp.). Whereas they are considered only to be a minor nuisance in house plants, due to their sheer numbers hovering around an attractive plant, they can certainly take away from its appeal. Below is a bit about these pests and some basic control measures.

How Do Fungus Gnats Affect Your Plant?

Other than their swarming presence, fungus gnats are not a direct threat to your plant, but an indirect threat. As their name implies, they are concerned with snacking on the fungi mycelium living in your plants’ soil. (Yes, it’s there and it’s a good thing!) However, these little flies can transfer disease between plants, making them nuisance pests.

A Quick Look at Their Life Cycle:

Adults may lay 300 eggs at a time, which hatch a week later into tiny, threadlike larvae. The larvae feed upon organic matter in the potting soil. After two weeks, they pupate into winged adults, that have no trouble annoying you to no end.

Basic Control Measures:

• The fastest and easiest method of control is to catch the flying adults with yellow sticky cards. The large cards can be cut into little strips and mounted onto little wooden splints (popsicle sticks) then placed around the base of the plant out of the line of sight.

• Water your potted plant from the bottom (sub-irrigation) by adding water to the saucer it is sitting in. This will keep the soil surface dry, making it uninhabitable for the hatching insect larvae. If the surface soil is already very wet, try placing a few potato discs or slices on the surface of the soil. This will attract the larvae as they migrate to the potato to feed. Simply replace the discs every three to four days with fresh slices to eliminate the next generation of adults.

• If you have a large number of plants afflicted as in a greenhouse situation, an application of predatory nematodes (Steinernema feltiae) as a soil drench is suggested. Nematodes will attack the fungus gnat larvae in the soil which will in turn lead to more nematodes being produced.

Good Bugs Are Working at Eising Greenhouse and Garden Centre!

Here at Eising’s Greenhouse and Garden Centre, we practice what as known as I.P.M. or Integrated Pest Management. Since we try to create a perfect environment for our plants, we also, unintentionally create perfect conditions for their related pests. To keep the pests at bay, we institute series of steps:

1 - Cultural Controls: We select only the healthiest of plant material to sell and keep them healthy through proper fertilization and growing conditions. We’ve learned that insects are attracted to stressed-out plants!

2 - Physical Controls: We are constantly walking through our plant aisles checking for insect and disease presence and removing the affected plants. Also a clean growing area means there is less chance of pest populations building up on alternate host plants such as weeds.

3 - Biological Controls: At the beginning of the growing season, even before there is any evidence of pest problems, we introduce naturally occurring predators into the growing areas. This is to be at the ready for when the pests do arrive!

In our arsenal we have a series of tiny parasitic wasps, microscopic wire-worms called nematodes, predatory mites as well as bacterial inoculants. So therefore, we cannot spray any chemical insecticides as they will hurt our very valuable biological cache!

Did you ever imagine all the behind-the-scenes work that goes into your plant purchases from Eising's to make them the best value around?

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.

Carried by Eising Garden Centre

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)

Carried by Eising Garden Centre

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!

Carried by Eising Garden Centre

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.

   We hope these tips help to ensure your healthiest lawn! For more information – and lawncare products - visit Eising Greenhouse and Garden Centre! 🌾

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!

Let’s get in depth about planting trees too deeply!

Sometimes homeowners find that their newly planted trees start showing signs of stress and become unthrifty a little while after planting, and soon their investment is altogether lost when the plant just dies. Often when we’re asked to inspect a tree in poor health, we know what to suspect.

   Although not readily apparent at the time of installation, the long-term effects of improperly placing the root system in the planting hole are substantial. The poor tree health that results manifests itself as reduced growth rate, atypical leaf size and colour, and increased disease susceptibility. Trees in really poor condition exhibit decay, cracks, and excessive deadwood. Sometimes trees show signs of stress within the first year of planting, but it usually takes several years for the problem to rear its ugly head.

   The most common reason? Many trees are simply buried too deeply causing the tree roots to decline in health, as they cannot get the vital oxygen from the air that they require to live.

Putting Down Roots

The width of the hole your tree will call home should be at least two times the diameter of the root ball, container, or in the case of bare root trees, the spread of the roots. This will provide the tree with enough worked earth for its root structure to establish itself.

   For tree roots to grow vigorously, they require water, oxygen, and warmth. An oxygen level of 25% of the soil volume is considered good for root development.

   At a 5% oxygen level, growth stops, and at 2%, roots decline and die.

   Since tree roots naturally grow quite shallowly in the soil profile, buried root systems are unable to obtain adequate soil oxygen and water. As a survival response, trees work to get roots closer to the soil surface where there is a more reliable source of both. The energy that a newly transplanted tree should use to overcome normal transplant stress is instead used just to survive.

   The tree expends its energy either by forcing its roots to grow upward or by creating totally new roots from dormant buds on the buried trunk, wasting all its prior growth. Some plants can survive being buried too deeply and live normal lives after developing a functional root system, others begin a long, slow decline of health resulting in either premature death or sudden failure during wind or ice storms. Let’s not risk it!

How Do I Know How Deep to Plant?

If you want your new tree to not only survive, but thrive, it needs the best start possible; it is very important that the root collar flare be visible after planting. The root collar is the part of a plant where the stem and root system meet, "flaring" where it transitions between the stem wood and the roots. Always make sure that the root collar flare is visible after planting. If settling occurs, reset the tree to the proper depth.

👉 Note: The backfilling soil should be a mixture of the original soil with composted manure or topsoil and bone meal.

But I Did Leave the Root Collar Visible… When I First Planted It

It has been observed that many times after a perfect tree planting, the homeowner then decides to build a raised-bed garden around the tree (thus burying the root collar flare – we’ve found root collar flares buried to 24 inches in mulch!) only to find that within a year or two, their young tree is dead or dying.

   A common practice, often referred to as ‘volcano mulching,’ also contributes to this problem. In addition to subjecting trees to the problems associated with planting too deeply, heat from the composting mulch can literally cook a tree's trunk.

So, What is ‘Planting Proud’ Then?

   The transplanting rules are amended if planting in the heavier clay soils where the practice of planting your new trees "proud" is advised. Planting proud essentially means that the root ball is left higher out of the ground level, producing a hilled effect. The soil that is normally used for back-filling is used to help to create a mound. Planting your trees this way in poorly draining clay soils prevents the ground water from collecting in an otherwise deep hole and drowning the roots of your new planting.

   But, as a general rule, trees should be transplanted no deeper than the soil in which they were originally grown, and the soil level shouldn’t rise after planting. Two to three inches of wood chips is the optimum depth to mulch - and keep it an inch or two away from the trunk. If it is really desired to have the tree as a focal point in this newly built garden, then possibly a 3 foot well could be made around the tree to keep the root collar flare open to the air.

   So, remember to give your tree a strong start and long life by not planting too deeply, but by leaving that root collar flare exposed!
