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.

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.

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

Dealing with water restrictions or choosing to conserve water? You’re not alone. Many gardeners in Norfolk County are facing the challenge of keeping gardens thriving with less water. The good news? A lush, colourful garden is still within reach—thanks to drought-tolerant perennials.

When we think of drought-tolerant plants, cacti might be the first thing that comes to mind. But there’s a surprising variety of beautiful, hardy perennials that can handle our region’s dry spells—no desert landscape required.

While these plants do need regular watering when first planted, once established, they’re low-maintenance and well-suited to Southern Ontario’s climate, including periods of limited rainfall.

A Little TLC

It doesn’t take much to keep drought-tolerant plants thriving—just a little attention and some seasonal TLC. While they’re tough, even these hardy perennials appreciate an occasional deep watering during extended dry spells, especially in their first year.

For sun-loving perennials, skip the heavy fertilizers. Instead, an annual layer of compost is all they need to stay healthy and strong.

Shade-loving drought-tolerant plants, on the other hand, benefit from a layer of mulch. This helps retain moisture and reduces evaporation, especially in dry shade, which is one of the most challenging conditions for any plant to thrive in.

And don’t forget to deadhead regularly! Removing spent blooms encourages your plants to keep producing flowers instead of going to seed, meaning more colour, for longer.

With a few simple care tips, your drought-tolerant garden can remain beautiful and resilient throughout the entire season.

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.

During the dog days of summer, having a resilient, dependable, and beautiful perennial flower in your garden is terrific. Meet the Black-Eyed Susan. They are quick to establish and mature, and perfect for a perennial border, cutting garden, or naturalized garden. Depending on the variety, they will grow 1-3 feet tall and spread about 2 feet wide, making them a show-stopping spectacle!

If that and the cheerful, dark-centred, golden-yellow, daisy-shaped flowers aren’t enough to draw you in, here are more reasons we love these plants!

Long Blooming

Black-Eyed Susan (Latin name: Rudbeckia) is a prolific bloomer whose flowers can last from July to October. At a time in the season when many other flowers can look weary, Rudbeckia is a shining star. Its flowers grow on sturdy stems, which adds to their resilience.

Easy to Grow

Rudbeckia are robust! They are drought—and heat-tolerant and generally do well in hard-to-grow locations. Once established, they do not require frequent watering. Rudbeckia hirta is an Ontario native plant, and exceptionally hardy.

Plant Black-Eyed Susan in full sun to partial shade and almost any type of soil. They are adaptable, generally trouble-free and do not require any extra care.

Pollinator-friendly

We aren’t the only ones who love Rudbeckia; butterflies, birds and bees do, too. This makes Black-Eyed Susan a perfect partner for other pollinator-friendly plants like Monarda (aka Wild Bergamot and Bee Balm), Gaillardia (Blanket flower), Yarrow and Echinacea (aka Coneflower).

Who doesn’t love Black-Eyed Susans? Because of the course hairs on the stems, this is a plant that rabbits and deer don’t care for.

Black-Eyed Susan is perfect to grow in a border, bed, planter, or in a field as a mass planting. It’s resilient, attractive, low maintenance and a beneficial addition to any garden!
