10 Essential Fall Lawn Care Tips for Ontario Homeowners: From the GTA to Simcoe County

As the crisp autumn air settles over Ontario, from the bustling streets of the GTA to the serene landscapes of Simcoe County, it’s time to prepare your lawn for the coming winter. Fall lawn care is crucial in our region, where harsh winters can take a toll on unprepared grass. By following these essential tips, you’ll not only protect your lawn during the cold months but also set the stage for a lush, vibrant yard come spring.

At Black Swan Landscaping, we’ve been helping homeowners maintain beautiful lawns across the diverse landscapes of Southern Ontario for 6 years. Whether you’re tending to a compact yard in Vaughan or managing acres of grass in Barrie, these tips will help you make the most of the fall season and ensure your lawn stays healthy year-round.

1. Adjust Your Mowing Technique

As autumn progresses, it’s time to rethink your mowing strategy. In the GTA, where temperatures can fluctuate significantly in fall, gradually lower your mower blade. Start by reducing the height by about half an inch from your summer setting. For the final few mows of the season, cut your grass to about 2 to 2.5 inches high.

This shorter height helps prevent snow mold and discourages rodents from nesting in your lawn over winter. However, be careful not to cut too short, as this can stress the grass and leave it vulnerable to winter damage. In more northern areas like Simcoe County, where winters are typically harsher, you might want to leave the grass slightly longer (around 2.5 to 3 inches) for extra protection.

Remember, the key is gradual adjustment. Sudden changes in mowing height can shock your lawn, so ease into your winter length over several mowings.

2. Master the Art of Leaf Management

The colourful foliage of Ontario’s autumn is breathtaking, but those fallen leaves can spell trouble for your lawn if left unattended. In urban areas of the GTA, where trees are often in close proximity to lawns, regular leaf removal is crucial. In more spacious properties, like those in parts of Simcoe County, you might have more flexibility in your approach.

Here are three effective methods for managing fall leaves:

1. Mulching: For light leaf coverage, simply mow over the leaves to shred them into small pieces. These tiny leaf bits will decompose quickly, returning valuable nutrients to your soil. Many modern mowers have a mulching setting, making this task even easier.
2. Raking: When leaf coverage is heavy, raking is often necessary. In the GTA, where yard waste collection is common, rake leaves into piles for municipal pickup. In areas without this service, consider composting your leaves or using them as garden mulch.
3. Blowing: For larger properties or when dealing with wet leaves, a leaf blower can be a time-saver. However, be mindful of local noise ordinances and your neighbors when using power equipment.

Whichever method you choose, don’t let leaves sit on your lawn for extended periods. A thick layer of wet leaves can smother your grass, leading to dead patches and fungal diseases.

3. Fall Fertilization: Feeding Your Lawn for the Future

Contrary to what many homeowners believe, fall is actually the most crucial time to fertilize your lawn in Ontario. As grass growth slows above ground, the roots remain active, storing nutrients for the winter ahead and the spring to come.

In early fall, typically around September in the GTA and slightly earlier in Simcoe County, apply a slow-release, nitrogen-rich fertilizer. This will help your lawn recover from summer stress and strengthen roots before winter sets in. Around late October to early November, apply a second round of fertilizer, this time with a higher ratio of phosphorus and potassium. These nutrients are essential for root growth and winter hardiness.

When choosing a fertilizer, look for options specifically formulated for cool-season grasses common in Ontario, such as Kentucky bluegrass and fescues. The exact timing of fertilization can vary based on your specific location and the year’s weather patterns. In urban heat islands like downtown Toronto, you might fertilize slightly later than in cooler suburban or rural areas.

Remember, more is not always better when it comes to fertilizer. Over-application can lead to nutrient runoff, potentially harming local waterways. Always follow the product instructions and consider having your soil tested to determine its specific needs.

4. Aeration and Overseeding: Breathing New Life into Your Lawn

Fall is the perfect time for aeration and overseeding in Ontario. These processes help relieve soil compaction, improve drainage, and fill in bare or thin patches in your lawn.

In high-traffic areas common in GTA suburbs, aeration is particularly crucial. Use a core aerator to remove small plugs of soil from your lawn, allowing air, water, and nutrients to penetrate deeper into the root zone. For larger properties in Simcoe County, you might consider hiring a professional service with heavy-duty equipment for more efficient aeration.

After aerating, overseed your lawn with a grass seed mix suitable for Ontario’s climate. In shadier urban areas, choose a mix with more shade-tolerant varieties like fine fescues. For sunnier, open spaces common in rural areas, a mix heavy in Kentucky bluegrass might be more appropriate.

Water the newly seeded areas lightly but frequently until the new grass establishes. In the GTA, where fall temperatures can be milder, you might be able to overseed into early October. In Simcoe County, aim to complete this task by mid-September to give the new grass time to establish before winter.

5. Weed Control: Tackling Fall Invaders

While spring is often associated with weed control, fall is actually an excellent time to tackle persistent weeds in Ontario lawns. As weeds prepare for winter, they’re actively absorbing nutrients, making them more susceptible to herbicides.

Common fall weeds in Ontario include dandelions, clover, and thistle. In urban areas of the GTA, where lawns often border sidewalks and driveways, pay special attention to weeds in these warm edge zones. In more rural settings, be on the lookout for larger invasive plants like wild parsnip or giant hogweed.

For an eco-friendly approach, consider manual removal of weeds. This is particularly effective for smaller urban lawns. For larger properties, spot-treat weeds with a selective herbicide designed for fall application. Always follow local regulations regarding pesticide use – remember that many municipalities in Ontario have restrictions on cosmetic pesticides.

6. Adjust Your Watering Schedule

As temperatures cool and days shorten, your lawn’s watering needs change. In early fall, particularly during dry spells common in the GTA, continue to water deeply but less frequently than in summer. This encourages deeper root growth, making your lawn more resilient to winter stresses.

In Simcoe County and other areas prone to early frost, start tapering off watering in late September. Aim to water in the morning to allow the grass to dry before nightfall, reducing the risk of fungal diseases.

By late fall, usually around mid-October in southern Ontario, you can generally stop watering altogether. However, if you’ve recently seeded or laid sod, continue to water lightly until the ground freezes.

7. Tree and Shrub Care

Fall is an ideal time to care for the trees and shrubs that complement your lawn. In urban settings like the GTA, where space is often at a premium, proper tree care is crucial for maintaining a balanced landscape.

Prune deciduous trees and shrubs after they’ve gone dormant, typically in late fall. Remove dead, diseased, or crossing branches to promote healthy growth in the spring. In areas like Simcoe County, where winters can be harsh, avoid pruning after the first frost to prevent damage to the plants.

For young trees, especially in open areas prone to strong winds, consider wrapping the trunks with tree wrap to protect against winter sunscald and rodent damage.

8. Fall Planting: Setting the Stage for Spring

Contrary to popular belief, fall is an excellent time for planting in Ontario. The warm soil and cool air create ideal conditions for root development in many plants.

In the GTA, where fall temperatures often remain mild through October, you can plant spring-flowering bulbs like tulips and daffodils until the ground freezes. In Simcoe County, aim to get your bulbs in the ground by early October.

Fall is also a great time to plant deciduous trees and shrubs. The cooler temperatures reduce transplant shock, and the plants can focus on root development before winter dormancy. When choosing plants, opt for native species adapted to Ontario’s climate for the best long-term results.

9. Lawn Equipment Maintenance

As the mowing season winds down, it’s time to think about maintaining your lawn equipment. Proper care now will ensure your tools are ready to go when spring arrives.

For gas-powered equipment common in larger suburban and rural properties, run the engine until it’s out of fuel. This prevents the fuel from degrading over winter and potentially damaging the engine. For battery-powered tools popular in urban settings, ensure the batteries are fully charged before storing them in a cool, dry place.

Clean all your equipment thoroughly, removing grass clippings and dirt. Sharpen mower blades and pruning tools to ensure clean cuts next season. If you’re not comfortable doing this yourself, many garden centres and hardware stores in the GTA and Simcoe County offer tool sharpening services.

10. Prepare for Winter

Your final fall lawn care tasks should focus on preparing for winter. In the GTA, where snow cover can be inconsistent, avoid leaving any debris on the lawn that could smother the grass over winter. In Simcoe County, where snow cover is typically more reliable, focus on preventing snow mold by ensuring your final mow of the season is short enough.

If you use lawn ornaments or furniture, clean and store these items to prevent damage from freeze-thaw cycles. In areas prone to heavy snow, like parts of Simcoe County, mark the edges of your driveway and walkways to guide snow removal and prevent lawn damage.

Finally, drain and store hoses, and if you have an irrigation system, have it blown out by a professional to prevent freezing damage.
