Taking care of your lawn in the Greater Toronto Area involves timing things right. Our climate presents unique challenges, from harsh winters to humid summers, but with the right schedule, you can maintain a lush, healthy lawn all year round.
Here's a simple month-by-month guide to help you keep your grass healthy and beautiful.
April: Wake-Up Time
As the snow melts and temperatures start climbing above 5°C consistently, it's time to assess the damage from winter. This is when you should:
- Rake up debris — remove dead leaves, twigs, and any matted grass
- Check for bare patches — identify areas that may need overseeding
- Stay off soggy ground — wait until the soil firms up before heavy foot traffic
- First light mowing — once grass reaches about 3 inches, give it a light trim at a higher setting
May: Growth Begins
May is when things really start to pick up in the GTA. The soil temperature reaches the ideal range for grass growth, and this is the best time to:
- Begin regular mowing — set your mower to 3 inches and mow weekly
- Apply spring fertilizer — a balanced slow-release fertilizer gives your lawn the nutrients it needs
- Overseed bare patches — the soil is warm enough for germination
- Start weed prevention — address dandelions and crabgrass early before they spread
June: Peak Season
By June, your lawn should be thriving. The key focus now is maintaining momentum:
- Mow regularly — twice a week during peak growth periods
- Water deeply but infrequently — aim for 1 inch per week, including rainfall
- Monitor for grubs — look for brown patches that lift easily, which indicate grub damage
- Edge your beds — keep a clean line between lawn and garden beds
July & August: Beat the Heat
The GTA summer can bring intense heat and humidity. Protect your lawn by:
- Raising your mowing height — taller grass retains moisture better
- Watering early morning — between 6-10 AM to reduce evaporation
- Avoiding fertilizing in extreme heat — this can burn your lawn
- Monitoring for chinch bugs — these pests thrive in hot, dry conditions
September: Recovery and Preparation
Fall is actually the best time for many lawn care tasks in the GTA:
- Aerate your lawn — this is the ideal month for core aeration
- Overseed generously — cool nights and warm days create perfect germination conditions
- Apply fall fertilizer — a phosphorus-rich blend promotes root growth
- Continue mowing — grass keeps growing well into October
October: Wind Down
As leaves start falling and growth slows:
- Keep leaves off the lawn — a thick layer of leaves can smother grass
- Lower mowing height gradually — bring it down to 2.5 inches for the final cuts
- Apply winterizer fertilizer — this strengthens roots for winter survival
- Final overseeding window — early October is your last chance
November: Winterize
Before the first snowfall:
- Final mow — one last cut at 2.5 inches
- Clean up all debris — leaves, branches, and any garden waste
- Put away equipment — drain fuel, sharpen blades, and store properly
- Protect sensitive areas — mark edges and garden features for snow removal
