The Ultimate Lawn Care Calendar for Mississauga Homeowners

Keeping a lush, green lawn in Mississauga takes a bit of planning and care throughout the year. The key to a healthy lawn? Doing the right tasks at the right time. That’s why we created this Ultimate Lawn Care Calendar, tailored specifically for Mississauga’s climate and soil conditions.

Follow this month-by-month guide to keep your grass thick, green, and resilient — whether you’re a DIY enthusiast or want to know when to call in the pros at Smiling Lawn.

January – February: Winter Lawn Care

• What to do: Mostly rest and protect your lawn from heavy foot traffic and ice damage.

• Tips: Avoid piling snow on the grass, and keep pathways clear of ice to prevent compaction and damage.

• Why: Grass is dormant during winter, but heavy traffic and freeze-thaw cycles can cause stress and bare patches come spring.

March: Early Spring Prep

• What to do: Start cleaning up your lawn by removing leaves, sticks, and debris.

• Tips: If soil is dry enough, rake lightly to remove dead grass and thatch buildup.

• Why: Preparing the lawn early helps new grass breathe and grow well when it wakes up.

April: Soil Testing & Fertilizing

• What to do: Test your soil’s pH and nutrient levels (you can use a home test kit or hire a pro).

• Tips: Based on test results, apply a balanced fertilizer tailored for cool-season grasses.

• Why: Fertilizing in early spring kick-starts growth and prepares your lawn for the growing season.

May: Over-seeding & Weed Control

• What to do: Overseed thin or patchy areas to fill in bare spots.

• Tips: Apply pre-emergent weed control early in the month to prevent crabgrass and other weeds.

• Why: Early seeding takes advantage of warming soil, and weed prevention keeps your lawn healthy and weed-free.

June: Mowing & Watering

• What to do: Maintain regular mowing (around 2.5 to 3 inches tall) and water deeply but infrequently.

• Tips: Avoid cutting more than one-third of the grass blade at once to prevent stress.

• Why: Proper mowing and watering encourage strong roots and reduce disease risk during warm weather.

July: Aeration & Pest Monitoring

• What to do: Check for signs of lawn pests and disease, and plan for aeration if your soil is compacted.

• Tips: Aerate if you notice water pooling or hard soil (best done late summer or early fall).

• Why: Aeration improves nutrient and water absorption and helps your lawn survive hot, dry spells.

August: Summer Care & Drought Management

• What to do: Water your lawn early in the morning to reduce evaporation and stress.

• Tips: Avoid heavy fertilization in high heat — focus on keeping your lawn hydrated.

• Why: Mississauga summers can be hot and dry, so proper watering is essential to prevent browning.

September: Fall Fertilizing & Seeding

• What to do: Apply a high-phosphorus fertilizer to encourage root growth and overseed bare areas.

• Tips: Aerate your lawn before seeding for best results.

• Why: Fall is the ideal time for lawn repair and preparing your grass to survive the winter.

October: Leaf Cleanup & Final Mowing

• What to do: Regularly remove fallen leaves to prevent mold and disease.

• Tips: Gradually lower mowing height to about 2 inches before the last cut.

• Why: Clean, short grass going into winter reduces disease risk and promotes healthy spring growth.

November – December: Lawn Rest & Equipment Maintenance

• What to do: Give your lawn a break as it goes dormant.

• Tips: Use this time to service your lawn mower and prepare equipment for next year.

• Why: Proper maintenance of tools saves time and money when the busy season returns.
