If you’ve lived in Mississauga long enough, you know our weather has a charming habit of doing whatever it wants. One minute you’re grilling on the patio, the next you’re staring out the window wondering why your lawn suddenly looks like it needs a wellness check. A proper lawn care schedule doesn’t just help your grass survive—it helps it look intentionally fabulous.
Below is a season-by-season Mississauga lawn scare schedule and guide to grass and lawn care that fits our local climate and helps you stay on top of key tasks like aeration, overseeding, weed control, and that ever-popular question: how often can I fertilize my lawn?
Spoiler: more often than you think—but only at the right times.
Early Spring (April)
Mississauga lawns wake up a little groggy after winter. This is the moment to set the tone for the year.
What to do:
- Spring Fertilizer
- One of the most common homeowner questions is when to fertilize lawn in spring Canada. The sweet spot is late April, once soil temps warm and the grass starts actively growing.
- Weed Prevention
- This is when weed control begins in Mississauga—especially if you want to get ahead of dandelions before they throw a backyard block party.
- Liquid Aeration
- Instead of traditional core aeration in the spring, liquid aeration is recommended. It loosens soil gently without disturbing fragile early growth and helps the lawn absorb nutrients more efficiently.
- Maintenance Tip:
- Rake any leftover winter debris and dead grass to prevent mold and encourage fresh growth. Start mowing lightly as soon as grass reaches 6–7 cm, keeping blades high to avoid stress.
Late Spring (May–June)
This is prime growing season, when your lawn is hungry and ready to fill out.
- Overseeding & Lawn Overseeding
- Spring overseeding helps lawns recover from winter thinning and patchy spots. Pairing overseeding with a liquid aeration gives seeds the perfect environment to germinate.
- Fertilizing Again
- If you’re wondering how often can I fertilize my lawn, most Mississauga lawns benefit from a second spring feeding around late may – early June.
- Maintenance Tip:
- Mow regularly, roughly once a week, and never remove more than one-third of the grass height at a time. Keep an eye out for uneven growth and adjust mower height as needed.
Summer (July–August)
This is the season when heat and dryness start running the show. Your lawn needs consistent support.
- Watering Wisely
- Aim for 1 inch of water per week—ideally early morning. Your lawn will take a faint bow in appreciation.
- Ongoing Weed Control
- Summer weeds are relentless. Regular weed control keeps them from overtaking thin areas or heat-stressed grass.
- Fertilizer (With Caution)
- You can fertilize early in the summer, but avoid feeding during extreme heatwaves. Your lawn has enough problems at that point.
- Maintenance Tip:
- Mow consistently, adjusting blade height to leave grass slightly taller during hot periods—this helps retain moisture and shade roots. Lightly rake fallen leaves to prevent smothering the lawn.
Early Fall (September–October)
If spring is about waking up the lawn, fall is about making it strong enough to face another winter.
- Core Aeration or Liquid Aeration
- Fall is prime time for core aeration, especially if paired with seeding. Only use core aeration in the fall if your soil is severely compacted or clay-based—otherwise, liquid aeration is just as effective – without exposing your lawn to more weeds.
- Overseeding
- This is peak season for lawn overseeding. Fall seedings germinate beautifully and thicken up your lawn for next year.
- Fertilizer
- Fall fertilizer is essential—think of it as sending your lawn into winter with a warm coat and a full lunchbox.
- Maintenance Tip:
- Continue regular mowing until growth slows, then lower mower blades slightly for the final cut. Rake leaves frequently to prevent mold and keep grass healthy.
Late Fall (November)
Time for the final touch-ups.
- Final Fertilizer
- If you missed an earlier application, early November still works—just make sure the ground hasn’t frozen yet.
- Last Weed Control Window
- Many homeowners don’t realize that fall weeds respond extremely well to treatment. The cooler weather makes herbicides more effective.
- Maintenance Tip:
- Do a final clean-up of leaves, branches, and debris. Avoid heavy foot traffic on the lawn as frost begins forming to prevent soil compaction.
