Maintaining a lush, green lawn isn’t just about frequent mowing or watering — it's about feeding your grass at the right times of year. In Niagara, where our seasons are distinct and weather conditions can shift rapidly, fertilizing in both spring and fall is essential to keep your lawn healthy and resilient year-round.
Why Focus on Spring and Fall for Lawn Fertilizer?
Grass doesn’t grow consistently throughout the year. It has growth spurts — primarily in spring and fall — when temperatures are moderate and soil conditions are just right. Applying fertilizer during these peak times gives your lawn the nutrients it needs when it’s most ready to absorb and use them.
Let’s break it down by season.
Spring Fertilizing: Wake Your Lawn Up Right
After a long, cold Niagara winter, your lawn is tired. Snow, ice, and freezing temperatures take a toll. Fertilizing in early to mid-spring (typically late April to early May in Niagara) helps:
Kickstart growth after dormancy
Replenish nutrients lost over the winter
Promote a strong root system early in the season
Thicken turf to crowd out weeds before they get established
Fall Fertilizing: The Secret to a Strong Lawn Next Year
Many homeowners overlook fall fertilizing, but it’s arguably just as or more important than spring. In Niagara, based on how the seasons have gone in a particular year, late September to early November can be an ideal window for a fall application. Here's why fall fertilizing is crucial:
Strengthens roots before winter dormancy
Improves disease resistance and overall hardiness
Promotes early spring green-up without a growth surge
Stores nutrients for a stronger comeback next year
Why This Matters More in Niagara
Niagara’s unique microclimate — influenced by Lake Ontario and the Niagara Escarpment — means we experience:
Long winters with freeze-thaw cycles
Humid summers that encourage weeds and lawn diseases
Variable soil quality, especially in older neighbourhoods
Fertilizing in spring and fall helps combat these challenges, ensuring your lawn stays thick, green, and healthy despite the region’s ups and downs. Proper nutrition allows grass to outcompete weeds, recover from seasonal stress, and handle drought better in summer.
