When to Fertilize Your Lawn in Southwest Ohio (By Season)

Timing is everything when it comes to growing a green, healthy lawn in Southwest Ohio. Between unpredictable spring weather and hot, dry summers, your grass needs just the right nutrients at the right time. That’s why following a seasonal fertilization schedule is so important.

Know Your Grass Type

Most lawns in this region consist of cool-season grasses like tall fescue, Kentucky bluegrass, and perennial ryegrass. These grasses thrive in the cooler temps of spring and fall, making those the most critical times to fertilize.

Your Ohio Fertilizer Schedule

Early Spring (March–April): As the soil warms to 55°F, it's time for your first feeding. This helps your lawn recover from winter and kickstarts green-up.
Late Spring (May–June): Apply a balanced fertilizer to support steady growth and strengthen the grass before summer heat sets in.
Early Summer (Optional): If your lawn shows signs of stress or thinning, a light summer feeding can help. Use a slow-release formula and water it in well.
Early Fall (September): After summer stress, fall fertilization is key. This is when your lawn is actively growing again and can best absorb nutrients.
Late Fall (October–November): This final feeding strengthens roots for winter and sets up a fast green-up next spring.

Fertilizer Best Practices

Before you fertilize, mow your lawn and make sure it’s dry. Spread fertilizer evenly and water lightly afterward to activate it. Avoid fertilizing before heavy rain, and always clean up excess product from sidewalks or driveways.
