The best time to fertilize your lawn is in the spring, when the soil temperature reaches 55 degrees Fahrenheit. You'll know when the soil warms up to 55 because the lilacs begin to blossom and the grass starts growing. For most parts of the country, that means the first feeding should take place by about mid-April.

When should I apply fall fertilizer?

Apply fall lawn fertilizer 2 to 3 weeks before the ground freezes. To find an exact date, look for the first frost date in your area. That date is typically a good time to fertilize since the ground hasn't frozen yet. More generally, mid-October is a good time to apply lawn fertilizer.
