Step 3 · Determine Optimal Application Time

Fertilize when your lawn is actively growing. For cool-season grasses (like fescue, ryegrass, bluegrass), the best times are typically early spring and fall. For warm-season grasses (like Bermuda, zoysia, St. Augustine), late spring and summer are ideal. Avoid fertilizing during extreme heat waves or when the grass is dormant. Ensure the grass is dry to prevent fertilizer from sticking to blades and causing burns, and to allow for even distribution.
