Lawn Fertilization and Treatment questions, answered by experts

It’s not required, but it is helpful if your goal is to produce new growth. Any fertilization should occur after the lawn is aerated and before the compost is applied. If you also plan to spread seed, you’ll want to do so after the fertilizer is applied and once the ground is damp, but not wet.

Whether or not grass will fill in bare spots itself depends on the type of grass you have. For example, grass with rhizomes (e.g., Bermuda grass) and stolons (e.g., Saint Augustine grass) will naturally fill in bald spots as it spreads laterally. However, clump-forming grasses will not spread. 

Post-seeding care involves regular watering, mowing when appropriate, and occasional re-seeding to cover sparse areas.

You can use a fungicide to help control powdery mildew, but you should apply it judiciously as it can damage soil health and persist in the soil. Most of the time, proper watering, surface drying, and limiting shade can control powdery mildew without needing harsher interventions. If you have a repeated problem with powdery mildew, you can also try planting a shade-resistant type of grass that will be less susceptible to the fungus.

Sulfur is a secondary nutrient that helps grass grow lush and green. It combines  primary nutrients including nitrogen, phosphorus, and potassium. Sulfur helps the grass absorb nutrients to create a lush, green appearance. While sulfur isn’t necessary for every lawn, it can help most lawns be stronger and greener.
