Any fertilizer that complies with the MD lawn fertilizer law and recommended fertilization schedule should be fine. Extension doesn't compile brand information, and we do not recommend particular brands.

As your lawn is newly established, the best way to add soil conditioners is to return grass clippings to the soil surface for composting by mulch-mowing.This will improve soil organic matter content over time. You can't really top-dress an established lawn. Any added compost would have to be considered for the yearly maximum nutrient supplementation.

Thank you for your question.
