Introduction
Successful turfgrass establishment depends on rapid and uniform seed germination, particularly during the vulnerable early stages of growth. Mulch is commonly applied after seeding to conserve moisture, regulate soil temperature, protect against erosion, and enhance seed-to-soil contact, all of which contribute to better germination outcomes. However, not all mulches perform equally across different conditions and grass species. With the increasing availability of both traditional and innovative mulch products, turf managers, landscapers, and homeowners are faced with a growing array of choices. This field day demonstration evaluates the effectiveness of various mulch materials—ranging from straw to seed blankets and hydro-mulches. Seedling emergence, turf cover, and early growth quality will be discussed.
