The ground can then be reseeded. Seed is preferred to sod because seed poses the least risk of reintroducing the fairy ring fungi. While total removal of fairy ring is not usually warranted due to the expense, some visual relief can be gained by masking. This is a process of applying fertilizer and watering deeply so that neglected or nutrient-deficient lawns will prosper. Good turf grass management practices can reduce the incidence of fairy ring and other diseases occurring in lawns.
Research shows that mowing high produces a denser grass with a greater volume of roots.
Mowing close reduces root masses and weakens turf. Clean sprinkler heads and adjust coverage patterns to get best watering results. Apply fertilizer in the beginning of April. Any lawn fertilizer will do. At the beginning of June apply a slow release fertilizer.
