Water the lawn deeply and infrequently, irrigating the grass only when soil 2 inches below the surface feels dry to the touch. Moisten the top 6 to 8 inches of soil each time you irrigate. Water the lawn in early morning, if possible. Fertilize the lawn every six to eight weeks when the grass is actively growing, or about four times each year by broadcasting a slow-release, balanced fertilizer over the grass at a rate no greater than 1 pound of nitrogen per 1, square feet of lawn with each application.
Providing the turfgrass with sufficient nitrogen often greatly reduces the occurrence of red thread. Prune off overhanging and adjacent tree and shrub branches selectively to reduce shading and improve air circulation around the grass. Dethatch the lawn in late spring or early fall and only when there are still at least 30 to 45 days left in the growing season to give the turf sufficient time to recover from this injurious process. Rake up and dispose of the loosened debris.
