Renovation of Cool Season Turf
Sometimes, when evaluating turf areas, the best strategy can be to totally renovate existing turf due to the amount of undesirable vegetation, such as bermuda grass, nutsedge and/or extensive weed infestations. First it is important to eliminate this undesirable vegetation. To allow adequate time to eliminate this undesirable vegetation before the optimum seeding time in September, this process should begin in mid-July.
The renovation process of an existing lawn would be similar to the process of overseeding with the addition of one step. Before the seeding process begins, the area needs to be mowed as low as possible to remove any dead debris.
