WEST LAFAYETTE – Many homeowners with drought-damaged lawns have some decision to make about how to repair them. Aaron Patton, a Purdue turf grass extension specialist, says it mostly comes down to whether to fertilize or to re-seed.
Most grass species in Indiana are cool-season grasses. The hot weather over the summer either heavily damaged or killed those species.
The answer to whether to fertilize or to reseed depends on the size of the damaged area. If the damaged area is larger than the palm of your hand, the best bet is to re-seed. If you’re going to fertilize, look for a label that has a high percentage of nitrogen.
If you’re reseeding, avoid seed that establishes itself quickly. Those seeds have a lot of annual ryegrass which is not cold-hardy or tolerant of heat and drought.
