Fall and spring are the best seasons to reseed your lawn or fill in bare or weak lawn areas. Before you reseed, if the ground is too dry and difficult to be penetrated, water the lawn a few days in advance of the laying the seeds down. It is important to keep the seeds moist until they seed. Then water every few days until sprouts a about 1 1/2 high.
When you reseed, consider using an all purpose fertilizer at the same time. One brand, Milorganite 6-2- 0, is a product that uses organic nitrogen as the base. It’s safe for turf and plants. Plus, it doesn’t burn!
