Whether you’ve got a small bare patch or half a lawn to reseed, it’s best to do it in the late
summer or fall, when cool temperatures will give the grass a good start.
1. Rake off any dead grass and debris.
Loosen the soil in the bare patch to a depth of 1 inch (2.5 cm). If the grass was killed by dog urine or a chemical spill, douse the area thoroughly with water several times to dilute the harmful chemicals.
2. Level your compost.
Spread 2 to 3 inches (5 to 7.6 cm) of compost over the area, then smooth it with the back of a rake so the compost is level with the surrounding soil.
3. Mix the seed with an equal amount of damp sand a day before you sow it.
The moisture will jump-start the process of germination. Scatter the seeds evenly with the sand; that way, they’ll stay in place on the ground, even on a windy day.
4. Cover but don’t wash away.
Cover the seeds with a thin layer of compost, then water the area gently, being careful not to wash the seeds away.
5. Keep the area moist.
Use a fine spray of water two or three times a day until the seeds germinate, then water regularly along with the rest of your lawn.
