Before taking steps to repair your lawn, identify and correct any major issues that might be affecting your lawn health. This might include:
- pruning trees and shrubs to allow more sunlight to reach the grass
- aerating your lawn to improve soil compaction
- dethatching your lawn to remove the dead, compacted grass, or thatch.
Seeding your lawn should be done as soon as possible in spring once snow and ice have melted. Use a rake, dethatching machine or tiller to lightly loosen the soil surface. If an entire area is dead grass or weeds, rake or till a bit deeper. It’s best to have about a ¼ - ½ inch of loose surface soil so that the seed is well incorporated and can take root.
- Overseed your lawn with about 1 - 3 pounds of seed per 1,000 square feet (depending on how sparse the grass is).
- Consider adding a bit of topsoil in extremely sparse areas.
- It’s best to use a push spreader for large areas to ensure even distribution of seed.
- Once your seed is spread, lightly rake it into the soil and add roughly ½ inch of water.
- For the next few weeks, as your lawn is getting established, water it daily (unless there is sufficient rainfall) to keep your lawn surface slightly damp.
- As the lawn continues to establish you can water it less frequently but for a longer time.
- Do not mow until your new grass is roughly 2 – 3 inches tall.
