It is rich in organic matter, which helps retain moisture and provides food for beneficial microorganisms. Apply a layer of compost to your lawn, about 2-4 inches deep, before planting the grass seed.
Fertilizer
Fertilizer is used to supplement the soil with specific nutrients. Choose a fertilizer specifically designed for lawns and follow the instructions on the package. Apply the fertilizer evenly to your lawn before planting the grass seed.
Timing
The best time to amend the soil is in the fall or early spring, before planting the grass seed. This allows the amendments to break down and incorporate into the soil before the grass starts to grow.
Removing Existing Vegetation and Debris
Before planting grass seed, it’s essential to remove any existing vegetation and debris from the lawn. This includes weeds, existing grass, and any other material that might hinder the growth of the new grass.
Tools
Several tools can be used to remove existing vegetation and debris. A shovel, rake, and dethatcher are all effective tools for this task.
Steps
1. Remove weeds
Use a weed killer or manually pull out any weeds before planting the grass seed.
2. Dethatch
If your lawn has a thick layer of thatch, use a dethatcher to remove it. Thatch is a layer of dead grass and other organic matter that can prevent water and nutrients from reaching the soil.
3. Rake
Once you have removed the weeds and thatch, rake the lawn to remove any remaining debris.
The best time to plant grass seed for a lawn that stays green year-round depends on your climate. In most areas, the ideal time is in the early fall, as the soil is still warm but the weather is cooler, promoting germination.
