Planting grass is typically an easy process when working on a level surface and all you have to do is seed the lawn and water it. Planting grass on an embankment, however, can be tricky as seed can easily wash down and out of the planting area. Rain and wind also contribute to the problem. To make grass grow on an embankment, follow proper preparations to keep the grass seed in place until it germinates.
Prepare your area for planting by raking the soil to loosen it and removing any rocks or debris.
Pour your grass seed into your broadcast spreader. Read the grass seed packaging to see the recommended seeding rate and set the dial on the spreader to the appropriate setting.
Push the broadcast spreader over the planting area and walk parallel paths to cover the entire area with seed.
Pour a starter fertilizer into the broadcast spreader and set the dial to the recommended rate on the fertilizer bag. Spread the fertilizer over the planting area.
Gently rake the soil with the garden rake to bury the seed in the top 1/8 inch of soil.
Spread a light covering of peat moss or straw over the planting area to prevent erosion of the seed and soil while you are waiting for germination.
Set up lawn sprinklers and water the grass lightly two or three times a day. The sprinklers should run about 5 to 10 minutes per watering. Adjust as necessary if the soil is staying too dry or getting too wet; each soil drains differently.
