Ryegrass seeds are often broadcast on well-prepared lawns and watered on a regular basis to achieve germination. The seeds thrive well if covered with a thin layer of soil. You don't need to plant them in the soil.
Ryegrass seed requires soil contact to achieve the best germination. Clear or burn off the existing plants on the lawn where you want to plant the ryegrass seed. Before planting the seeds, test the soil to confirm the availability of all the necessary nutrients. Prepare the seedbed properly and mix the soil with the nutrients that are lacking.
Be very careful when broadcasting to avoid spreading the ryegrass seeds to unwanted regions. It is a waste to have ryegrass growing in flower gardens or paving areas.
