When you select Bermudagrass as your turf grass, you should enjoy a beautifully green warm-season grass throughout the warm months of the year. Because Bermudagrass enters dormancy during the winter months, many gardeners opt to overseed Bermudagrass with a cool-season grass such as rye grass to ensure a green turf year-round. Prepare the seeding area thoroughly before overseeding the Bermudagrass and ensure you care for the germinating seeds properly.
Mow the Bermudagrass down to a depth of approximately 1 inch before overseeding.
Operate the core aerator over the entire area you will overseed to create core holes in the turf. These core holes will facilitate both air and moisture to penetrate the turf, which will aid in grass seed germination.
Fill the seed broadcaster with top soil and apply a 1-inch layer of top soil over the entire planting area.
Rake the top soil into existing grass gently with the garden rake to spread it thinly.
Pour the rye grass seeds into the seed broadcaster and set the broadcaster to apply the rye grass. Depending upon the thickness desired, apply between 5 and 15 lbs. of rye grass to every 1,000 square feet of planting area.
Push the seed broadcaster evenly over the area, overlapping the paths of the broadcaster by 4 to 6 inches to ensure even coverage.
Keep the seeded area evenly moist during germination by watering it with the garden hose or the sprinkler twice each day in the morning and evening. Apply water only to saturate the soil, but not to the point of creating puddles. After the grass germinates, gradually reduce the watering until the turf area receives only 1 inch of water per week.
Mow the overseeded grass for the first time when the rye grass is 2 inches high.
