Prof. Charles Hartman, Ph.D.Immediately seeding after aeration establishes the best situation for new grass establishment, as new holes serve as natural seed beds that provide cover against birds and wind. The moist soil plugs that form around seeds create ideal environments for germination. Prompt action on your part will result in quicker and thicker turf establishment.
Immediate Actions
- Spread seeds within 24 hours of aeration
- Use 50% more seed than bare soil rates
- Apply starter fertilizer immediately after seeding
- Lightly rake seeds into holes for coverage
Moisture Management
- Water lightly 3 times daily for first week
- Maintain consistent dampness without pooling
- Reduce to daily watering after germination
- Use sprinkler timer for consistent schedule
Long-Term Care
- Delay mowing until grass reaches 3 inches
- Apply slow-release fertilizer at 4 weeks
- Resume normal watering after 3 weeks
- Monitor for weeds and treat organically
Select grass types that are suitable for your climate and soil conditions. Cool-season grasses, such as fescue, establish most successfully when aerated in the fall. Warm-season grasses, such as Bermuda, will establish better when seeded in late spring. When selecting seed types, choose grass types that match the existing turf type to ensure even growth and appearance.
The correct method ensures that the seeds are in contact with the soil in the aeration holes. Use a broadcast spreader to distribute evenly as you walk in two different directions. Lightly rake after application to settle the seeds down into holes. Do not cover the seeds completely, as light is necessary to aid in germination.
Under ideal conditions, visible results are typically noticeable within 10 to 14 days. Initially, new grass appears in the aeration holes, providing a dotted pattern. Full coverage generally occurs between 4 and 6 weeks. If you wait to seed a bare spot, weeds will invade, significantly diminishing its effectiveness.
