Here's why:
* Germination: Grass seeds need light to germinate. If you plant them too deep, they won't get enough light and won't sprout.
* Root Development: As the seed sprouts, the roots will grow down into the soil. Planting on top allows the roots to easily find their way down.
* Moisture: Seeds need moisture to germinate. Planting on top allows the soil to retain moisture more effectively.
How deep should you plant grass seeds?
The ideal depth is about 1/4 inch. You can use a rake or a seed spreader to ensure even distribution. After planting, water the seeds lightly to keep them moist.
