Over seeding.

Why fall is best season to reseed your lawn?

The fall allows grasses to establish before winter sets in. Two months before the first frost is the best time. Fewer weeds and fewer active lawn diseases occur during the fall therefore your grass will not have to compete for access to sun and water. Sunlight begins to increase during fall as the tree leaves begin to drop. Healthy lawns require a lot of moisture, making spring the second most popular (but less ideal) season for seeding. 605-376-1696.
