The best time to overseed fescue grass is in the fall. The fall nights are cooler while the days are brief, allowing the ideal conditions for fescue seeds to grow. Fescue seeds are able to retain water in fall, and fescue seeds flourish without the harshness of the summer.
Why not Overseed in the spring?
Fescue is a cool season grass and will not grow at high temperatures in spring or summer. Fescue can be planted in spring, but will not reach the height it is meant to. Aeration, normally done in fall, should be done on a fescue lawn before overseeding. The aerating loosens the soil under the grass and makes it easier to overseed the fescue. Aeration should be done at the growing time for fescue which is fall.
Fescue lawns that are not overseeded can grow old and decay. Even if the lawn is mowed regularly, the grass will not be able to grow properly. The fescue will have trouble growing while competing with weeds and other lawn diseases. Excess grass on a lawn causes the healthy grass underneath to die. The excess grass is referred to as thatch. Thatch can be removed letting the grass underneath grow and sustain itself with nutrients without being blocked.
How to Overseed Fescue
Before applying fescue seed, aerate the lawn to release the soil to make it more accessible for planting fescue seeds. The new seeds will need to be applied with fertilizer to prevent the aerated holes from drying. Seeds will germinate quicker after fertilizing. Water the fescue once or twice a day until the grass begins to grow. Fescue seeds will need two weeks or more to sprout and begin growing. Mow the fescue until spring, when it grows slower.
