Unfortunately there are problems mixing the two grasses.
Overseeding bermuda grass with fescue.
It makes the summer lawn look lush.
Also both types of grasses need nitrogen fertilizer but on completely.
When overseeding bermuda with fescue encourage aggressive fescue growth even into the warmer spring months by allowing shade from buildings or overhanging trees to cover the turf.
Cut to about 1 5 inches before overseeding so the new seedlings can compete with the existing grass and weeds.
Some gardeners prefer to replace it with fescue a cool season grass that does best in the fall winter and spring.
Ryegrass aside you can also overseed bermuda grass turfs with fescue grass varieties.
Sow 6 8 pounds of annual ryegrass per 1000 square feet and broadcast a complete lawn fertilizer than contains a slow release form of nitrogen if you have not done so already.
First bermuda likes to be mowed low and fescue likes to grow taller.
Prepare the lawn before seeding by mowing your bermuda grass about 1 inch and by raking the lawn vigorously with a metal tined rake.
Being a cool season grass fescue maintains its lush green color in all seasons except summer.
Prep the overseeding site.
But it does not do well in cooler weather and may need to be overseeded in the fall.
Bermuda grass is a warm season grass that thrives in the heat of midsummer.
Since bermuda grass is a warm season grass and fescue is a cool season grass the two seem like a match made in heaven.
