Unfortunately there are problems mixing the two grasses.
Overseeding bermuda grass with fescue.
Mow the existing lawn short says the nebraska extension.
But it does not do well in cooler weather and may need to be overseeded in the fall.
Also both types of grasses need nitrogen fertilizer but on completely.
It makes the summer lawn look lush.
With high quality fescue grass seed in hand it s time to move on to preparing the lawn.
Bermuda grass is a warm season grass that thrives in the heat of midsummer.
By then warm season bermuda usually has grown back thereby allowing homeowners with this turf mix to maintain green lawns all year round.
Ryegrass aside you can also overseed bermuda grass turfs with fescue grass varieties.
First bermuda likes to be mowed low and fescue likes to grow taller.
Some gardeners prefer to replace it with fescue a cool season grass that does best in the fall winter and spring.
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.
Cut to about 1 5 inches before overseeding so the new seedlings can compete with the existing grass and weeds.
Being a cool season grass fescue maintains its lush green color in all seasons except summer.
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.
