Q: Can I mix tall fescue with my Bermuda?

While the new tall fescue grass types have many exceptional qualities, I wouldn't recommend combining the two. Fescues are what are called a bunching-type grass, that is, they grow from one central mass. To create an attractive lawn with the fine fescues, it needs to be closely planted to form an even grass. Bermuda spreads via both rhizomes and stolons which creates for a very thick mat of turf. The fescue, if it gets established will stand out as small clumps among the Bermuda. Also, highbred Bermuda is usually cut slightly lower, anywhere from 1/2" to 1-1/2" and the fescue is 1-1/2" to 2-1/2".

Bermuda has a slightly higher resistance to drought conditions than the tall fescue, but one of the advantages of the tall fescue is it's higher resistance to drought conditions compared to bluegrasses. Bottom line: don't mix the two. Go one or the other. If you decide to go with the tall fescue, you'll need a complete lawn renovation. Tall fescue would be well suited to New Jersey, better so than Bermuda. Hope this helps.
