In my area, the predominant cool season grass in lawns is usually fescue of some sort. Along with a good assortment of weeds, often including crabgrass, many have bermuda in the mix, and a few of my accounts are predominantly bermuda, or at least have areas that are predominantly bermuda. I start the mowing season cutting at least 3 inches on all properties, and on some of the rougher ones, as high as 3 1/2. As the weather warms, and it begins to dry out, I raise to at least 3 3/4 and on most properties, go a full 4 inches. Now, with the drought worsening, and being more prolonged, I find that trying to cut on 4 inches leaves a very shabby appearance. Mostly, I'm cutting weeds, and in some cases, bermuda, but only the occasional green stem of fescue. I tried dropping back down to 3 1/2 inches, and found the finished look to be much better. My thinking is the fescue is basically dormant anyway, so cutting it a bit shorter isn't going to hurt, and bermuda could probably be cut even shorter without hurting it. Is my thinking flawed?
