    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?

    1) if it were dormant you wouldn't be cutting it
    2) higher cut = better drought tolerance .... but you already knew that.

    My 2 cents: even if lawns are in full drought you still have to mow them every 2-3 weeks to knock 'the rough' off. Otherwise they really look like junk. And there will be trimming to do. I stay mowing at 3" regardless. No way I could cut anyone's lawn 4" tall, to me that looks like unkept hairdo. If your gonna mow, you have to balance proper cut height with aesthetics and to me 3" is it.

    I cut 3.5" all year round except for the last cut of the year which I'll drop it down to 3", I skipped a few last week. And this week I'm skipping all of them & probly next week too. Then I'll go out the following week and clean em all up, and then probly skip again. We are supposed to get some rain this week, but even that won't do much. Never seen lawns so brown before! Lol

    Well, yes and no. I suppose there has to be some growth for the tops to become uneven, that is just common sense, but over most of the lawns, the visible portion of the fescue blades are brown. I agree that a higher cutting height probably helps "shade" the ground to some extent, but 3 1/2 is still not exactly short, and I wouldn't even consider going any lower.

    In the case of lawns being mixed with bermuda, the bermuda is growing more than the other grasses at this point, and just doesn't look right mowed a full 4 inches.

    1) If it dormant it is not growing
    2) Higher cut = better drought tolerance ..... didn't say anything about better water conservation
