How high is too high? How low is too low?
Mowing your lawn at the right height is important. Generally the higher you leave your grass, the better it is for it. Leaving your grass high keeps many of the important nutrients on the plant and protects it from hot weather. Cutting it at 3 or 3.5 inches is the optimal height for grass in Loveland Colorado, which is mostly bluegrass or fescue.
However, the shorter the grass is, the more pleasing it is to the eye. A good comprimise is 2.5 inches if your grass is healthy. If it’s not looking so good, better to stick with the longer grass height at 3 or 3.5 inches.
