Mowing Matters: How your mowing practices may be causing problems with your lawn
One of the most important things you can do to help keep your grass thicker and greener while minimizing weeds and fungal diseases during the stress of summer is to mow it at its proper height. The proper height for Fescue is 3″-3.5″. The only times we recommend cutting it lower is the first time you mow in late winter and just before your fall renovation. A little shorter in the spring and fall when temperatures are consistently below 80 degrees is probably ok, but not too low or you may be compromising root growth during critical periods when your turf needs to build its strength. When daytime temperatures start flirting with the 80 degree mark, it is time to raise up the mower deck.
- It shades the soil from the sun, which keeps your grass’s roots moist longer.
- The shaded soil also prevents some weed seeds from germinating and sprouting. In our experience, homeowners who mow their lawns lower than 3 inches usually have more weed problems.
- Cutting Fescue higher reduces the stress on the turfgrass plant, which makes it less susceptible to fungal disease and drought stress.
- Keeping the grass higher, allows the turfgrass plant to focus its energy on growing deeper, stronger roots rather than on recovering from close cutting.
