Cut your grass longer it is actually healthier for your lawn. Cut your grass to a height that is commonly recommended for the type of grass you have. 2.5 - 3 inches is recommended for Kentucky Blue Grass. Never scalp or crew cut your lawn. A lawn cut high discourages weed and insect infestations.
Longer grass is hardier and much more competitive.
It also helps prevent weeds from sprouting, keeps the roots and soil moist and will encourage the roots to grow deeper into the soil. Cutting longer aids the Mycorrhizal process you are establishing, and both aid your lawn in resisting lawn diseases. Keep the blades on your mower sharpened so you don t rip the grass. Make sure the grass is dry when you mow it. Earthworm populations in BioVam lawns explode and feed on that mulch.
