When can I cut tall fescue after seeding?
Wait until the new grass has reached a height of four and a half inches and only cut it down to three and a half inches at the lowest. Taking off too much of the grass blade at once is very stressful to a mature fescue plant, so it's especially taxing and potentially fatal to newly developed grass.28 sept 2018
