I planted an annual ryegrass last Fall on my Atlanta lawn for temporary winter coverage (the lawn was dirt & weeds before), which came up nicely, and was told that I'd have to overseed w/a more permanent grass in the Spring, which I'm about to do today, as the ryegrass would not survive the summer. The problem is that the ryegrass grows very fast and I'm afraid it will be 6 inches high before the new grass (Scott's new blend of tall fescue & heat tolerant Kentucky Bluegrass) has begun to germinate properly. I've mowed it pretty short to compensate for this but think it will probably need at least one more mowing before the new grass has even begun to germinate. Am afraid this will damage the new seedlings. Should I mow anyway when the rye gets high enough? Or should I wait until the new seedlings are the recommended 3" high or so (by which time the rye may be towering)?
