Depending on where you live, RED ZONE can be planted anytime May through August. On the late summer plantings, make sure you plant at least 60 days before the 1st expected frost. Incidentally, we have had fantastic results “stagger” planting RED ZONE. For example, lets say I have a 2 acre field. We will plant a 1/2 acre RED ZONE in May, then another 1/2 acre of RED ZONE in June, another 1/2 acre in July, and the last 1/2 acre in August. In that 2 acre field, we will have 24 plants in all different stages of maturity.
