I planted in southern ok at the beginning of the month, they are doing fine but have gotten some good rain since planting. I wouldn’t plant unless there is some rain in the forecast. But as STX said, size of plot is going to be critical. I would do no smaller than 2-3 acres and more if possible. Deer will find them and eat them and graze down a small plot pretty quick. I have 4 one acre plots and they are all nipped to ankle height, so next year I will plant bigger plots (was my first year doing spring/summer plots).
