Growing them for the first time in Georgia. About 30 plants, adequately spaced. Most are are about 6" in height. Recent hard rain has about half of them beat down, the rest are still upright. Will these ever regain rigidity on their own and stand back up? Can I put a splint in the ground and tie them up? They are healthy and growing, but on the ground. There is a field in my area of about 5 acres full of sunflowers every year. What does he do? I know he not out there splinting up his plants. Thank you for reading and any advice!
