wilting sweet potato plants
I have sweet potatoes plants from slips which I started this Spring. They look healthy and are full of leaves, but wilt whenever they get sunshine. This happened last year also (my first try ), and I have had to shield them from direct sun. Can anyone tell me why this is so. I thought they can take full sun to part shade. They are in a raised bed with sandy loam. Watering does not make any difference.
