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.

I'm wondering if the root system isn't big enough to support the green growth. Was the wilting less of an issue later in the season last year?

Hi Jeanie, Your suggestion seems correct, since I posted the same question in the vegetable garden web. The folks there have informed me that it is a normal phenomenum that some will wilt as it is a defense mechanism for conserving water. Perhaps when the root system grows more extensive, they will stop wilting. Last year I continued to keep them under some shade until harvest, and never thought to uncover them to see.
Thanks!
