This summer we decided to grow sweet potatoes. It's a new crop for us, so we're learning as we go. They are out of control. They have gotten so huge they're out growing their raised bed. The vines just don't want to quit, and my husband doesn't want to cut them. He says he's fine with them moving out of the bed.
Here's my concern...
The canopy of the leaves, it seems, is making it impossible for the soil to dry up at all. Some of the vines that sit on the ground, where the roots dig, are rotting. My only idea is from the moisture of the soil. It has been raining every night, so we haven't needed to water. But this also means it's getting wetter and wetter. I try and go out and trim the leaves down, but there are so freaking many! And I don't even know if that's the problem.
Also, with him saying don't trim them back I'm worried the vine is going to concentrate all of it's energy on making vines and not potatoes. We had a tomato plant do this a couple years ago. The vines were up to 8 ft from the ground, and it hardly produced any fruit. DH was so impressed with the size he didn't want to trim that one either.
Advice? I can go take and post pictures if you'd like them.
