What is good to interplant with sweet potatoes?
Tall stuff -- like okra. Sweet potatoes, squash, and peanuts fall into the spreading ground cover group, so okra can go well with all three. I wouldn't recommend corn though. I never have gotten the hang of planting a three sisters garden exactly right, where the corn provides the poles for the beans, and the squash ground cover provides a living mulch. Sometimes there is so much corn that it shades out the squash, other times there is not
enough and the beans don't have enough poles to climb. I haven't had those kind of problems with okra, it doesn't seem to provide so much of a
canopy that things have a hard time spreading under it.
