Up to you just let me know. No worries rooted or unrooted if so. Sweet potato is easy to root like you said in water.
When I eat the greens they are usually well cooked first. Never tried any in mass very fresh due to the white sap just in case though I know they are safe. Often cooked them into sauteed mixed greens or curries etc.
Got a fresh hugel mound to experiment with this season. Did very well with sweet potato in the past in hugel or
compost gardens. Gonna plant lots of random stuff into the mounds. Put a few Seminole pumpkin, yard long bean, and pigeon pea around the edges. Other things will find its way in there soon too!
