This is great! How long to have slips ready to plant from setting sweet potato in water?
We start ours in April about a month ahead of planting. You can start them about anytime and just trim the roots if they start packing the jar. Add a drop of miracle grow or some kind of hydroponic fertilizer occasionally to keep them green and growing. Sweet potatoes are amazingly resilient. I found a bag of small ones we saved from the garden last year in the garage all dried up. We applied the jar rooting method and got about 80% starts after a winter in the garage!
