Q.Sweet Potato Slips
I am attempting to start my own sweet potato slip from last year’s crop. I am using a heavy tin foil container and put it about three to four inches deep with Miracle Grow potting soil. Placed my potatoes on top of that and then covered with more soil. It has been three weeks and I have nothing. How long does it take to set on slips?
