I have been so excited to harvest my sweet potatoes. I discovered that the best time is four weeks after the first flower blooms. The first flower bloomed about June 5th, so July 4th seemed like the perfect day! I was thrilled to get some big ones! All the tiny little ones were from the slip re-rooting and making more. Next year I will plant three or four rows of slips. I’m thinking I will make some sweet potato fries!
