Ladies and gentlemen, start your sweets!
How to start sweet potatoes
Last year I had good success with starting and growing my own sweet potatoes (which I served for Thanksgiving dinner!). I started them in the traditional way, show in the photo above. Take a sweet potato, put four toothpicks in it (perpendicular to the potato), suspend the rounder end in a jar of water, and put in a sunny window. When the sprouts (called slips) are about 6 inches long, you can either cut them from the plant and directly plant them into the garden, 2 weeks after last frost (they need really warm soil, as the are a tropical vine) or you can pot them up and let the roots form.
I am also going to try another method this year- split a sweet potato in half lengthwise and bury it, cut side down, under some light soil in a plant flat, under light on a heat mat. This way the roots will form well and the slips should be well rooted. The time to do this, in order to plant at the end of April/beginning of May, is NOW! You can use sweet potatoes from the grocery, though might want to order or buy certified disease-free potatoes or even the slips themselves from a nursery.
