I am hoping to grow all of my own sweet potato plants this year. In the picture above, you can see four glass jars, filled with water, each with a sweet potato in it. Over the next few weeks, sweet potato "slips" will grow and when they are big enough, I will pull them off and put them in a jar of water. They will grow roots and then in May, I can plant them outside.
I chose one of the purple sweet potatoes and three of the regular ones that have little sprouts growing out of them already. You can see, in the pictures, the sweet little slips growing out. I put them in the water just last night and the leaves are already starting to open!
As they grow, and I pull them off, they will grow more. I am looking forward to getting into the garden this Spring. I still have the kale out there and there are bunching onions and garlic growing a little.
