Rooting Sweet Potatoes

Two years ago I planted 9 sweet potato plants in an 8x9 foot bed. Eight plants flourished and yielded 52 pounds of sweet potatoes. I commented that was 52 pounds more than I buy in a year. And now, two years later, I still have some of those sweet potatoes in storage. This year I want to grow only two sweet potato plants.Just about all of my old sweet potatoes are sprouted. I selected four sweet potatoes that have healthy looking sprouts and I am going to try to root two good sweet potatoes plants from the sprouts and from two of the sweet potatoes. I am trying this both ways to see which way works best if they work at all. Both ways are described below.
The Two Ways
1. I broke the sprouts off two of the sweet potatoes, stripped the lower leaves, and placed them in a jar of water. Pictured on the right. -->
2. I cut two sweet potatoes in half and trimmed one side [to fit in container]. Then I placed each half in a tub of water. This method creates "sweet potato slips." Pictured below.
I have only one white sweet potato and it is pictured next to a red one in the tubs. [See the image below.] I do hope this method is a success because I want to grow one white sweet potato and one red sweet potato.
I am placing these in the kitchen window for now. A book that I have says to keep the sweet potato [the one that is in water] warm - 75 to 90 degrees F. My kitchen is warm enough.
I'm in no hurry. Sweet potatoes cannot be planted until the soil is consistently warm -- at least 70 degrees F [not the air, but the soil].
A side-note: Keep the sweet potato vines out of reach of your pets. Sweet potato vines are toxic if eaten.
Another side-note: The two ways described above are not the only two ways to propagate sweet potato plants.
Update: The sweet potato plants that grew from the sweet potato (the sweet potato slips) were more vigorous than the cuttings. I planted the sweet potato slips in the garden.

The Whole Blog
This morning, the tip on one of the sprouts looked withered, so I cut it off.
Later in the morning, I remembered to add a few drops of Sea Rich liquid foliar fertilizer to the water. Sea Rich contains fish solubles and liquid kelp and I buy Sea Rich from Gardens Alive!
Cool. I have heard about trash can potatoes. Have you heard of that? I could only do it with white potatoes because I am the only one that likes sweet potatoes.
I have heard about that, but I’ve not tried it. I grew a potato plant in a spare tire once twenty-something years ago. It was a grocery store potato and it made a plant and a few little spuds. =) I didn’t take care of it or it might have made a few medium-sized spuds. =)
