Every year Girl Far From Home plants sweet potatoes - well at least each of the last 3 years. The first year we got something like 40 potatoes but they were mostly small. The second year, I don't think we got anything at all. This year, we got four big potatoes and ten small ones.
We plant the potatoes in a large pot and then let the vines go anywhere but in Dad's grass (well, the first year they had the run of the yard but there was no grass thanks to the drought.) The first year, all the potatoes were growing on the vines and none in the pot. This year, there were four small ones growing in the ground off one vine, but all the rest were in the pot.
Time for Sweet Potato Dumplings - Yum!!!
