pruning sweet potatoes ??
My sweet potatoes don't seem to be producing like last year, like only 20 or 30% as much. Last year we had rain and the lawn grew, therefore I mowed the lawn and kept the sweet potato bed cut to within the bed. This year, no rain and no mowing so the sweet potatoes are grown about 3 or 4 feet past the bed border. The potatoes that I have dug are fewer and smaller. could the fact that I am not pruning them back with the mower be reducing their output?
The vines look healthy and have been getting plenty water.
I did not dig last year til near frost and got a good crop.
Now that we have had rain I expect I will be mowing and wondering if I should trim the ends of the vines back, hopefully to increase production, any ideas?
