I picked up a bag of russet seed potatoes from Wal Mart and proceeded to let them sit in my garage for a few weeks. They were looking quite rotten when I cut and planted 4 in late June (really late for SC). I harvested almost exclusively little “new potatoes”, some of which you can see in my pic of the sweet potatoes.
I ordered the sweet potato slips a little late as well (early June) and waited two days to plant them, so only 2 survived. But I planned to let them grow until the first frost, which unfortunately hit earlier this week.
I will definitely plan much better next year and get both types planted as soon after the first frost as possible.
And until I can get my garden area set up the way I really want it, I’m giving up on corn, onions, carrots, etc. I’ll stick with tomatoes, potatoes and maybe some peppers.
Do you mean "first" frost, or "last" frost? Are you plannting potatoes in the spring, or the fall?
