How long does it take for sweet potatos before harvest? I used to grow them in Florida were there was not much worry about growing season. Now I ive in Colorado.
There are various times depending on the variety. I think I used 90 day, but there are 100 day and 120 day varieties as well. But you can also let them go longer to get bigger or more potatoes.
I started my own plants in a plastic glass after Christmas last year, planted the slips in a half, plastic barrel when the threat of frost was over. Harvested today.
