1 New potatoes will be ready for harvest after 10 weeks, usually in early July. 2  You should harvest all of your potatoes once the vines die (usually by late August), or the potatoes may rot.  Make sure you brush off any soil clinging to the potatoes, then store them in a cool, dry, dark place.
Maturity and variety also affect the texture of sweet potatoes. 4. Q. How do you know when sweet potatoes are mature and ready for harvesting? A. Sweet potatoes can be harvested at any stage of maturity. They require 100 to 140 days from planting to maturity depending on variety. Harvest sweet potatoes before the first killing frost because cool conditions can physiologically damage roots.
