I used to always plant potatoes on Good Friday so I could harvest some by July 4th. Early frost doesn't bother them, if the top dies back a bit it will re-grow. Now I plant them around June 1. I found out that if I do that I'm not bothered by potato bugs. (not sure if you guys have them where you live) Here's a pic of the sweet potatoes about mid Sept. before harvest time, you can see they have over run everything, and the irish potato vines are nearly dead already.
This was my sweet potato harves last fall
Don't have many left, just enough to make some slips for next spring. These were Beauregard sweet potatoes.
