Terri, I used to always plant potatoes around Good Friday as then I could harvest some around the 4th of July. However, I have now learned that if I wait until June 1, I miss the whole potato bug problem, and I still get a good crop of potatoes. I live North of you! It seems that by planting them later you don't have to deal with them at all. No chemicals needed. I ususally plant Red Pontiac and Yukon Golds.
