your problem is related to 2 things
1. variety of potato you grow
2. soil minerals available
re variety have you tried growing heirloom ? try seeds of change and get some of their potatoes. try a few dif varieties till one clicks for you.
re mineral bugs will attack your plants if deficient in minerals... know what rock dust is?


I have already tried 4 different kinds of Potatoes. I have no idea where to get potatoes other than those sold in stores. Never heard of Heirloom? Seeds of change is that on the web? Store?
I had my soil tested=Good.
I don't know what rock dust is.
Farmers around here have been planting potatoes for 45 years. They all have huge infestations problems. I pulled all my plants last year and brought them to the dump. I had 3 different kinds planted .When I saw the infestation that occurred in only 2 weeks and I had tried everything I could I gave up. Help-Frustrated Tara
