My experience growing potatoes has been pretty cool. I bought a pack of 6 and planted them 60+ days ago and this is what I learned. They should have space, I may have spaced them together too much. I see some spots on the leaves and I used some neem oil try and correct it. That burned some of the leaves and I was somewhat discouraged. I was contemplating starting getting rid of the potato plants and I pulled up one of the shish kabob sticks from the ground and a potato was stuck on the bottom of it… lol. So what I thought was a failure for my first time planting potatoes was actually better. The potatoes are Red Norland Potatoes. 

I left the other plants in the ground but I will probably pull them up in a week or so.
