I did alot of potatoes in 30 gallon root pouch bags last year. Covered in potting soil and then munched with straw. No good. I didn't get many potatoes compared with in ground. Those bags get really dry especially towards the outsides. I read you can bury them in the ground but then why use the bags? Too much work. I have two pots only this year because I had so many leftover seed potatoes. My main plot is a raised bed made by straw bales as the outside. This works well. Grows good potatoes. Also the end of June is quite late to start potatoes they are a cool weather crop. I started mine late I think beginning of April. I am growing Yukon gold Yukon gem purple majesty and a red one I think is desierre or something. Labels are buried. I hill them with dirt and then mulch them thickly with straw. One year I just covered with straw and the mice voles and rats got most of them. Good luck!
