Growing potatoes in 5gal buckets with straw?
I don't have much space to grow potatoes but have a few white 5gal buckets from the local grocer. I've read about a few methods to grow potatoes and wonder if I could fuse them together - I'd like to grow some fingerling or other small potatoes in these buckets (with drainage, soil, etc), starting with some high quality soil mix with plenty of compost and then layering straw on top of the plants up to the top of the bucket. I think potato plants are fairly attactive in flower so want the container for both the minimal footprint and also to be able to move the bucket into my beds as an ornamental once it flowers. Any insights on:
1) Is a 5 gal bucket even feasible or should I be considering something bigger?
2) How many sets can I plan in a 5 gallon bucket? How deep should the soil layer be?
3) Good varieties?
4) General approach to straw potatoes? What sort of soil should I be planting in?
