You can grow anything in a container if you go about it the right way!!

I'd check out potato grow bags. These are a lightweight woven plastic container, tall enough to allow layering the soil as one should do with potatoes as they grow to increase tuber production and with access panels at the base to make harvesting easy without overly disturbing the plants.

These are inexpensive and last for several seasons. And you can grow any kind of taters in them :-))

Also called Smart Pots, these are available for a variety of different edibles, including strawberries and tomatoes.

I've heard that before. I don't want to spend money on them now. Someone gave me some huge nursery pots I want to use. I think they are 15 or 20 gallon pots.

I've grown potatoes in containers of 20 to 45-gallons, including smart pots and rubbermade totes. I didn't get a large yield, but it was fun. I had best results growing no more than one seed potato per 4 gallons of potting mix. Five red seed potatoes totaling about one pound in a 20-gallon container can produce 15 to 20 pounds of potatoes. Potatoes need full sun, loose soil, adequate fertilizing and steady moisture.
