So after doing a little research I decided to give them a try.
I bought a 20 gallon Smart Pot online. The 2 lb bag of seed potatoes came in the mail. I set them on my counter top on a plate with paper towel underneath to let them sprout for about a week.
The little sprouts are a pretty purple color. I wonder if the plants will be purple too.
I've heard around here (USDA zone 5b) that people plant anywhere between St. Patrick's day and Easter, so April 15th seemed good to me. It did just snow again this week after all. First I filled the bottom 1/3 of smart pot with a mixture of Miracle Grow garden soil (I would have preferred an organic one, but oh well. It's what Walmart had. This one seemed a bit wood chippey.) and about 1/3 compost. I folded down the sides of the container so they wouldn't flop around.
The Smart Pot website suggests one potato per 3 gallons of container, so 6-7 potatoes. I went with 6 since I don't want to make it too crowded. I arranged them like this, and then buried them 3-5 inches under the soil as suggested by Gurney's. I've read you can cut big ones in half and get two but I didn't want to deal with that.
