Hi, I'm planning to grow potatoes in a 19 Gallon Blue Plastic Tub with Rope Handles. I'll drill holes in the bottom for drainage and I'm planning to fill with a lot of compost and vermiculite and spagnum peat moss(nice acid). I'll fill the bottom about 4-5 inches deep and then place 3 red pontiac tubers on it and cover with several inches more. As the plants grows, I'll cover the stems to just under the leafs as they grow...until I get to the top of the container. I'll add slow release 7-7-7 fertilizer as the plants grow.
I'm planning on February to put inside my shed (south roof is long and glazed) for the days and nights below freezing and on good days I'll put them outside.
Does this plan sound right? Does the potting mix sound ok? The fertilizer? The timing of the year?
thank you for any advice,
