Anyone ever grow potatoes in boxes of straw or mulch? For all I know this is just another gardening gimmick but experience will tell. I'm using bee hive sections that a neighbor gave me for firewood--or so she thought. Late January, I set a 14 X 18 X 9.5" high bottomless bee box over a sheet of hardware cloth. I threw in some soil, compost and mulch. I put the sets on top of that. As the potatoes grow I've added more mulch. I put another box on top of the first one. Now the potatoes are up to the top of this second box. So, now it's 19" tall. Another section would bring the thing up to 28.5" Should I stop there and let the plants grow until time to harvest? I would love to hear about your experiences trying something similar.
