I have always wanted to make some kind of potato tower. Last fall, I made a quick compost pile (while the snow was flying), but because I made it so late, it did not have a chance to decompose very much. So during our class, we turned the pile onto the lawn, mixed it with some wood and water, and piled it into a wire cage. (During the winter, I use these cages to protect my trees and shrubs from rabbits).
Then we planted potatoes in it, leaving some space to add some straw and leaves as the potatoes grow. After 2 weeks, the potatoes are just starting to poke out.
We also had some partially composted material for a second “vertical growing cage”. I added a layer of soil and seeded some buckwheat for a cover crop. In a week or so, I will be planting a muskmelon in it, just to see if it will grow and mature. I love experimenting in the garden, don’t you?!
