Want a fun, low on space way to grow potatoes? Grow them in a garbage can!
With either a new a garbage can (or a used one that is super-clean), drill several 1/2 drainage holes in the bottom and on the sides close to the bottom. In the bottom of your garbage can, place a layer of shredded newspaper or old junk mail. This helps to keep the soil that you add on top of this moist and also helps to keep the soil from finding its way out of the drain holes to make a mess. You then fill the can with about 6 inches of good potting soil, and if you like, some fertilizer. I personally would use the “square foot gardening” mix of 1/3 peat moss, 1/3 compost and 1/3 asbestos-free vermiculite.
