Digging potatoes up from the ground can be a difficult process, especially when the native ground we have in our area consists of a mix of clay and granite. Not only is container gardening with a mix of potting soil and organic waste a lot easier to work with when it comes to harvesting potatoes, it also provides them with more room to grow because the potato roots do not have to fight against the compact soil of native Colorado Rocky Mountain soil.
This video examines the simplicity of using Trash Cans to Grow potatoes. To build a Potato garden of your own, all you need to do is drill a few drainage holes in the bottom of the 20-gallon trash cans that you purchased either online or at your local retailer. Fill each trash can up half-way with potting soil and place a 3-inch layer of horse manure or organic compost fertilizer on top. Mix and let your garden sit over the winter to allow the compost or manure to work itself into the soil over the winter months. (Note: If you're starting these in the springtime, the Organic Compost Fertilizer sold by Amazon is already composed and will allow for planting immediately.)
In early spring, once the potential for a hard freeze has past, insert one or two small organic potatoes per trash can into your soil. Then, all you'll need to do is water your potatoes once or twice a week until harvest.
