GROWING POTATOES IN A SMALL SPACE

If a lack of garden space has prevented you from trying to grow 
potatoes in the past, here's a technique that might work for you. 
Start by creating a round cage out of metal chicken wire, about two 
feet in diameter. Then, place six inches of soil and compost inside 
it. Put two or three seed potatoes on top of the soil and cover them 
with another four inches of soil/compost mix. Now, wrap the outside of 
the cage with burlap or an old sheet. This will keep out the sun. 
Every week for the next six weeks, add another inch of soil and 
compost, and water a couple of times a week if it doesn't rain. You 
can also pour on a little "compost tea" every three weeks or so. At 
the end of the season, when the foliage has all shriveled, you can 
dump the contents out from the cage and harvest all the potatoes that 
tumble out.
