While growing potatoes in containers may not be the most efficient method of cultivation, it is possible and you can obtain a reasonable crop. So if you want to grow some spuds but are short of space or are just looking for a fun idea for all the family then read on to learn how to do it. The instructions are contained in an article by Ciscoe Morris which I found on the Seattle Times website.
IT REALLY IS possible to grow potatoes in a garbage can. It?s more for amusement than production, but sometimes you end up with a pretty good harvest.
One thing?s for sure: Kids love growing spuds in a garbage can, and it?s a great way to get them excited about gardening. Nurseries sell special potato-growing containers, but any clean 15-gallon or bigger plastic garbage can will do. Don?t use galvanized steel cans, because they rust out.
Begin by drilling several half-inch-wide drainage holes in the bottom and up the sides, about 2 inches up from the bottom. Good drainage is essential. If the roots sit in constantly wet soil, the plants will rot.
Buy starter potatoes online or at your local nursery, and plant them whole, 5 inches apart, just under the soil surface. Plant only one variety of potato in each can.
Water the potatoes when you plant them, and before long, growth will occur. As soon as the vines grow to 4 inches tall, cover all but the top inch of the lowest-growing vine with compost, wood chips or potting soil.
