GROWING POTATOES IN A TRASH BARREL
Jennifer needs some assistance, "I live in the Pac NW and I am attempting to grow potatoes in a trash can. Has anyone tried this already? What worked best for you? I'm worried that with all the rain it might be too wet for this. Any advice would be great!"Thu at 1:57pm · Comment ·UnlikeLike · View Feedback (15)Hide Feedback (15)You and 2 others like this.
Karen Littrell Long as you have plenty of drainage in the bottom of the can, you should be ok. Put about 6" of organic soil in the bottom and set your seed potato on it. Add just enough soil to cover and water well. When you see it sprouting, keep adding soil, layer by layer as it grows till maybe a few inches below the top. All along that stem you will have some...

Thu at 2:13pm · ReportMary Simpson Dailey Have done this for years, lots of trial and error. Do make sure you have plenty of drainage holes in bottom and a row or so on sides of can (down low). I do the add dirt/peat moss mix, as soon as I see some growth. But when you see green, stop adding more layers. Watch over fertilizing or you will wind up with lots of great foliage and few ... See Morepotatos. Also while it needs sun, full sun heats up a dark can quickly. I finally have a spot where it gets morning till a little afternoon sun and shade then on. It has been the most successful spot so far. Good luck, its fun. Makes harvest easy.

Thu at 3:58pm · ReportTheresa Tyree LOTS of drainage holes so they wont get wet. I've done it in stacked tires also but the water in the tires can get stagnant.
Thu at 4:43pm · ReportJohnson Utility I grew potatoes in old stacked tires. It worked great!

Thu at 8:28pm · ReportMichael Williams I've read that only late season potatoes work this way, early varieties only grow about 6" deep, assuming you are trying to mound up your potatoes. Another way to do this is 4 2x2 posts and attach 1x6 boards on the sides, as the plant grows taller you attach more boards and fill in with dirt. At the end of the season you simple unscrew one side and watch the potatoes fall. This way works a bit better in that your plant will get better sunlight.
