Grow potatoes in a trash bag?!

So a friend was telling me of growing potatoes in a bag of potting soil. I was so perplexed by this that I just had to research it more.

I'm all out of room in my veggie beds but really want some Irish potatoes. So I'm thinking I'm going to try this.

I have another friend that has no means of making a large garden and wants to do container gardening. I decided to include links on growing root vegetables in (that's right) TRASH BAGS!!!!!

Check it out!!!!!

And here for carrots!!!!

While the second site recommends a "growbag" I don't see why you couldn't do the same thing as the potato trash bag. Maybe use contractor bags like these for a more heavy duty, puncture-resistant material.

When I get mine started I'll post updates! Let me know if you decide to follow suit!!
