question about safe materials in garden
There have been a couple of threads I've seen about bricks and other materials not being safe to use in constructing raised beds. I like the idea that Rob (aka organicislandfarmer) had about using bamboo, except for that it will also break down over time. I even went out and got a huge pile of bamboo to start making them. But then I came up with this idea. How about making them out of PVC pipes??? I'm attaching a pic of the bamboo type that I had planned on doing but now am thinking PVC might last longer. So is PVC a safe material for an organic bed or will it leach something undesirable into my garden????
