How to create drainage in a raised wooden planter?
I just purchased this product [http://www.improvementscatalog.com/product/raised-wooden-planter-boxes.do] which is a beautiful rectangular wooden planter with a PVC bag liner. I just assumed when I ordered it that it would come with drainage holes. It does not. The bottom of the box is wood and although the joints are not watertight, it has no holes and is clearly not designed for drainage. Neither does the PVC bag have any holes in it, whatsoever.
How should I create drainage? This will be placed on my wooden (ipe) deck; is the draining water going to ruin my deck? Also, I want to grow edibles in this planter - will the PVC liner be a problem, i.e., will it leach chemicals?
Thanks in advance for your help!
