My 2008-2009 Winter garden
My 2008-2009 Winter garden such as it is. I have to get in there and do some thinning tomorrow also plant the second crop. The one thing that I noticed is that even for plants this small, the roots have grown vertically for about 4" and 4" across the bottom. That tells me 6" is not nearly deep enough for a raised bed. Unless it is on top of good garden soil.
