Raised beds around trees?
What are you thoughts about making raised beds around large established trees? My property is woods, and the ground is all rock. You can't dig at all with a shovel, and to make any kind of hole you need to use a pick, so really the only way to have a garden is to raise it up. I would like to make more gardens around some trees, but am now wondering if I will be harming the trees in any way. The last garden I made around a large tree, I surrounded the trunk with rocks to keep most of the dirt away from the trunk. What do you think?
