Judy, I hope you heal quickly, and you have flowers to enjoy while you are recovering. At least it wasn't an ankle! If you were here, I'd make a comfrey poultice for you. If you know someone who's got comfrey, mash up some fresh clean roots in a blender and wear it overnight wrapped with a cotton washcloth or similar. Jim, The wall project sounds terrific! I think they offer more than one size of cinder block, say at a landscape supply yard. Perhaps a concrete stain would help until the plants were established? I'd avoid home depot, their blocks are inferior quality and cheaply made. Travis Owen Rogue River, OR amateuranthecologist.blogspot.com
