Not a new garden??
Adding on does not mean you are making a new hosta bed.. does it? I told my DH it was to make room for the ever expanding hosta but you just never know. They are having the mature sale a Fundy Beauties and I am "JUST LOOKING" Well maybe a few wouldn't hurt.
I so far have dug out 4 backhoe bucks of sod and now the work had only begun.
