Jealousy, I has it.
I am discovering that even very minor additions to my available resources can make a huge difference in my
permaculture projects. Last year, it was getting a wheelbarrow, and later stumbling over a huge trove of empty plastic nursery pots and containers. This year, it's been the huge pile of
wood chips from the tree trimming guys, which have provided me with a technology for mulching out weeds around my plantings where before I simply didn't have
enough mulch to do the job anywhere.
An excavator, even a tiny one, is going to revolutionize your projects. Have fun with it!
