About 4 weeks ago, I took some fresh summer growth clippings from one of my trees and burried them in coarse sand/fine gravel next to and mixed with compost from my compost pile. I pulled some of the ends out a couple of inches, then mulched with a little straw, and have watered every other day or so to keep them damp. The clippings are planted next to a block wall and are fully shaded till around noon. From noon on they are under 50% shade cloth.
I am greatly amazed that they didn't just become compost. I would never have even tried this if I hadn't read about it here first.
