Hi! I'm new to gardening and discovered the no-dig method.
Digging in the heavy clay soil is like digging cement. I'm not growing veggies but am using it for planting small shrubs and mondo grass.
I used a cardboard layer followed by few inches of alfalfa hay then a layer of compost & manure, then straw, compost and manure again, and finally straw on top. I soaked each layer.
Now I'm reading about possible spontaneous combustion when hay or straw has excess moisture. Plus combined with manure and compost could it heat up and possibly combust?
The top straw layer kind of dries out pretty quick so I hose it down everyday.
It is located at the side of the house and I used lawn edging to keep everything in place. It is about 25 feet long and 6 inches high after wetting all the materials.
Am I being paranoid?
Did I misunderstand things I've read?
