New to all this, but have been making lasagne beds using horsemuck straw & my nearly ready compost. Want to try hugelkultur got me wood ready but no soil only my compost & straw & horse, sheep hen muck. Soil here is very stony mountain land. We also get a lot of rain & strong winds. Could you use shrub prunings i've got a load of butterfly bush I could get rid of? Any help gratefully received!
