It's an odd sounding question in a week of odd forum questions, but has anyone used or heard of mulching with whole (small) logs? I use am using logs under new hedges, as a mix of habitat for beetles etc and as a mulch to keep precious water in so new trees do not to dry out. I want to put log piles under all my hedging - not touching the bark (so as to not encourage plant rot) and not close packed (so that water easily runs off to the plants). I've seen bark and woodchip used, but never larger pieces.
The plan does seem to make sense to me; Even on raised beds, with plants put into between the logs (?); as I have a large, free supply of wood, from my own trees and a local tree surgeon.
The advantage for hedging would be that not many ground-cover mulch plants (like clover) would be happy in the darkness under there. Bark and woodchip is great for extending wildlife habitat (I have found) but logs might be even better.
Your thoughts are very welcome. Many thanks.
