Getting enough mulch is an ongoing problem here too.
Last year we produced several large piles of woodchippings from tree clearance, also collected a lot of leaves from the quarter mile lane to our house. But that has all been used up now.
What grows profusely everywhere here is stinging nettle. I have wondered about topping that to use as mulch - as long as I don't pick up any root fragments. Would nettle be okay as a mulch?
