Is it possible to have too much mulch? That's an alien idea for me, I've never had enough to even do all my beds. Well, the tree trimmers have been busy around here, and have dropped loads of free mulch off to everyone in the area who wanted some, and nobody around wants anymore. So I told them I can take as much as they can bring. We showed them where to put it, and what I can see from the house hasn't changed much in the last couple of weeks. I went out yesterday and walked around the pile to see they've been bringing LOTS! OMG, I have a mountain range of mulch out there!
