Can I make a plea that when you're raking up those autumn leaves, you leave a pile in a quiet corner, rather than bag or bin all of them. In our first autumn at this garden we rigorously raked and bagged the leaves from our big ash trees as they fell, in an effort to keep them off the lawn which in previous years had been allowed to suffocate under the thick blanket of leaves.
Just as the winter was turning really cold we came upon a hedgehog who had scraped together the few leaves he could find to make his hibernation home in a garden which in other winters had always provided him with a thick cosy blanket of leaves.
Fortunately we were able to move the hedgehog to a sheltered corner and protect him with a thick insulating layer of hay from the pet shop, and he came through his hibernation safely.
In the following winters we've raked the leaves off the lawn and bagged some of them, but left plenty in piles in places where the hedgehogs can gather enough for their nests, and only when the hedgehogs have stopped visiting the garden every evening do we bag the remaining leaves up to rot down for leafmould.
Remember the hedgehogs!
