There might be a new chill in the air, but autumn is a beautiful time of year, when the leaves change color on the trees and the sun shines through a million little stained-glass windows.

If they fall into ponds they can foul the water, on the lawn they can cause bleached patches and they make paths slippery in the winter. Gardeners everywhere spend the autumn raking up leaves to prevent these problems, but did you know that you can turn them into free soil improver for your garden, rather then sending them off with the rubbish?
