Mulching is a natural way to build up soil and add nutrients, but if you let your leaves stay where they fall, they can create a natural habitat for pests and some diseases.
If you put your leaves in a compost pile, you may notice that many are still intact while the vegetable matter breaks down. This is because many leaves that fall during autumn contain a protein that rots by fungi instead of bacteria, causing leaves to take longer to break down.
The best way to make leaf mold is to separate it. Place all the leaves in a large black plastic bag, tie the bag closed, puncture it all over and store it for about a year.
And that’s how easy it is to make a free soil amendment — just make sure you give the pile enough time to break down!
