- ·Fallen leaves — lots of them
- ·Optional: tarp to cover in heavy rain
Steps
- 1Choose a shady, out-of-the-way corner.
- 2Cut a 12-foot length of chicken wire to make a 4-foot diameter circle.
- 3Overlap the ends and tie them together with wire or zip ties.
- 4Drive stakes around the inside of the circle to keep it upright.
- 5Rake leaves into the bin as they fall.
- 6Water the pile if it gets bone dry.
- 7Turn the pile once or twice a year.
- 8After 1–2 years, the leaves will be dark and crumbly — ready to use.
Tools needed
- ·Wire cutters
- ·Hammer or post driver
- ·Work gloves
Common mistakes to avoid
- ·Mixing in grass clippings — that makes compost, not leaf mold
- ·Packing leaves too tight — they need airflow
- ·Letting the pile dry out completely — it stops breaking down
- ·Using only oak or magnolia leaves — mix leaf types for faster results
Maintenance tips
Turn the pile once in spring and once in fall. Keep it as moist as a wrung-out sponge. Use finished leaf mold as mulch or mix into beds.
