Making Leaf Mold from Your November Leaf Fall

As autumn winds down, piles of fallen leaves cover lawns, beds, and borders. Don’t bag them for the bin! Turn November’s leafy bounty into leaf mold—a crumbly, dark, soil conditioner that rivals compost for improving garden beds, pots, and seed sowings. Here’s how to easily make leaf mold from your November leaf fall.

Why Make Leaf Mold?

• Supreme soil improver: Adds structure, boosts moisture retention, and supports soil life.
• Free and easy: Just store leaves and wait—no turning or careful balancing required.
• Peat-free: Leaf mold is a sustainable alternative to commercial peat.
• Perfect for seed sowing and mulching: Gentle and weed-free.

What Leaves Work Best?

• Deciduous trees: Oak, beech, hornbeam, maple, ash, sycamore—break down beautifully.
• Avoid: Evergreen leaves (very slow to rot), thick magnolia/laurel (shred first), or walnut/eucalyptus (may release compounds that suppress plants—compost separately).

Simple Steps to Make Leaf Mold

1. Gather Leaves

• Rake up dry, clean leaves from lawns, borders, and paths.
• Avoid twigs, rubbish, or leaves with obvious disease.

2. Pile or Bag

• Wire cage / open heap: Make a mesh pen or heap leaves in an out-of-the-way corner.
  • Dampen as you build the heap—moisture speeds up breakdown.
  • Pile at least 1m x 1m for best results.
• Black bag method: Fill large bin bags or old compost sacks, moisten lightly, tie, and poke holes so air gets in.

3. Leave and Wait

• Place bags or heaps in a shady, sheltered spot.
• Check every few months; add water if too dry.
• After 6–12 months: Leaves break down to a coarse, dark mulch.
• After 1–2 years: Fully rotted, crumbly, earthy-scented leaf mold—perfect for mixing into compost, mulch, or sowing.

Using Leaf Mold

• Mulch beds and borders to suppress weeds and conserve water.
• Sieve fine leaf mold for seeds and potting mixes.
• Improve clay soil—incorporate 5–10cm yearly for better drainage and root growth.

Tips for Leaf Mold Success

• Shred or mow leaves for faster breakdown.
• Mix different kinds of leaves for a richer product.
• Don’t let heaps dry out completely.
• Add collected leaves all winter as more fall.

Making leaf mold is simple and slow but incredibly rewarding—November leaves become next year’s planting gold.
