Citrus fertilizer for the compost bin
Lemon peels have become fertilizer in the kitchens and backyards of generations of gardeners, who realized nothing citrus goes unused. It works because the peel is rich in carbon, potassium and aromatic oils — but those oils break down slowly, so the secret is chopping finely and dosing carefully, so the compost's microorganisms can work undisturbed.
What you need
- Lemon peels (and other citrus peels, if you like)
- A knife or scissors for chopping
- Your compost bin or a compost bucket in progress
- Dry balancing material: dry leaves, shredded cardboard or sawdust
How to make it
-
1
Chop the peels into very small pieces — the smaller the piece, the more surface area for the microorganisms to attack, and the faster decomposition happens.
-
2
Add the peels in small amounts, spread through the middle of the compost, not in a pile of peels alone — a single layer avoids a buildup of citrus oil, which keeps worms away when too concentrated.
-
3
Cover each portion with dry material, like leaves or shredded cardboard — this balances the peels' moisture and prevents strong smells.
-
4
Turn the compost once a week to aerate — oxygen feeds the decomposers and keeps the mix from rotting instead of becoming fertilizer.
-
5
In a few weeks the peels break down and blend into the dark, earthy compost, ready to enrich pots and vegetable beds.
Finishing touches
If your compost has worms, start with little citrus peel and observe: if the worms move away, wait longer between portions. The finished compost is excellent for tomatoes, peppers and other plants that love potassium.
