Can you compost citrus peel?

Citrus peel composts perfectly well in a normal heap; it is simply slow, because the oils and the waxy rind resist breakdown. The old advice that citrus acidity harms compost does not hold up — the acidity is neutralised quickly as decomposition proceeds. Worm bins are the real exception: the d-limonene in citrus oil is genuinely irritating to worms, and large amounts will drive them away from that part of the bin. Chop peel small and keep it to a modest fraction of what goes in.

How to do it properly

1. Chop peel into small pieces so it breaks down at the same rate as everything else.
2. Keep it a modest share of total volume rather than a whole bin of it.
3. Balance with plenty of brown material — cardboard, dry leaves, shredded paper.

What goes wrong

• Whole peels can sit intact for a year or more.
• Worm bins react badly to citrus in quantity.
