How to Compost Citrus Peels & Onion Skins Safely

Citrus peels and onion skins are great for composting, but they require special handling to break down efficiently without causing problems. Whether you're using a traditional compost pile or vermicomposting (worm bin), here’s how to compost them the right way!

1️⃣ Why Citrus Peels & Onion Skins Need Extra Care

🚨 Challenges with Composting Citrus & Onion Skins:
✔ Slow to Decompose – Citrus peels have natural antimicrobial oils that prevent bacteria from breaking them down quickly.
✔ High Acidity – Citrus peels can lower pH levels, which may slow down microbial activity in your compost.
✔ Strong Odors – Onion skins and citrus can create strong smells, attracting pests if not composted correctly.

🔹 For worm composting (vermicomposting) – Citrus peels & onions can be too acidic and strong-smelling for worms.

2️⃣ Best Ways to Compost Citrus Peels & Onion Skins

🌿 Traditional Composting (Hot or Cold Pile)

✅ Chop into Small Pieces – Smaller pieces decompose faster than whole peels.
✅ Mix with Brown Materials – Balance citrus peels & onion skins with carbon-rich materials like dried leaves, shredded paper, or cardboard.
✅ Turn the Pile Regularly – Aeration helps break down citrus oils and prevents strong smells from onions.
✅ Use a Hot Composting Method – A compost pile reaching 135°F–160°F (57°C–71°C) will break down citrus & onions more quickly.

🐛 Vermicomposting (Worm Bin)

❌ Avoid adding too much citrus or onions to a worm bin, as they can be harmful to worms. If you must add them:
✔ Use in Tiny Amounts – A small sprinkle of dried, crushed peels won’t harm worms.
✔ Neutralize Acidity – Mix citrus peels with eggshell powder to reduce acidity.
✔ Precompost First – Let citrus and onions decompose in a separate pile before adding them to the worm bin.
