can you compost avocado skins?
brown · carbon fruit & vegetable scraps
Yes — avocado skins compost, just on a slower clock: the leathery peel takes months where the flesh takes days.
breaks down in 6–12 months whole; 3–4 torn small

which bins can take it?
- hot pile yes
- cold pile yes
- worm bin caution
- bokashi caution
- tumbler yes
- curbside yes
- worm bin: Worms clean the flesh side and abandon the peel — expect skins to persist in the bin for months.
- bokashi: The waxy shell barely pickles; ferment the flesh and send skins to the outdoor pile.
why?
Avocado skin is thick cutin and lignified fiber engineered to shield the fruit's fat from oxygen — exactly why decomposer fungi need months to unbuild it. Pebbly Hass skins are the tough extreme; thin-skinned varieties rot noticeably faster. Torn small, the peels double as mild browns that offset mushier greens.
how to prep it
- Tear or snip skins into stamp-sized strips
- Bury them mid-pile where moisture stays even

quick answers
Why are avocado skins still whole in my finished compost?
Cutin, the waxy polymer coating the peel, resists bacterial enzymes; fungi dismantle it slowly. Screen the skins out and return them for another cycle — second passes go faster.
