which bins can take it?
- hot pile yes
- cold pile yes
- worm bin yes
- bokashi yes
- tumbler yes
- curbside yes
why?
An apple is about 85% water, so once the skin is breached, bacteria and fungi liquefy the flesh in days; the woody stem and seeds are the only parts that linger. The seeds carry trace amygdalin, but at compost scale that's chemically irrelevant. An exposed core's real talent is summoning fruit flies and yellowjackets, which burying solves.
how to prep it
- Bury cores in the pile center, not on top
- Chop halves if you want them gone in weeks
quick answers
Will apple seeds sprout in my compost?
Occasionally, especially in cool piles that overwinter. Seedlings pull out with two fingers, and an apple grown from seed wouldn't match the parent fruit anyway.
Can I compost bruised or mealy whole apples?
Absolutely — drop-fruit is a fall staple of orchard composting. Quarter whole apples so they don't turn into sealed balls of cider inside the pile.
