can you compost tomatoes?
Yes — tomatoes compost fast; the seeds are the only souvenir, sprouting as volunteers unless the pile runs hot.

which bins can take it?
- hot pile yes
- cold pile yes
- worm bin yes
- bokashi yes
- tumbler yes
- curbside yes
why?
A ripe tomato is roughly 94% water, so it collapses into the pile almost on contact. Its seeds are built tougher: a protective gel coat carries them through digestion and cool composting alike, which is why volunteer tomato seedlings ring so many bins each spring. Sustained heat above 131°F for a few days kills most of them.
how to prep it
- Crush whole tomatoes so they don't burst later
- Hot-compost or trash fruit from blighted plants
watch out for
- Tomatoes from plants with early or late blight belong in a hot pile or the trash, not a cold bin — the spores overwinter.
- Volunteer seedlings are near-certain from cold compost; hoe them young or transplant a few.
often confused with
- Tomato Plants — Vines and foliage carry disease risk the fruit mostly doesn't — the plants have their own stricter page.
quick answers
Do I need to remove tomato seeds before composting?
No — that's neither practical nor necessary. Either run the pile hot for a few days or treat spring volunteers as free transplants; plenty of gardeners do exactly that.
Can I compost store-bought tomatoes that went bad?
Yes, mold and all. Fuzzy gray or white growth is decomposition already underway; bury the fruit so flies don't beat the microbes to it.
