can you compost broccoli?
Yes — florets go fast and chopped stalks follow; keep air in the pile to head off sulfur smells.
breaks down in Florets 2–3 weeks; chopped stalks 2–3 months
C:N ≈ 16:1
which bins can take it?
- hot pile yes
- cold pile caution
- worm bin caution
- bokashi yes
- tumbler yes
- curbside yes
- cold pile: Fine buried, but cap with browns — slow-rotting brassicas can get smelly.
- worm bin: Small amounts only; sulfur odors build quickly in an enclosed bin.
why?
Broccoli, like all brassicas, stores glucosinolates — sulfur compounds that become rotten-egg-smelling gases when the tissue decays without oxygen. Florets are tender and gone in two or three weeks, but the stalk is packed with lignified vascular fiber that can sit for months uncut. A turned, aerated pile digests both without the stink.
how to prep it
- Chop stalks into 1-inch pieces
- Cover fresh additions with browns to trap odors
quick answers
Why does my compost smell like rotten eggs after adding broccoli?
That's hydrogen sulfide forming where the tissue rots without oxygen. Turn the pile and fork in dry browns; the smell usually clears within a couple of days.
Can I compost broccoli stems and leaves?
Yes — the leaves break down as fast as florets, and stems just need chopping. Even the tough peel from thick stalks composts within a single season.
