can you compost twigs?
Yes — pencil-thin twigs break down in a year or two and do useful work holding the pile open in the meantime.

which bins can take it?
- hot pile yes
- cold pile yes
- worm bin no
- bokashi no
- tumbler caution
- curbside yes
- tumbler: Long twigs jam the mixing fins — snap them to a few inches or leave them out of the drum.
why?
Twigs are small enough that fungi reach the core within a season or two, yet rigid enough to resist the compaction that turns a wet pile into a sour brick. Extension guides call this bulking: a coarse twig layer on the floor of a bin creates a plenum that lets air move up through everything stacked above it.
how to prep it
- Snap twigs into 3–6 inch lengths
- Lay a 4-inch twig layer on the bin floor as an air plenum
- Screen leftovers out of finished compost and reuse them
watch out for
- Twigs pruned off a diseased shrub carry those spores into the pile with them.
often confused with
- Kindling and scrap lumber — Milled scrap may be glued or treated; only twigs straight off a living plant are automatically safe to compost.
quick answers
Do I need to sift twigs out of my compost?
Only for seed starting or potting mixes, where coarse bits get in the way. In garden beds unfinished twigs are a feature — they keep soil open and go on feeding fungi after spreading.
Are twigs a green or a brown?
A brown, and an extreme one. Woody stems hold very little nitrogen, so twigs count toward your carbon side even when freshly cut and still bending.
