can you compost raspberry canes?
Yes, but cut them short and sort out the diseased ones — thorny canes stay sharp and intact for two years whole.

which bins can take it?
- hot pile yes
- cold pile caution
- worm bin no
- bokashi no
- tumbler no
- curbside yes
- cold pile: A cool heap leaves thorny canes sharp for a season or more — an unpleasant surprise at turning time.
why?
Spent floricanes are woody with a hollow pith, and the thorns are lignified outgrowths that survive long after the cane itself softens. Cane blight, spur blight, and anthracnose all overwinter inside cane tissue as fungal structures that release spores the following spring, which is why extension programs tell growers to prune out and remove infected canes rather than heap them at the end of the row. Healthy canes chopped short are ordinary browns.
how to prep it
- Cut canes into 6-inch lengths with loppers
- Wear leather gloves — the thorns outlast the cane
- Bag canes with sunken purple lesions or split, peeling bark
watch out for
- Cane blight and spur blight overwinter in the wood and a cool pile keeps the spores viable; infected canes should leave the property.
- Cane tips that touch soil root on contact, so a tip-layered cane tossed on the heap can start a whole new plant.
often confused with
- Rose Prunings — Both are thorny woody canes with the same chopping rule; roses add black spot to the disease-sorting list.
quick answers
Can raspberry canes be used as mulch or plant supports?
Dried canes are too brittle for stakes but chip into a decent coarse mulch. Bundled cut canes also make good bee hotels, since the hollow pith is nesting habitat for native mason and leafcutter bees.
Which raspberry canes am I supposed to cut out?
Floricanes, the ones that fruited this year, die back on their own and should come out at ground level after harvest. The green primocanes stay for next year. On everbearing types it depends on whether you want one crop or two.
