Japanese knotweed
Dead canes are in the compost bin and the beds look clear. Why should those canes not be carried off the site as ordinary garden waste?
Not ordinary garden waste. Dead canes in the compost bin should not be carried off the site as normal green waste, even if the beds look clear. Japanese knotweed must not be caused to spread, and it must not be put out with ordinary garden waste or composted as if it were hedge trimmings. Dead material can still be knotweed. Clear beds do not reclassify the canes. Leave them, and get advice on lawful disposal. Do not load them into a boot, a tip run, or a council green bin as a tidy-up.

What is the fuller explanation?
GOV.UK is plain about not spreading Japanese knotweed and not disposing of it as ordinary waste. A compost bin is not a treatment works. Canes that look brown and finished are still plant material from the stand. Moving them to a tip, a friend's garden, or a green-waste collection can spread the plant. The fact the beds looked clear on the visit does not change what is already in the bin. Looking clear and being safe to carry away are different statements.
The survey can record canes in the compost and beds that showed no fresh growth that day. It cannot authorise you to remove the canes as household gardening. Do not ask the surveyor to label them harmless because they snapped easily. If knotweed is suspected, stop moving soil and cuttings. Ask a person who deals with knotweed how this material should be handled, and keep it on site until that is clear.
What should you ask your surveyor?
- Did you identify the canes in the bin as knotweed, or only as dead stems?
- Were the beds clear of growth, or only recently cut back?
- What should not be removed from site while those canes stay unassessed?
What are the typical next steps?
- Leave the canes on site rather than taking them as green waste.
- Do not compost them or put them in an ordinary garden-waste collection.
- Get proper advice on disposal before any of that material is moved.

Also asked about this
If the canes are dead, can they go in the green bin?
No. Dead knotweed canes are not ordinary garden waste. Do not carry them off site that way, even when the beds look clear.
Do clear beds mean the compost bin is harmless?
No. Clear beds do not reclassify canes already in the bin. Keep that material separate from normal waste until disposal has been properly arranged.
