Japanese knotweed
Cut canes that look like knotweed are in a skip and no live stand was in the beds. What has the skip not proved about the ground?
The skip has not proved that knotweed is in the ground, and it has not proved the ground is clear. Cut canes that look like knotweed are in a skip, and no live stand was in the beds. A skip can hold debris brought from anywhere, and cut stems are not a growing plant mapped in the garden. The survey has recorded the canes and the absence of a live stand. It has not tested the soil and has not identified a stand in the beds.

What is the fuller explanation?
Japanese knotweed is identified from growth in the ground, not from a pile of cut stems in a skip that might have come with other rubbish. Canes that look like it are a reason for caution. They are not a live infestation the survey has plotted, and they are not a clearance certificate. No stand was seen in the beds on this visit. The soil was not sampled.
Tell the solicitor about the canes in the skip and that no live stand was seen in the beds. If you need the ground checked, ask a specialist who deals with knotweed, and do not treat the skip as their report. Do not tell a lender the garden is clear because the beds looked empty. Keep any management plan, if one appears, separate from a pile of cut canes.
What should you ask your surveyor?
- Where is the skip, and what do the cut canes look like?
- Was any live stand seen in the beds?
- Was the soil tested, or only the skip and the beds looked at?
What are the typical next steps?
- Tell the solicitor about the canes in the skip and the absence of a live stand.
- If the ground must be checked, ask a knotweed specialist rather than rely on the skip.
- Do not tell a lender the garden is clear because the beds looked empty.

Also asked about this
If the beds look tidy, has the ground been proved clear of knotweed?
No. Tidy beds mean no live stand was obvious there, which matches the note. They do not prove the soil is free of knotweed, and the skip has not proved that either. The survey did not test the ground. Emptiness of the beds is not a clearance.
Can the cut canes in the skip be treated as a live stand mapped in the garden?
No. Cut canes in a skip are not a live stand the survey mapped in the garden. No live stand was in the beds. The skip has not proved knotweed is established in the ground, and it has not proved the opposite. A heap of stems is not a plotted infestation.
