Japanese Knotweed

Debate between Lord Gardiner of Kimble and Baroness Wilcox

Tuesday 7th November 2017 Lords Chamber

[Baroness Wilcox (Con)]

My Lords, on behalf of my noble friend Lady Sharples, and at her request, I beg leave to ask the Question standing in her name on the Order Paper.

[The Parliamentary Under-Secretary of State, Department for Environment, Food and Rural Affairs (Lord Gardiner of Kimble) (Con)]

My Lords, this aggressive plant was first found in the wild in the United Kingdom in 1886 and has unfortunately become widespread here and across Europe. We are working to ensure a more successful establishment of a psyllid insect to control it. Meanwhile, local action groups, with support from government, continue to reduce and eradicate the plant; for instance, in the Medway Valley and the New Forest, where 49 separate sites have been tackled this year.

[Baroness Wilcox]

Is my noble friend aware that when knotweed stems are trimmed they are eaten by Japanese children? Will he tell us whether landowners with knotweed on their property can still obtain a mortgage?

[Lord Gardiner of Kimble]

We are discussing an invasive species. Although I am well aware that in Japan young shoots are consumed, I would not advise it here. I do not think that is a very sensible proposal for this county. On mortgages, some new policies are now available and the RICS put out a very helpful paper in 2012, which has assisted in this matter as well.
