This spring appears to have been particularly good for Knotweed. I seem to see it everywhere. The battle in my garden has been temporarily won with no Knotweed coming up this year, but the plants are still just over the fence and need more killing.

But the sad thing was going for a walk in Sydenham Woods this weekend and Knotweed can be seen taking hold in a number of patches through the woods. I'm sure this must be a real danger to the survival of this woodland.
