Beautiful crown not active today! So called because of all the rings (broken off dead stems) which apparently look like a crown. Don’t think I’d like to wear it though!
… are mushrooms. I came across these lovely specimens in woodland where Japanese knotweed was growing. However I’m not in a hurry to eat them! I’ll stick to steamed Japanese knotweed or Japanese knotweed jam!!
Lovely growing bonsai Japanese knotweed seen in Sydenham. A little chemical treatment was given to control the plant.
Perfect conditions here, no Japanese knotweed present on this visit. The trees are providing a good canopy for reduced light penetration and ivy is now covering the ground.
I love visits like this! Dead canes of Japanese knotweed.
No one has touched the area since last year and the plant is happily not active – great control!
… or not? An interesting listen from BBC You and Yours programme questioning the 7 metre rule: https://www.bbc.co.uk/programmes/b0bd6ycp
Treating large infestations of Japanese knotweed does take time. Using stem injections six months later can have some good initial effect, but still requires long term monitoring. (Yes for those keen eyes there is more Japanese knotweed in the background of the second photo! At this visit requested not to treat it, which is why monitoring is also so important to control the activity of the plant.)
PCA’s Technical Manager for Invasive Weeds Peter Fitzsimons, spoke on the BBC Radio Ulster – On Your Behalf programme about Japanese Knotweed.

There has been much in the press about Japanese knotweed this week; here is a link to what we think is a more balanced approach from the PCA: https://www.property-care.org/trade-association-sets-the-platform-for-debate-around-new-japanese-knotweed-findings/
