Large Infestations of Japanese Knotweed

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.)

How to identify Japanese knotweed

If you’re concerned a fast growing plant in your garden may be Japanese knotweed, here’s what to look out for:

Bamboo like stems, which are green with purple speckles

Zig-zag stems with flat leaves, heart shaped at the very tip

Roots that snap like a carrot, with an orange circle to them

Do like to see the hard work last year paid off!

Stem injection of Japanese Knotweed can be very effective way of controlling the beast.

I carried out one visit of stem injection and sprayed the small stems over a few months last year.

This year as the infestation is not too old… there are no signs of any regrowth!
