What's the best way to get rid of Japanese Knotweed?

Question

I'd prefer not to use weedkiller, unless it's absolutely necessary

Answer 1

You will need weed killer - that stuff is a bugger to kill off - cut it back to one inch above ground level and pour weedkiller into the shoots.

Check it out here - it is evil stuff that can root itself and burrow into concrete

Answer 2

THe dreaded Japanese knotweed dont know how much you have but as you are probally aware it is a hollow growth cut the top to allow you to poor a solution of bleach and water and jeyes fluid down the stem this will enter the root system immediately and it will keel over shortly then dig it up and burn it. good luck dont plant the ground for a month

Answer 3

You know how to pick them dont you??!!!This plant is an absolute beast,my professional dealings with this have been interesting to say the least.There is only a handful of effective chemicals to handle this plant & most if not all are only available to trained ppl.They are not 100%.The best way to deal with this is to starve it of light, ie keep cutting it.Dont give it an inch,cut at ground level as soon as it sticks up shoots.It may take 4-5 years+ to get rid of!!All plants need light to survive & this is the only method that seems to work on this one.Hope this is helpful

Answer 4

It has to be dug out with the roots, and even then you need to put weedkiller down where the roots were. Only one bit of root left in the ground is enough for it to grow back.
