by finn on Apr 22, 2020
Japanese knotweed can be the bane of a great many homeowners, the invasive "ornamental" plant is quite possibly the most hated plant due to its rhizomes. It grows around 7 feet high and the roots, which are the real problem, can go twice as deep. The plant grows back every year and if you miss even a tiny bit, then well, it comes back, which is probably why your reading this. It can even make it difficult to sell your house, and certainly won't help you sell your home fast, sometimes it can be worth getting in some professionals to handle the job
Step 1 – Cutting
Knotweed doesn’t regrow from the stalks, so trim it down to start with, this will make getting it out of the ground much simpler.
Step 2 – Weedkiller
Best to use a Glyphosate weedkiller, brands like roundup tend to be this type. Apply it to all the stems, it will kill almost all vegetation it touches. Do this immediately after cutting down the stems.
Step 3 – Leave it
This is where most people go wrong, you need to wait for at least 7 days. This gives the poison time to get down to the roots. Now you can pull out and remove the dead roots.
Step 4 – Keep killing it
If you keep killing any remaining upshoots weekly this will prevent remaining roots from regrowing strong.
Step 5 – Reapply Glyphosate
Unfortunately, a one time spray isn’t going to cut it. You’re going to need to do this more than a couple of times. We recommend at least every 3 months.
Step 6 -Bring in the professionals
If this doesn’t work, you may need help, you won't be the first or the last and it is sometimes just all that can be done.
Step 7 – Disposal
Due to its invasive nature, you have to take knotweed to a registered landfill site is common in a lot of countries.
Step 8 – Transport it to a landfill
