Can You Eradicate Japanese Knotweed in Winter?

Protecting your home and its value, as well as getting ready for spring growing are all reasons you may want to tackle Japanese knotweed removal in winter.

Anyone whose property or surroundings has been blighted all year by Japanese knotweed may well be feeling great relief at this time of year, as winter is upon us and the destructive plant has not only stopped growing, but it appears to have died altogether. Is this the end of the problem and you can get on with your life, rather than trying to battle this highly invasive, non-native species that's causing havoc to properties all across the UK?

Unfortunately not. Although it may look like Japanese knotweed has died by the time winter comes around, it has only really become dormant, surviving on energy stored in its extensive underground rhizome network over the coldest, darkest months of the year.

If you have Japanese knotweed on or near your property, it will most likely look like leafless and brittle bamboo canes that have turned brown and have no life in them. Underground, however, it's a different story entirely, as the large rhizome root system of Japanese knotweed is very much alive and waiting out the winter before sending up more shoots to cause all sorts of destruction. So can you carry out Japanese knotweed removal in winter, or is it best left until spring or summer arrive when the plant’s growing?

Wintertime in the Garden

Let's face it: there's nothing much going on in the garden during the long and dreary winter months. There may be some basic maintenance and cleaning up of debris, but that's about it. There's no lawn to mow, as the grass is not growing; no flowering plants to tend to or shrubs to prune — but if you have Japanese knotweed lurking somewhere in the garden or another part of your property, getting it out of there now, and for good, will ensure the garden is perfectly positioned for hours of enjoyment over the coming spring.

The job of Japanese knotweed removal in winter is actually made easier because there's no above ground vegetation that you have to contend with — just the brittle stems that can easily be cut down and taken away. Then it's on to the main task of dealing with the powerhouse of this difficult weed: the root system itself.

It's not possible to use herbicides during the winter months to kill off Japanese knotweed, as the plant must be in leaf. The solution you're after at this time of year is a dig-out of the affected area. Here at Environet, we have developed a patented, environmentally friendly method of doing just that. It's called Resi-Dig-Out™, and it ensures no part of the root system is left in the ground, and that the soil is returned to the same location so there's minimal disruption to the area.

Japanese Knotweed Removal: Gone for Good

We know that many people think their Japanese knotweed problems have disappeared during the winter, and they hope it will stay that way. That's why we usually see a drop in enquiries towards the end of the year — but then a flurry of calls and emails in the spring when the weed has sprung back to life and is growing out of control all over again.

Wouldn't it be great if you managed to get rid of your Japanese knotweed headache during the winter, so you’d be all set for the coming year? You'd also be protecting your valuable property from any damage caused by the roots, or a loss in value. In a recent survey we commissioned, we discovered that around £20 billion has been wiped off the value of UK houses due to Japanese knotweed. If you're thinking of selling a property that has Japanese knotweed on it, now — during winter — is the ideal time to knock it on the head for good.

And with an insurance-backed guarantee for up to ten years, you can finally say goodbye to all your Japanese knotweed worries.
