Some people may look at Japanese knotweed as a beautiful, ornamental plant. After all, that's one of the reasons it was brought to the country in the first place! Planting Japanese knotweed on your property is forbidden for a number of reasons. However, when you realise how damaging Japanese knotweed can be, you'll probably wish you never considered planting it anyway.

You'll remember from our blog - What Damage Can Japanese Knotweed Do? - that Japanese knotweed can make it difficult to sell your home, can cause structural damage to buildings and roads and can even disrupt cables and block drains. This plant is likely to cause you a great deal of hassle, so why you'd want to plant it is a mystery!


Tree stump

When a tree is cut down, a stump of wood is usually left behind. These unsightly stumps can be removed via a process called stump grinding, where specialist machinery is used to grind the wooden tree stump down to chippings.

But is this actually necessary? Granted, a bare tree stump can be unattractive, but are there are any reasons to remove a tree stump other than making the landscape more picturesque?


Last month, the Daily Mail reported that a homeowner in Buckinghamshire had found Bohemian knotweed (Fallopia x bohemica) growing in his garden. Stuart Marshall from Aylesbury ended up calling in an invasive weed specialist to remove this troublesome plant from his property.

japanese knotweed and glyphosate

When it comes to the treatment of Japanese knotweed, there are a number of options to consider. The two most popular choices, however, are those of excavation and herbicide application.

Now, we know excavation may sound a little scary but we can assure you that your whole garden isn't going to be ripped to pieces. Regardless, the thought of having a digger on or around your property tearing away at the ground can be somewhat offputting, therefore herbicide application is often the go-to choice for many homeowners.

One of the many discussed treatments is glyphosate, an active ingredient in many herbicides. But does glyphosate kill Japnese knotweed off completely? Let's find out...


If you read our blog "When is the Best Time to Treat Japanese Knotweed?" you'll know that the plant prepares to die back in the autumn months by moving all its nutrients down into its rhizomes. Introducing the herbicide at this critical point in the weed's lifecycle will help ensure it doesn't re-emerge again in Spring.

But what does Japanese knotweed look like in winter? Well, like most plants, when the temperature in your garden plummets, they die back for the winter. Plants with rhizome systems like Japanese knotweed will preserve their energy and survive under the soil until more favourable conditions return. 

Japanese knotweed in winter becomes dry, brittle and brown. The stalks which were once red and purple and full of leaves have turned woody and bamboo-like. The canes are hollow and will collapse around each other as they die.

If the area hasn't been treated until this point, you can't guarantee that the knotweed won't come back stronger in a few months time. That's why swift Japanese knotweed treatment is always recommended.

What should I do if I suspect I have a knotweed problem?

Whether you spot Japanese knotweed on your property is spring, summer or winter, it's vital that you get in touch with a professional removal company right away. You CANNOT rely on the winter months to take care of the knotweed problem for you. 

We can survey your garden free of charge to find out if the plant you've spotted is actually Japanese knotweed. If it is, we'll be able to offer you a quotation for thorough removal, meaning the knotweed won't have a chance to spread around your property further.
