Learn how to identify knotweed and what to do next
With summer just around the corner, it’s a busy time for us here at TP Knotweed. Throughout the country, new Japanese knotweed buds are sprouting, producing the first stems of the season.
If you suspect you have knotweed growth on your premises, it’s important to act fast. As experts in Japanese knotweed identification and eradication, we know the signs to look out for, but it might not be obvious to you at first glance.
To help, we are providing you with our three top tips for identifying Japanese knotweed shoots – and what to do about it.
1. Red buds
Look out for small red buds, which will sprout from the crown of the plant.
The buds are bright and cherry-like, making them easy to spot. At this point, it can be tempting to try and remove the knotweed yourself. This should be avoided. While above ground growth is small, it is important to remember that a large network of roots already exists beneath the ground.
This is the best time to treat and remove your knotweed. The removal process will be shorter than if the knotweed shoots are left to sprout, and the overall cost to you will be lower.
2. Purple shoots
In early spring, knotweed takes the form of reddish-purple shoots sprouting from the ground.
Left untreated, these will rapidly grow into the distinctive knotweed canes, but at this early point they are easily confused with the vegetable rhubarb. This is a mistake we have seen many surveyors make when examining properties, reinforcing the need for accurate professional knotweed examination.
There is still time to act. The shoots are still small and the small size of your infestation means treatment options are flexible.
3. Tall stems
As we go into summer, knotweed will grow into hollow reddish green stems with deep green leaves. These can shoot up to three metres in height. At this stage, they are often mistaken for bamboo, as the height and colour of the shoots can be similar in appearance.
During the summer they will produce thick, leafy vegetation and sometimes small white flowers. This is peak growing season. Your knotweed is going to grow very tall, very fast. It grows as easily through brick, metal piping, and concrete as it does soil.
Identify the plant as quickly as possible so treatment can begin before the stems and roots become unmanageable.

By the end of the summer, those small shoots will reach up to 3 metres in height, with root systems up to 3 metres deep and 7 metres across. By this stage, your knotweed is much more difficult to remove.
Identify your knotweed early and act while the weed is still small for shorter, more cost-effective treatment and removal.
