Japanese Knotweed in spring, spot the warning signs

Although Japanese Knotweed will decompose and become dormant in winter, the first signs of its rebirth are noticed in Spring where it is at its weakest. In the majority of cases, Japanese Knotweed growth is first noticed in March. Watch out for pink and red buds rising up from the ground as these buds are evidence of a highly expensive Japanese Knotweed problem in the future.

The plant’s early stages in spring have been likened to asparagus spears and these spears will grow at an alarming rate into hollow and thick canes. These spears have been likened to bamboo, featuring a unique pattern of purple speckles. Over the forthcoming weeks, green leaves will start to unroll from these canes as the plant’s growth continues.. You will then start to notice pointy heart shaped leaves with a zig zag pattern evident on its stems.

Why Knotweed in 2019 is more problematic than 2018

In the spring of 2018, the infamous “Beast of the East” caused destruction all over the U.K but the snowstorms acted as a thorn in Knotweed’s side as it postponed the emergence of the plant to late April and early May.

The aggressive growing plant does not face that problem this year and cases of Knotweed have already been reported, making it two months early compared to 2018. In certain parts of Britain, average temperatures have hit 10 degrees and this warmer weather has aided Japanese Knotweed in its early emergence. Property owners should be alarmed by this fact as its early growth can seriously affect a property’s value, unless a professional treatment plan is put in place.

Not all hope is lost and Japanese Knotweed experts, like the experienced and qualified surveyors at Wise Knotweed Solutions can educate you on how to identify Japanese Knotweed at this time of the year while the plant is vulnerable. Take note of the signs now before the invasive weed is able to affect the value of your property.

Why Japanese Knotweed is an immediate cause for concern 

You may be surprised to learn that Japanese Knotweed is quite attractive looking plant. However, don’t let its appearance fool you. If left untreated, it can seriously impact a building’s structural integrity.

It can grow at an alarming rate of over 3 feet a week and if left untreated, it will reach at least 3 metres in height. While its leaves and canes continue to increase in size, the roots of the plant can grow up to seven metres in any direction. This is how it can affect the structural integrity of a building as it is capable of getting through even the most narrow holes in masonry and concrete.

This can be a concern for property owners looking to sell and potential buyers, as a number of banks and building societies are refusing to provide mortgages on properties affected by the plant if there is no professional treatment programme in effect.

What should I do if I think I have Japanese Knotweed?

Long term property damage is certainly avoidable if the vicious plant is treated in time.

If you notice any unusual looking plants growing on your property then it is crucial that the plant is examined and a treatment programme put into place by an expert surveyor. The easiest and most affordable time to deal with a Knotweed issue is spring so act fast before the plant grows out of control.
