You have heard terrible stories about Japanese knotweed and how it is capable of devouring a property rendering it worthless. This is because Japanese knotweeds are invasive plants, which grows rapidly. If left untreated, it can damage any property. For this reason, you need to act immediately.
If you do not want this plant in your property, you need to thwart it but before learning the methods, it is prudent that you learn how to identify its kind. Identifying Japanese knotweed is challenging because it tends to resemble other plants. You have to pay attention to the following:
- Buds: you should watch out for small, bright and cherry-like buds. These buds usually
sprout from the crown of the knotweed. The buds are tempting to remove but you have to remember that there is already a large network of roots existing beneath the ground. This is the perfect time to treat the knotweed.
- Shoots: if you missed the buds, the next characteristic to watch out for is the reddish-purple shoot. In the early spring, the plant takes the form of reddish-purple shoots. If untreated, it will grow into canes. At this point, the plant can be easily mistaken for vegetable rhubarb that is why many surveyors tend to miss it.
- Stems: as summer approaches, it will grow into hollow reddish-green stems having deep green leaves. They can grow up to three meters in height. At this point, the plant can be easily mistaken for a bamboo since the height and the color of the shoots have a similar appearance.
- Leaves: the leaves of Japanese knotweed appear to be bright green and heart-shaped. It has also flattened base and pointed tip. Its distinct form is from the leaves growing from the stems in an alternating pattern. Mature leaves can grow up to 120 mm in length. The good news is the leaves will die come autumn or winter.
- Flowers: during the summer, the plant produces small clusters of creamy-white flowers. Every plant can have many clusters. You will notice that the clusters of flowers grow from the point where the leaf joins its stem.
- Roots: the underground roots of this plant are made up of a tree-like structure called rhizome. This is the place where the plants store their energy. Its rhizome grows thick
and woody. You have to know that it is the rhizome that causes the greatest problems. The rhizome can grow up to three meters deep and it can extend up to seven meters sideways. This is how the rhizome damages building foundations and structures.
