Reynoutria multiflora (syn. Fallopia multiflora and Polygonum multiflorum) is a species of flowering plant in the buckwheat family Polygonaceae native to central and southern China. It is known by the English common names tuber fleeceflower and Chinese (climbing) knotweed. It is known as he shou wu in China and East Asia. Another name for the species is fo-ti, which is a misnomer. The name he shou wu means 'the black-haired Mr. He'.It can be difficult to prevent the spread of this vining plant and to remove it once established. The leaves are thin and fragile but the stems, although narrow in diameter, can be very strong.
Chinese knotweed has strong disease resistance and is usually not prone to illnesses. However, it can be vulnerable to pests and diseases present in its environment. These infections are typically not serious. For care, the plant requires moderate maintenance. It should be pruned regularly to keep a good appearance and healthy growth. Fertilizing can also help encourage flowering. Chinese knotweed is suitable for anyone with an outdoor area, such as a garden or patio, and does not demand a lot of care experience. It may need more attention if grown indoors.
How to keep Reynoutria Multiflora.
Light
Originating from open habitats like meadows and grasslands, Chinese knotweed is a perennial herbaceous plant that prefers the sun. It thrives best in full sun exposure, although it can also survive in areas with partial sunlight.
Temperature
The indigenous habitat of Chinese knotweed is in areas having a moderate temperate climate. It thrives best in temperatures ranging from 59 to 100.4°F (15 to 38℃). To promote the best growth, match the temperature to mirror its natural conditions based on the season.
Fertilizer
Typically, Chinese knotweed requires only one application of fertilizer in the spring, but for optimal growth, feeding it several times can be beneficial. It's advisable to nourish it every four to six weeks. The fertilization process not only improves the look and functionality of the leaves, ensuring stable color and good texture but also encourages the development of roots and promotes the absorption of nutrients, thus maintaining the plant's health in the long run.
