The potted Hedysarum is suitable for soft and fertile soil with good drainage, and the best fertile soil with more humus content is planted. It can be used for saprophytic soil, vegetable garden soil, pond soil, etc. The soil should be kept properly moist, which is good for the growth of plants.
The temperature suitable for the yellow flower is about 18-25 ℃, the flower can stand the cold, but the winter temperature is better to keep above 6 ℃.
Yellow Hedysarum like a warm and humid environment. It grows best in a semi shady space. Pay attention to avoid the direct sunlight of the sun. When the sun is strong in summer, shade the leaves properly to avoid sunburn. Generally speaking, block about 50% of the light. If possible, it can be directly planted in the shade of trees or higher flowers.
Hedinglan likes to be wet and drought resistant. It needs to be watered more during its vigorous growth period, but it is forbidden to accumulate water in the basin. In summer, especially to maintain the humidity of its growing environment, in addition to maintaining the moisture of the soil, we should often spray water around the flowers to improve the humidity of the surrounding air. After the flowering period, hedynia will enter a short dormancy period, at this time, the root function of the plant will decline, the absorption capacity will be greatly weakened, so it is necessary to control the watering and reduce the water quantity. When the air is dry, spray water on the leaves frequently to keep the leaves moist.
In the growth period of hedinglan, the fertilizer should be mainly decomposed organic fertilizer once every two to three weeks. Before the flowering period, the fertilizer should be changed to phosphorus and potassium as the main fertilizer. After the flowering period, cut off the remaining flowers in time to reduce the loss of nutrients. Stop fertilizing after the temperature drops in autumn and winter.
The common diseases and insect pests of hedinglan include white silk disease, anthrax, scale insects and so on. These diseases and insect pests are especially easy to cause in the hot and humid environment in summer. Therefore, in the process of daily maintenance, we should pay attention to prevention. In addition to frequent sterilization and disinfestation, it is more important to create a good environment for the growth of plants, eliminate the main causes of diseases and insect pests, and fundamentally eliminate diseases and insect pests.
