How to grow a Radermachera sinica (China doll)? Growing methods and precautions
The Radermachera sinica is one of the most useful potted plants; it can absorb harmful substances from the air and has an anti-radiation function. Many people also grow Radermachera sinica in their offices. So how do you grow a Radermachera sinica? What are the growing methods and precautions for the China doll? Below, the editor will explain how to grow a Radermachera sinica.
Temperature: The growing environment of the Radermachera sinica is also very important, mainly the temperature. The daytime growing temperature is 20°C-21°C, and at night it is 18°C-19°C. In the hot midsummer, try to keep the temperature below 27°C. When the ambient temperature is very high, appropriate shade should be provided with a shed. Increase the ambient humidity to raise the humidity on the leaf surface. In winter, the temperature must not be lower than 8°C, and the humidity must not be less than 5°C, otherwise it will suffer frost damage.
Light: Light is very important. The Radermachera sinica likes to grow in a semi-shaded environment, and full light is also acceptable. When it sprouts in spring, only appropriate watering is needed, which can inhibit the Radermachera sinica from growing too tall. In hot seasons, water should be sprayed 2-3 times a day to prevent heatstroke; increasing spraying on the plant will create a cool and moist environment.
Soil: When growing a Radermachera sinica, the soil is also especially important. It is best to choose a loose, breathable, well-draining and nutritious soil. Usually, use garden soil : leaf mold : decomposed organic fertilizer : river sand = 5:3:1:1 to prepare the mix. During the growing season, loosen the soil once a month to ensure the roots are always in a well-aerated state. If water accumulates in the pot, drain it as soon as possible, and after the potting soil dries out, repot and replace the soil.
Potting soil: For the potting soil of a potted Radermachera sinica, it is advisable to use a loose, fertile, well-draining, organic-rich acidic sandy loam, which is also the potting soil requirement for most indoor flowers. If the soil is heavily sticky or has low acidity, it will cause the leaves of the plant to turn yellow and the sprouting and renewal to decline, thereby affecting the plant's lifespan.
Watering: During the spring and summer growing seasons of the Radermachera sinica, always keep its potting soil moist, and frequently spray water on the leaves and the growing environment to maintain good air humidity. In addition, when watering, some vinegar can be added to increase the acidity of the soil. Especially in the case of northern soil, which is relatively lacking in acid, vinegar can be added to the water to adjust the acidity of the soil.
