How to grow a Radermachera sinica (China doll)? Detailed care methods and tips
The Radermachera sinica (China doll) is a common green plant with excellent air-purifying ability. Many people like to buy two pots and place them in the study, bedroom or office, set in front of the computer desk, very pleasing to the eye. It comes in large and small sizes, suitable for rooms of all sizes, and its cultivation requirements are low, requiring no great skill or cost, making it very suitable as an indoor green potted plant. So how should the Radermachera sinica be grown? Below, Shuaishuai brings you the cultivation methods and precautions for the Radermachera sinica!
I. Cultivation methods
1. Soil
The Radermachera sinica likes loose, fertile soil that drains well, has good aeration and is rich in humus. The soil mix of Radermachera sinica bought directly from outside is generally a mixed soil of garden soil and leaf mold. Perlite or vermiculite can also be added to the soil, which can prevent the soil from becoming compacted.
2. Water: The Radermachera sinica likes a humid environment. During the growing period, it is necessary not only to ensure relatively high ambient humidity, but also to ensure sufficient soil moisture. However, in spring, which is precisely the process of buds and new shoots emerging, water should be properly controlled to avoid leggy branches. In spring, watering can be done once every 2-3 days; in other seasons, watering can be done once a week, and it should also be decided according to the local weather conditions. If it is a sunny day, check whether the soil is dry; if dry, water it. If it is cloudy or rainy, do not water.
3. Temperature and humidity
The Radermachera sinica likes a warm and humid environment. The optimal growing environment temperature for the Radermachera sinica is between 20-30 degrees. If it exceeds 30 degrees, cooling measures should be taken; you can spray water on the plant and around the potting soil, which both increases humidity and lowers temperature, killing two birds with one stone. When the temperature drops below 10 degrees, the Radermachera sinica should be moved into a shed for warmth; if the temperature is below 5 degrees, symptoms of cold damage and leaf drop will occur. Keeping air humidity at 70% to 80% is sufficient. For example, a well-ventilated bathroom with moderate humidity is a very good environment.
II. Precautions
One thing to note for the Radermachera sinica is pests and diseases. The Radermachera sinica is afraid of frostbite in winter, and too high a temperature in summer can easily cause disease. Once small insects are found, we should wipe them off with a damp cloth, then spray pesticide and strengthen ventilation. If the leaves turn yellow, promptly clean up the yellowed leaves and spray a fungicide at a moderate concentration.
The above are the cultivation methods and precautions for the Radermachera sinica. During its growing period, special attention should be paid to the problem of pests and diseases. Especially in the hot and humid environment of summer, bacteria are most likely to breed; such conditions provide a very good growing environment for the reproduction of bacteria, so we should take corresponding protective measures and spray the corresponding fungicide. Insect pests are relatively few, and since they are generally grown indoors, there is no need to worry about insect pests.
