What causes the leaves of the Radermachera sinica to curl?
The Radermachera sinica (China doll) is a plant native to the tropical and subtropical regions of southern China. Its auspicious name symbolizes happiness and peace, which is why it is loved by many people, and many households grow one. However, during cultivation people often encounter curled leaves, which greatly affects the plant's ornamental value. So what are the reasons for curled leaves on the Radermachera sinica? Below, Qinnong Net introduces them to you.
1. Environmental change
A newly purchased Radermachera sinica may develop curled leaves because of a sudden change in environment. Since the greenhouse environment is generally well ventilated and humid, while the indoor home environment is relatively dry, this sudden change in environment can have a major effect on the plant, and in severe cases can even cause the plant to die.
2. Too little watering
The Radermachera sinica likes a warm and humid environment. If it is watered too little, the plant cannot get enough water, and transpiration from the leaves consumes a large amount of water, which causes the leaves to curl. At this point, water should be replenished in time.
3. Insufficient ventilation or light
A major characteristic of the indoor environment is poor ventilation, so during indoor cultivation we should often open the windows for ventilation, or place the Radermachera sinica near a window. In addition, lack of light is also a major cause of curled leaves. Normal plant growth requires sufficient sunlight. Although the Radermachera sinica can tolerate shade, it cannot endure long periods in the dark. So if the indoor light is too weak, you can move the Radermachera sinica to a sunny spot every few days to receive light.
4. Too much watering
Too much watering can also cause curled leaves, and this is also the cause of death for most plants. Once watering is excessive, water easily accumulates in the soil, the growth of the plant's root system is restricted to a certain degree, and root rot occurs. This not only causes the leaves to curl, but if not handled properly the entire plant will die.
The above is the summary from Qinnong Net on the reasons for curled leaves on the Radermachera sinica.
