The Radermachera sinica (China doll) is actually very easy to care for. Do these few things well, and its branches and leaves will grow like crazy and stay glossy green.
How should you care for a Radermachera sinica to make it thick and vigorous? Today let's discuss this question together. The Radermachera sinica, whose flower meaning is peace and happiness, is a tree that symbolizes good fortune. Generally, for small cuttings, the first step is to acclimatize the seedlings. Once the seedlings have recovered, the root system has developed, and new buds have appeared, you can pinch off the growing tips and fertilize to make its branches and trunk sturdier, and only then will it grow well.
1. Soil
The Radermachera sinica likes moist, loose soil, so you must use breathable, fertile soil to grow it. You can use peat soil, perlite, and vermiculite mixed in a 4:1:1 ratio, or you can mix leaf mold, large-particle river sand, and garden soil, and you can also add one part pine needle soil to make the soil slightly acidic. Only when the soil is loose and breathable will keeping it moist after watering more not cause root rot.
2. Fertilizing
You also need to water and fertilize regularly. Use a fertilizer mainly based on nitrogen and potassium once or twice a month to supply the tree's needs, so that the tree can grow vigorously.
3. Pinching off the growing tips
The Radermachera sinica grows relatively fast. Be sure to remember to pinch off the growing tips of newly grown branches. Pinching off the growing tips promotes the thickening and aging of the branches, and this can also differentiate more side buds and side branches, making it lush and leafy.
The Radermachera sinica likes a warm, humid environment. Its growing temperature is around 20 degrees, and it needs relatively high air humidity. On the premise of ensuring ventilation, mist it with water once every two or three days, and give it a certain amount of scattered light, and you can grow it very well.
One more thing to note is that every one to two months, supplement it once with ferrous sulfate to ensure the acidity of the soil and avoid the phenomenon of yellowing leaves and leaf drop. A Radermachera sinica cared for this way will be glossy green every day, shoot up like crazy every day, and grow especially fast.
