How to Grow and Care for the Happiness Tree (Radermachera sinica)

The happiness tree is also called the bean tree, green treasure and so on. It is a natural air purifier and symbolizes happiness and peace, making it deeply loved by the public. So, how do you grow a happiness tree? Let's find out together!

1. Lighting in the greenhouse

The greenhouses that flower growers build nowadays are mostly of the full-light type, meaning sunlight can shine throughout the entire greenhouse. Although the happiness tree can be grown under full light, strong light will still cause its leaves to turn yellow, so when flower growers build a greenhouse, the light-transmitting material on the roof should be chosen with poor light transmission, which can effectively avoid the scorching light at noon. Secondly, the surroundings should be as flat as possible, with no taller objects blocking the slanting sunlight, and in the hotter summer months shade material should also be prepared.

2. Temperature control

The happiness tree is relatively more resistant to high temperatures; low temperatures are harder for it to endure. So in summer the temperature should be kept within 30 degrees; above 30 degrees the happiness tree will stop growing, and at this point ventilation and cooling need your attention. In the cold winter, the planting density of happiness trees can be reduced to provide some insulation. Generally the winter temperature should be kept above 8-10 degrees and not exceed 15 degrees; this temperature range is when it grows fastest in winter. Too high a temperature will break its inherent growth pattern and is not conducive to cultivating high-quality happiness trees.

3. Choosing fertilizer and water

Fertilizer and water have a relatively low impact on the growth of the happiness tree, so flower growers do not need to worry too much about abnormal growth caused by fertilizer and water problems. In terms of its growing environment, the happiness tree prefers semi-dry soil, so when watering, stick to the principle of small amounts and few times; keeping soil moisture above 50 is enough. Fertilizer can be applied once every 3-4 months; during the fast growth period the fertilizing interval can be appropriately shortened. If you want to speed up its absorption, you can apply the fertilizer mixed with water.

4. Pest and disease prevention

Pests and diseases are always an aspect that must be taken seriously, and the diseases the happiness tree suffers from are basically insect pests. The common ones are probably scale insects and the like, which mostly appear where the branches and leaves meet. When growing them, check by looking through the joint of each plant so problems can be found and dealt with in time. Once found, remove the insects promptly, check whether any eggs remain, and spray with an insect-resistant and insect-killing spray.

The happiness tree is a very good indoor green plant; it can be grown well both at home and in the office. The above is a little knowledge on how to grow a happiness tree compiled for you by the editor, and I hope it can help you!
