2. temperature. Happiness tree, as a plant native to tropical areas, likes heat and has poor cold tolerance. The most suitable environmental temperature range for the growth of happiness trees is 20-28 degrees. In summer, if the temperature is higher than 28 degrees, take timely cooling measures and move to a ventilated and cool place; When the temperature drops in winter, measures should be taken in time to ensure that the ambient temperature is not lower than 8 degrees.
3. soil. The substrate of happiness tree should be loose and fertile acid soil with good drainage and permeability and rich humus. Before planting the happiness tree, the garden soil, humus soil, decomposed organic fertilizer and river sand can be mixed according to the ratio of 5:3: 1: 1. If the leaves of the happiness tree fall off, some ferrous sulfate or other compounds containing acidic elements can be mixed into the fertilizer to improve the PH value of the soil, or some peat soil can be mixed into the matrix to reduce the pH value of the soil.
4. Moisture. Happiness trees like humidity, and the humidity of their growing environment should be kept between 70% and 80%. If the happiness tree is cultivated indoors, in order to prevent it from growing too high, the amount and frequency of watering can be reduced appropriately, as long as the soil is kept slightly wet. If you water too much, the root system will have difficulty breathing or even rot, which will cause the plants to fall leaves. If the temperature is too high in summer and the water evaporates too fast, you can spray water on the leaves of plants and the surrounding environment every day. When the temperature is too low in winter and plants enter dormancy, the amount and frequency of watering should be reduced to prevent water accumulation.
5. fertilizer. Happiness trees like chemical fertilizers, and it is best to use compound fertilizers. In addition, liquid fertilizer should be applied once a month during the growing period, and diluted decomposed cake fertilizer can be used. If it is a happy tree cultivated indoors, it can be turned over once in spring. In addition, the contents of phosphorus and potassium in compound fertilizer can be increased appropriately. When the temperature is too low in winter, fertilization should be stopped.
Step 6 trim. Prune the happiness tree regularly every year to keep it beautiful. In spring, after the new buds of the happiness tree germinate, some old, weak, diseased branches and some too dense branches can be pruned.
7. Precautions. In the process of maintaining the happiness tree, the pot soil should be changed once a year to prevent the roots from absorbing nutrients due to soil hardening. As the plant grows, it needs a bigger flowerpot. Potted plants should not be placed next to air conditioning or heating, and rooms with floor heating in the north should be padded with flower stands.
