2. The bachelor tree needs to change the pot soil every 1-2 years, mainly with new loose sandy loam. When the bachelor tree grows to a certain period, the pot soil should also be replaced.
3. The bachelor tree is drought-tolerant, salt-tolerant, wind-resistant, barren-resistant, and likes plenty of sunshine. The key to flowering is to put it in a sunny place all year round, but avoid exposure to the sun.
4. When the bachelor tree enters the dormant period in winter, fertilization should be stopped. If the temperature is low, fertilization is easy to cause root rot. In the growing season, the cooked dilute liquid fertilizer containing nitrogen, phosphorus and potassium should be applied every 7- 10 days, and it should not be too concentrated.
5. The bachelor tree is prone to carbon disease and leaf spot disease, so it needs to be sprayed with thiophanate-methyl wettable powder. If the indoor ventilation is poor, the stems and leaves of the bachelor tree are prone to scale insects, so it is necessary to spray omethoate emulsion. See the drug instructions for details. Remember not to water too much, which will easily lead to root rot, yellow leaves, and even gray mildew spots, which will rot in severe cases. Pay attention to ventilation and drainage. When the condition is serious, carbendazim powder can be sprayed.
