Euphorbiaceae, Euphorbia.
Origin: tropical desert areas of East Africa and South Africa.
Bachelor tree
Soil: Suitable for sandy loam with good drainage. Coarse sand, humus soil, cinder and shell powder can be used to prepare culture soil according to the ratio of 4∶3∶2∶ 1.
Fertilization: topdressing decomposed liquid fertilizer and phosphorus and potassium fertilizer once every 15 ~ 20 days.
Moisture-proof: resistant to dry environment. The soil in the basin remains moderately dry. The principle of spring watering is "see dry and see wet"; In winter, the soil is "dry, not wet"
Temperature: I like warmth. The optimum growth temperature is 20 ~ 30℃. Put it indoors in winter and keep it at 5 ~ 10℃ for safe wintering.
The bachelor tree once had leaves. Due to the hot climate, drought and little rain, the evaporation is large. In the process of adapting to the natural environment, after long-term evolution, the leaves of the bachelor tree are getting smaller and smaller, and then gradually disappear. No leaves can effectively reduce the evaporation of water in the body and avoid the danger of death due to drought.
Light: I like light, but I am also tolerant of semi-shade. Sufficient sunshine is needed during growth. Although the bachelor tree has no green leaves, its branches contain a lot of chlorophyll, which can replace the leaves for photosynthesis, produce nutrients for plant growth and ensure the survival of the bachelor tree.
Pruning: frequent combing and pruning of dense branches, cross branches and old branches to promote the germination of new branches and make the plants beautiful and plump.
Propagation: Cutting propagation.
Pest control: the white milk in the trunk of the bachelor tree is highly toxic, which can resist the invasion of viruses and pests and reduce the occurrence of pests and diseases.
