How to Cultivate Euphorbia tirucalli
The editor will discuss how to cultivate Euphorbia tirucalli and some tips for its maintenance, as follows:
Euphorbia tirucalli is known in Chinese as "green jade tree" and is also called green coral or blue coral. It is native to East Africa and belongs to the Euphorbiaceae family, Euphorbia genus. To maintain Euphorbia tirucalli, choose a pot and soil with good ventilation and drainage, place it in a sunny environment, control the temperature between 25 and 30°C, water after the soil is completely dry, fertilize once every 7 to 10 days during the growing season, and use pesticides for treatment in case of diseases or pests. Note that the sap of Euphorbia tirucalli is toxic and requires careful handling during maintenance.
1. Potting Soil
For Euphorbia tirucalli maintenance, choose a clay or ceramic pot with good ventilation and drainage, and select sandy loam that is well-drained, loose, and fertile. A mixture of river sand, garden soil, and decomposed leaf soil can be used to create the growing medium. Place a layer of broken bricks at the bottom of the pot for drainage before planting, and let the soil be exposed to sunlight for 1 to 2 days to sterilize and kill germs.
2. Light
Euphorbia tirucalli is native to East Africa and prefers a sunny environment but dislikes direct exposure to strong sunlight. During the winter and spring when indoor lighting is weaker, it should be placed outside in the warm midday sun. In the summer and autumn when the midday sun is intense, use a shading cloth to provide shade or place it in an area with plenty of scattered light.
3. Temperature
The optimal growth temperature for Euphorbia tirucalli is between 25 and 30°C. In the summer, when temperatures are high, spray water on the plant and its surroundings to cool down. In the winter, when temperatures are low, keep it in a warm indoor area.
4. Watering
Euphorbia tirucalli is a succulent plant with leaves that can store water, so it has good drought resistance. Watering should be done only after the soil is completely dry, stopping when water渗透s out from the bottom of the soil. Do not overwater to avoid积水 that could cause root rot. When temperatures are above 30°C, the plant may be in a semi-dormant or dormant state and requires reduced watering.
5. Fertilization
Fertilizing Euphorbia tirucalli should be done in small amounts and frequently, applying thin fertilizer near the roots to avoid thick fertilizer causing plant burn and damaging the root structure. Apply a diluted liquid fertilizer rich in nitrogen, phosphorus, and potassium once every 7 to 10 days during the growing season, and stop fertilizing when the plant enters a dormant state.
6. Diseases and Pests
When Euphorbia tirucalli is affected by anthracnose and leaf spot diseases, spray with carbendazim wettable powder for treatment. For scale insects, use dimethoate emulsion for spray treatment.
7. Precautions
The sap of Euphorbia tirucalli is toxic and can promote tumor growth. Skin contact with the sap may cause redness and swelling, and if it accidentally enters the eyes, it can lead to temporary blindness. Care must be taken during cultivation.
