(1) Soil: The most important requirements for raising cactus are drainage and air permeability, and sandy loam or calcareous sandy soil can be selected. Don't choose too fertile soil, it is easy to hurt your roots.

(2) Watering: Summer needs the most water, and it is best to water it in the morning and evening. Never water at noon, it will burn the leaves easily. If it is rainy, then the amount of water should not be too large. As the temperature decreases, the demand for water will gradually decrease. The general principle is to dry thoroughly and pour thoroughly.

(3) Fertilization: You can use decomposed bean cake water, egg water and Bika water-soluble fertilizer. However, it should be noted that enough water should be added, and the concentration should not be too high. It is mainly used in spring and autumn, once every 20 days, and once every half a month if it grows fast. Pay attention to the time, preferably in the early morning or evening.

(4) Temperature: I like warmth, preferably at 20 to 30 degrees. Not cold-resistant, the winter temperature should not be lower than five degrees. In addition, the temperature difference between day and night should not be too big.

(5) illumination: cactus plants are strongly positive, and they all need very strong light to grow well and bloom well. However, some small spherical varieties can be placed in semi-shady places, and their characteristics are somewhat different.

2. Prevention and treatment of diseases

The most vulnerable to rot. First, cut off the infected part, and if it is serious, it needs to be changed. Next, strictly control water and improve ventilation.
