1. Soil: The most important requirements are drainage and air permeability. 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, so 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 the decomposed bean cake water, egg water, etc., which can be prepared by yourself. 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, and it is best to be 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.

Second, breeding cactus should prevent and control diseases.

Cactus is most susceptible 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.

Propagation method of cactus

When cactus is planted at home, it is often propagated asexually, that is, by dividing plants, cutting and grafting.

1. ramet

Most cactus flowers are easy to divide into seedlings or bulbs, and it is easy to survive if they are pulled out and planted separately. For some varieties that are not easy to divide into balls, it can be forced to breed balls by cutting off. That is, the upper part of the stem of the mother plant is cut off (the cut-off part can be used as grafting or cutting cuttings), so that it loses its upper growing point and can no longer grow upwards. Strengthening the management of water and fertilizer can grow new bulbs. ?

2. Cutting

Most cactus cultivated at home are propagated by cutting, and the survival rate is extremely high. Cutting time can be in spring, summer and autumn. When cutting, young stems should be selected. After cutting the stems from the mother plant, they should be placed in a semi-shady and ventilated place for 5-7 days. When the incision is dry and the cortex shrinks slightly inward to form a film, cutting should be carried out again. The cutting length is 10 cm and the cutting depth is 3 cm. Insert it into sterilized sandy soil, and water it after the second day. When watering, it can be slightly wet to prevent the cuttings from rotting. Cactus generally takes root after 20 days of cutting.

The flower language of cactus is-strong.
