How to raise cactus: the watering time is different in each season

Cactus is a perennial succulent and pulpy herb of cactus family. The stem is spherical or oval and green. Many small balls often grow on the side of the ball. It has beautiful and elegant shape and beautiful color. It is easy to cultivate and is deeply loved by people. In the home bonsai, there are often cactus figures. How should cactus be raised? Let's have a look.

Cultivation method of cactus potted cactus 1. Soil requirements: cactus is suitable for dry environment. Therefore, it is required to use sandy soil with good drainage, air permeability and calcareous content. It can also be configured with organic soil, such as 2 parts of sandy loam and rotten leaf soil, 3 parts of coarse sand, plus 3 parts of lime gravel and aged lime wall debris. When planting, it is best to put a small amount of broken bricks and tiles at the bottom of the basin to facilitate drainage; In general, the soil must be loosened frequently after planting, so that the basin soil can easily absorb enough water evenly. 2. Planting method: it is best to plant the upper pot in early spring. The flowerpot should not be too large. It is appropriate to accommodate the ball and have a slight gap. The flowerpot is too large and can not be absorbed after pouring enough water. The air in the pot is blocked, which is easy to cause root rot. The planting should not be too deep, and the spherical rhizome should be flat with the soil surface in the basin.

3. Watering Essentials: watering should be carried out in the morning and evening in summer, before noon in winter, and morning and evening in spring and autumn. Generally, do not pour water from the top, otherwise there will be ugly spots on the ball over time. Summer is the growth period of cactus, and the temperature is high and the water demand is large. Sufficient watering must be ensured. Watering should be controlled during winter dormancy, but not too much, so as to keep the basin soil not too dry. The lower the temperature, the more it is necessary to keep the basin soil dry. 4. Fertilizer application: the potted cactus can also be properly applied in the growing season. The fertilizer can be fully decomposed thin liquid fertilizer, which can be applied every 10 ~ 15 days. Pay attention to the control of fertilizer and water after autumn. Generally, it can be applied once a month, and the fertilizer will be stopped in early October. If the fertilizer is not controlled and the cactus continues to grow, the soft sphere is vulnerable to freezing damage during overwintering. 5. Temperature requirements: Cactus likes high temperature and dry environment. In winter, the room temperature should be kept above 20 ℃ during the day and not lower than 5 ℃ at night. Too low temperature is easy to cause root rot. 6. Light requirements: Cactus requires sufficient sunshine, but it can not be exposed to strong light in summer, so it needs appropriate shade. Indoor cultivation, light irradiation can be used to ensure the demand of growth itself for light and make it grow healthily.

Precautions for cultivating cactus 1. Do not water the newly potted cactus to avoid root rot, but spray it with a watering can.

2. In winter, with the increase of temperature, the plant will gradually break away from dormancy, and the number and amount of watering can gradually increase.

3. For those cactus with depression at the top, pay attention not to pour water into the depression to avoid decay. Pay more attention to watering in the evening.

4. When fertilizing, pay attention not to stick to the ball. If it does, spray it with water immediately.

6. Note that the root osmotic pressure of palm flowers is very low, and the fertilizer and water must be diluted and thin. Do not be thick and fat.
