How to raise the latest cactus

Cactus is a relatively common plant, it is a typical tropical plant, can adapt to a variety of environments, breeding methods are relatively simple, the role is also more extensive, many people like to cultivate cactus at home. So how to raise the cactus? Let's get to know it with the editor.

1. Soil selection

Soil is the place where plants grow, and most of the nutrients and water absorbed by plants come from soil, so soil is directly related to the growth and development of plants. The requirement of cactus for soil is not high, but if it is potted calcareous sandy soil or sandy loam with good drainage permeability, and the soil which is too fertile and contains too much soluble salt, it is easy to cause cactus root rot and damage. The proportion of culture soil can be adjusted according to the variety, plant size and climatic conditions of cactus, for example, young plants need a large amount of nitrogen fertilizer and water during the growth period, and the proportion of rotten leaf soil in the culture soil should be appropriately increased; in areas with more Rain Water, it is necessary to increase the proportion of river sand and maintain good permeability.

2. Fertilization

Cactus needs proper fertilization in the growing season, especially for grafted seedlings with well-developed roots of seedlings and rootstocks, topdressing can use mature bean cake water, pay attention to the concentration, too low concentration is not effective, too high concentration is easy to burn roots. For some cactus that like calcareous soil, lime water can be applied 3-4 times during the growing period to avoid soil acidification and promote its growth.

3. Watering

The drought tolerance of cactus is well known, and it can grow in the desert Gobi, so it should be watered reasonably according to the type of period, season and plant size, so as to avoid plant atrophy or premature senescence caused by excessive lack of water. Watering should be proportional to the temperature, in summer high temperature, evaporation is large, every morning and evening should be watered once, rainy season humidity is large, evaporation is small, in order to keep the soil moist, so as to avoid stagnant water retting roots. Watering should be strictly controlled in winter to keep the soil from being too dry. The lower the temperature is, the more dry the soil should be, so as to avoid root freezing damage. After overwintering, it is necessary to master the principle of wet, dry and thoroughly irrigated enough to meet the requirements of cactus dormancy release and growth recovery.

4. Temperature and light

Cactus is suitable to grow in an environment of 20-30 degrees, with a maximum of 35 degrees and a minimum of 5 degrees. If you keep the temperature above 5 degrees in winter, you can survive the winter safely. The temperature in winter should be relatively stable, and the excessive temperature difference between day and night can easily cause frost damage. When the temperature is more than 15 degrees in spring and more than 35 degrees in summer, it will enter the dormant state and resume growth after autumn. Cactus is a light-loving plant, which is strongly positive and can make its flowers bloom brightly under strong light conditions, so it is necessary to supply sufficient light, especially in winter.
