In order to resist drought, plants in the desert have developed various drought-resistant methods, such as trying to save water, or trying to find groundwater, or reducing water consumption by falling leaves.

In addition to storing water in succulent stems, cactus plants have other unique skills, such as the evolution of leaves into needles, which can reduce the evaporation of water.

Most of their roots are shallow and wide, which can help to find and absorb more wood. The thick round or spherical shape minimizes their exposure to air and sunlight. This is also the lack of methods to reduce water evaporation.

Extended data:

Cactus is most suitable for growing in loose nutrient soil, and the ratio of vermiculite: fine sand: total erosion humus is 4: 4: 2.

The newly planted cactus does not need watering, but needs a small amount of watering after half a month, and then normal watering work is carried out after a new root grows one month;

Give cactus plenty of sunshine when maintaining at home, but at noon in summer, when the sunshine is too strong, give cactus shade to avoid being sunburned by the sun.
