My Kangping Shouye is shrinking? How to save it?

The basic requirements of succulent plants for soil are: loose and breathable, good drainage and water retention performance, containing a certain amount of humus, moderate particle size, not containing too much dust, weak acid or neutral (a few species can be slightly alkaline). Succulent plants must be replenished with water in time to meet the needs of growth and development, which is by no means what some people think is "rather dry than wet". Of course, for plants planted in the ground, the number of watering can be less. Most succulents and cactus varieties cultivated by themselves are difficult to master watering, mainly in the timeliness of watering.

To master the watering technology of succulents, we must first understand the dormancy habits of various species. Watering during dormancy is easy to cause plants to rot. For example, watering dormant raw stone flowers in summer will cause plants to rot immediately. If watered in winter, cactus will cause root rot or be easily frozen. Although it may not rot in winter, it will rot in spring.

Secondly, we should carefully observe the growth of each plant. Some people think that some plants are short of water when their leaves are red and their tips and old leaves are dry. In fact, this phenomenon may occur when the light is too strong, the basin soil is short of water for a long time, the root system is destroyed, the root neck is rotted, and the root neck is automatically repaired and scarred after being bitten by insects, resulting in poor water transportation. Therefore, mastering watering technology is very helpful to be familiar with the growth of plants. Generally, plants with particularly vigorous growth and plants in flowering bud stage have higher requirements for water, so they should be watered as soon as possible. However, some old bulbs that basically stop growing need less watering times.

Finally, watering should consider temperature, air humidity, greenhouse ventilation, the size and material of the basin, whether the roots extend down to the sand bed, etc. To help judge whether the basin is short of water. When cultivating other potted flowers, it is generally possible to decide whether to water them according to whether the soil on the surface of potted flowers is white, but in succulents, this judgment will lead to errors, because the cultivated soil of succulents is generally mixed with sand, vermiculite, pebbles, shell powder and other substances, which is easy to cause the surface of potted flowers to be white. Especially in the case of a large proportion of these substances, the surface of the basin soil is often white the next day after watering, and the basin soil below is not short of water at this time. Some experts pointed out that when the surface of the basin soil is dry at 1 cm and the lower basin soil is still wet, the absorption of fleshy roots reaches the maximum. If you water the soil as soon as it turns white as usual, it will cause too much watering and affect the growth of plants.

The watering time should be early morning in summer, before noon on sunny days in winter, and in spring and autumn. In general, don't spray water from above, otherwise there will be ugly spots on the sphere after a long time, the hair of hair column type will be easily polluted and bonded, and the accumulated water at the growing points such as Cui Hua palm will cause rot. Pond water tends to grow algae on plants, which is as ugly as moss. Under normal circumstances, watering must be sufficient, so loosen the soil frequently so that the basin soil can absorb enough water evenly.
