Introduction of succulent plant maintenance skills :
Just after the winter, the temperature difference between morning and evening is very large, and sometimes the night temperature will be lower than 0 °C. It is still very important to do antifreeze work. It is best not to ventilate for long periods of time, and not to place the plants in air convection.
In the spring, the planting troughs in the greenhouse are often covered with a plastic film that opens only at noon. The plants cultivated in this way are full and bright. For SMEs, as long as the night temperature is not lower than 5 °C, most varieties can be safe. It is better to have a cultivation place with heating conditions. If there is no heating condition, it is necessary to prevent the temperature from dropping suddenly. It can be warmed before the temperature drops suddenly.
In general, epiphytic varieties such as sassafras are more resistant to "spring freeze" than most terrestrial species; for most apricot plants, such as flesh cones, raw stone flowers and some sedum For "winter type" species, it is best to control the temperature above 7 °C. As the temperature rises, the lighting time will also increase significantly. Most of the succulent flowers should not be less light during this time, especially the spring flowering varieties.
However, some varieties are very sensitive to light, such as the twelve-genus plant, which does not require long-term intense light. In the water supply, the amount of water should be gradually increased with the increase of temperature, it is best not to directly pour on the plants, especially for some varieties with fluff. Simply put, water that has not entered the growing season should be watered as appropriate, and sufficient moisture should be maintained during the growth period.
In the fertilization process, the topdressing fertilizer in spring is mainly based on nitrogen fertilizer, combined with phosphorus and potassium fertilizer, and thin fertilizer. It is best to wait until the temperature is stable and then apply it. For the lower reaches of the Yangtze River, re-fertilization around April (that is, around Qingming and Guyu) can often receive immediate results.
The "out of the shed" time of succulent flowers should be controlled after April, and the North China region is even later. The consequences of premature "out of the shed" are often fatal. In terms of reproduction, in the end of spring, most of the leaves are inserted in the lotus plant, and stems can be inserted. Grafting is generally not recommended in spring. If planting and breeding, the species of the cactus family can be carried out at this time, while the varieties with high meat quality are not suitable to avoid the high temperature in summer. In general, spring maintenance should be done: watering as appropriate, ensuring light, careful fertilization, and preventing “spring freezeâ€.
