Temperature management method of succulent plants in spring

In spring, the temperature varies greatly in different parts of China, and the climate in early spring and late spring is also very different. Therefore, the spring management of succulents should be carried out according to the climate and time in different regions. In addition, there are many kinds of succulents and their habits are quite different. It can be roughly divided into winter species that grow in cold seasons such as late autumn, winter and early spring, and sleep at high temperature in summer, such as Piaodao, Dong Yun, Black Mage, Taomei and Sedum hydroponicum. Lilac, Dianthus, Magic Jade, Imperial Jade; Sedum lineatum, Eupatorium tuberosum, Welsh onion, spring grass, hyacinthus orientalis; Jade Fan, Vientiane, Yulu, Cao Bao, Aloe Keruihe, South African Tortoise Shell of Dioscoreaceae.

African gourds, sleeping bags and laughing bags of Cucurbitaceae; Passion flower's weeping wine jar and thorn vine; Mexican tortoise shell of Dioscoreaceae, etc.

Types of Sedum, such as gorgeous posture, flowers and the moon. Therefore, spring management of succulents should be carried out according to different types.

Temperature management of succulents in spring;

After beginning of spring in February, the daytime temperature in South China can reach 10℃~ 15℃, the indoor temperature can reach above 20℃ in sunny days and 3℃~5℃ at night. In this season, the temperature difference between day and night is relatively large, and the succulents in the greenhouse begin to grow vigorously, especially the winter and intermediate succulents, which is the fastest growing stage in the whole year. But at this time, the temperature is still unstable, and cold currents often appear. Don't rush to move it out of the house or open the greenhouse, so as to avoid the freezing damage caused by the high and low temperature, and also prevent the water droplets in the greenhouse from condensing and dripping on the plants to cause rot. However, the northern region is still frozen and snowy, and the management of succulents is mainly based on heat preservation, cold protection and light enhancement. It is best to keep the temperature above 5℃ at night, and there is a certain temperature difference between day and night.

In March, the temperature in Yangchun continued to rise, and the temperature difference between day and night increased. Winter and intermediate succulents have entered the peak season, and succulents have begun to wake up in summer. At this time, you can open the window of the greenhouse for ventilation, so that plants can gradually adapt to the outdoor environment, especially when the weather is fine in the south, and avoid steaming plants because of the high temperature in the greenhouse at noon. However, in case of cold current, late spring cold or strong wind cooling in the northern region, doors and windows should still be closed to avoid freezing damage to plants. With the temperature rising in April, summer species and intermediate succulents of Agavaceae, Cactus, Euphorbiaceae, Araceae, Sedum and Aloe can gradually move outdoors. However, in case of continuous rainy days, attention should be paid to prevent long-term rain, so as to avoid low temperature and low humidity leading to plant rot. When the indoor temperature exceeds 30℃, open the window for ventilation and cooling.
