Caring for Succulents After Winter
This article introduces the care for succulents, focusing on post-winter maintenance. Let's delve into the details provided by our editor.
Shortly after winter, with large temperature fluctuations between day and night, and nighttime temperatures occasionally dropping below 0°C, it's still crucial to prevent freezing. It's best not to ventilate for extended periods and avoid placing the plants in areas with air currents.
In spring, a layer of plastic film is often placed over the planting trays in greenhouses, opened only briefly at noon. This method results in plump and vividly colored plants. For small and medium-sized enterprises, ensuring that nighttime temperatures do not drop below 5°C can keep most varieties safe. For locations with heating, that's ideal; for those without, precautions against sudden temperature drops are necessary, and insulation measures should be taken before temperatures plummet.
Epiphytic varieties like Epiphyllum are generally less tolerant of "spring frost" than most terrestrial ones. For most Aizoaceae plants, such as Conophytum, Lithops, and some Crassulaceae "winter" species, it's best to maintain temperatures above 7°C. With the warming weather, the duration of sunlight will significantly increase, and most succulents require ample light during this period, especially spring-blooming varieties.
Certain species are very sensitive to sunlight, such as the Haworthia genus, which doesn't require prolonged intense sunlight. Regarding watering (G-Y), as temperatures rise, gradually increase the amount of water given, avoiding direct watering on the plants, especially for those with绒毛. Simply put, water carefully for those not in the growth stage and maintain sufficient moisture for those in the growth stage.
In terms of fertilization, spring top-dressing should focus on nitrogen-based fertilizers, supplemented with phosphorus and potassium fertilizers, applied frequently in thin layers. It's best to wait for stable temperatures before applying. In the lower reaches of the Yangtze River, fertilizing around April ( Qingming and Guyu) often yields immediate results.
The "out-of-greenhouse" time for succulents should be after April, later in the North China region, as early "out-of-greenhouse" timing can be fatal. For propagation, leaf insertion is common for some Echeveria species in late spring, and stem cuttings are also possible. Spring嫁接 is generally not recommended. If seed propagation is chosen, Cactaceae species can be done at this time, but highly succulent varieties should be avoided to prevent summer high temperatures.
Overall, spring maintenance should include: careful watering, ensuring sunlight, cautious fertilization, and preventing "spring frost".
