Kalanchoe blossfeldiana is a very popular potted plant with excellent ornamental effects and good ecological environment. However, its propagation is not easy and requires certain skills and patience. This article will detail the propagation methods and precautions for Kalanchoe blossfeldiana, hoping to provide you with reference for cultivating more beautiful and healthy Kalanchoe blossfeldiana.
I. Selecting Excellent Varieties of Kalanchoe blossfeldiana
Before propagating Kalanchoe blossfeldiana, we first need to select excellent varieties. Excellent varieties of Kalanchoe blossfeldiana grow fast, have strong disease resistance, long flowering periods, and bright flower colors. Generally, large-leaved Kalanchoe blossfeldiana and North China Kalanchoe blossfeldiana are very good choices.
II. Collecting Mature Seeds of Kalanchoe blossfeldiana
When propagating Kalanchoe blossfeldiana, we need to collect mature seeds. Generally, when Kalanchoe blossfeldiana seeds mature, the fruit turns black and begins to split open. At this time, we can pick the seeds and wrap them in gauze to dry for at least one week.
III. Cleaning and Disinfecting Seeds
Before sowing, we need to clean the seeds thoroughly and disinfect them with 75% alcohol. This can effectively prevent bacterial and fungal attacks and improve seed germination rate.
IV. Soaking Seeds for Germination
After cleaning and disinfection, we need to soak the seeds in warm water for 24 hours to promote germination. After soaking, we need to take out the seeds and let them dry before sowing.
V. Preparing Seedling Soil
Before sowing, we need to prepare seedling soil. The seedling soil should have good air permeability, water retention, and rich nutrients. We can mix leaf mold, sandy soil, and well-rotted chicken manure, then add appropriate amounts of red soil and vermiculite powder.
VI. Sowing Kalanchoe blossfeldiana Seeds
After preparing the seedling soil, we need to evenly spread the Kalanchoe blossfeldiana seeds on the soil surface and gently cover them with seedling soil. To ensure successful sowing, we can spray some water on the soil surface.
VII. Maintaining Appropriate Temperature and Humidity
After sowing, we need to maintain appropriate temperature and humidity. Kalanchoe blossfeldiana has high environmental requirements and needs to be kept at around 20°C with relative humidity above 60%.
VIII. Proper Fertilization
After the Kalanchoe blossfeldiana grows two or three true leaves, we can fertilize it appropriately. Generally, we can use compound fertilizer or organic fertilizer. Apply once every 10 days or so to promote the growth of Kalanchoe blossfeldiana.
IX. Transplanting Kalanchoe blossfeldiana Seedlings
When Kalanchoe blossfeldiana grows to 6-8 leaves, we can consider transplanting it into a pot. To prevent root damage, we need to gently move the seedling into a new pot and place some sand and vermiculite powder at the bottom.
X. Managing the Growth of Kalanchoe blossfeldiana
After transplantation, we need to pay attention to managing the growth of Kalanchoe blossfeldiana. Kalanchoe blossfeldiana has high light requirements and needs to receive 4-6 hours of sunlight daily. At the same time, we need to regularly water, fertilize, and prune to maintain healthy growth of Kalanchoe blossfeldiana.
XI. Pay Attention to Pest and Disease Prevention
During the growth process of Kalanchoe blossfeldiana, we need to pay attention to pest and disease prevention. Common diseases include powdery mildew, smut, and gray mold. We can regularly spray fungicides and herbicides to prevent disease and pest infestations.
XII. Pay Attention to Timely Repotting
During the growth process of Kalanchoe blossfeldiana, we need to pay attention to timely repotting. Usually, we need to repot in spring or autumn each year. When repotting, we need to remove all the old soil and refill the pot with fresh seedling soil.
XIII. Pay Attention to Controlling Temperature and Humidity
In winter or when the temperature is low, we need to pay attention to controlling temperature and humidity. Kalanchoe blossfeldiana is sensitive to cold environments and needs to be kept above 15°C while maintaining appropriate humidity.
XIV. Regularly Pruning Kalanchoe blossfeldiana
During the growth process of Kalanchoe blossfeldiana, we need to regularly prune it. Pruning can promote branching and reproduction of Kalanchoe blossfeldiana and keep its shape beautiful. However, we need to avoid the flowering period to prevent affecting flower opening.
XV.
The propagation of Kalanchoe blossfeldiana requires certain skills and patience, but as long as the correct method is mastered, healthy and beautiful Kalanchoe blossfeldiana can be easily cultivated. During the propagation process, we need to pay attention to selecting excellent varieties, cleaning and disinfecting seeds, timely soaking for germination, reasonably making seedling soil, maintaining appropriate temperature and humidity, regular fertilization, watering, and pruning to ensure the growth and reproduction of Kalanchoe blossfeldiana.
