Cultivation method of Christmas Kalanopsis
Looking at other people's Christmas cabbage blooming star-like flowers, do you also itch? This succulent plant, known as the "Winter Elf", can easily grow and fail to bloom if it is not properly maintained. Don't worry! Today, let's talk about the core key to the healthy growth of Kalan cabbage. Three elements of environmental regulation 1. The selection of soil is very particular. Although Christmas cabbage has no strict requirements on soil, if you want it to burst into flowers, it is recommended to use a ratio of pearlite + legular soil + coarse sand of 2:3:1. This mixed substrate can perfectly balance water retention and air permeability, making it especially suitable for the development of fleshy root systems. 2. Temperature control should be accurate to maintain the optimal growth temperature of 18-23℃ in spring and autumn. In summer, if it exceeds 28℃, it should be shaded and ventilated. In winter, it should be moved indoors if it is below 10℃. Temperature difference control is the key to flowering. Maintaining the temperature difference between day and night of around 10℃ for 20 days after autumn can effectively promote flower buds. 3. Light management requires wisdom. As a short-day plant, it ensures 4 hours of direct light +4 hours of scattered light every day for the best effect. You can use the "nine in the morning and five in the evening" shading method: receive natural light before 9 a.m. and after 5 p.m., block it with black cloth at other times, and last for 6 weeks. The two key points of daily maintenance are scientific watering to prevent rotten roots. The "three-look watering method" is adopted: look at the leaves (watering them when they wrinkle), weigh the pot (watering them when they become lighter), and insert bamboo sticks (dry and watering them thoroughly). It can be watered every 20 days in winter, and the effect is better when combined with potassium dihydrogen phosphate foliar fertilizer. The pest and disease prevention system sprays garlic water (diluted 1:20) on the backs of leaves every month to prevent pests. Aphids are immediately killed with cotton swabs dipped in alcohol. In the early stage of powdery mildew, baking soda solution (5g/liter of water) can be sprayed every week, and in severe cases, it can be used alternately with biopesticides.
In fact, maintaining Christmas cabbage is not complicated. Remember the twelve words of "controlling light to promote flowers, controlling water to nourish roots, and controlling temperature to protect your lives." Now is its peak growth season. Hurry up and adjust its maintenance methods and believe that you will be able to harvest your own flowers soon! FAQ: Q: Why are the leaves red? A: Due to strong light or low temperature, it can be recovered by proper shade. Q: How to extend the flowering period? A: Maintain a constant temperature of 15℃ after flowering, stop applying nitrogen fertilizer and increase applying phosphorus and potassium fertilizer.
