How to raise Clivia in winter?
Fertilize soil or land
Clivia needs more nutrients in winter, so it is very important to apply winter fertilizer well. Before moving indoors, apply cooked soybeans, fried sesame seeds or compound fertilizer. Move indoors and apply fertilizer every 15~20 days. You can water the roots with the soaking liquid of animal manure. In short, fertilization should adhere to the principle of "decomposition and light application" to avoid fertilizer damage.
water
Clivia has fleshy roots and is afraid of water accumulation; Waxy layer, water is not easy to evaporate. So don't water too much. In winter, the temperature is low and evaporation is slow, so water less. It is necessary to combine water and fertilizer, water after fertilization, keep the basin soil moist, and avoid flooding.
thermal insulation
Clivia grew well in 15~25℃, stopped growing at 10℃ and was frozen at 0℃. Therefore, heat preservation measures must be taken in winter to prevent plant frostbite. After the arrow is drawn, the temperature is maintained at 65438 08℃. If the temperature is too high, the leaves will become thinner, the flowers will be small and the flowering period will be short. When the temperature is lower than 18℃, the flower stems are short and bloom early, which affects the appreciation.
aim at
Clivia likes scattering light, and winter is just right. In winter, move the flowerpot to a well-lit room. Especially before flowering, it is necessary to ensure sufficient light, which is conducive to budding. Proper cooling and ventilation after flowering is beneficial to prolong flowering period.
Leaf protection
The robustness of leaves is the basis of flowering. To keep the leaves strong, we must keep them clean. The specific method is as follows:
First, clean the leaves and spray them with clear water to keep them clean.
The second is to spray fungicides in time to prevent the occurrence of leaf spot.
Clivia cultivation method
Living habits: like sunny and humid environment, avoid dryness, fear of heat and cold.
Soil: For the soil with thick and good drainage, humus soil and river sand are mixed at 4: 1 to make nutrient soil, or special clivia soil is used.
Illumination: It is a semi-negative plant and does not need strong light during its growth. Avoid direct sunlight in summer and shade properly, which is beneficial to leaf growth; In winter, strong light will shorten the flowering period, while medium and strong light will prolong the flowering period.
Temperature: like cool, avoid high temperature, the suitable growth temperature is 15~25℃, above 30℃ will cause excessive growth, below 5℃ will stop growth.
Humidity: Clivia should always maintain a relative environmental humidity of 50~75. When it is less than 50%, the tip of the blade will be scorched, so it is necessary to spray water frequently, generally every day 1 time. If there is heating in winter, it is necessary to increase the air humidity, otherwise it is not conducive to growth and development. Always wipe the dust off the leaves with a wet cloth and keep them clean. Doing so can increase the luster of leaves, be beneficial to growth and prevent pests and diseases.
Water: I like to be wet. Keeping the basin soil moist is beneficial to growth, but it is necessary to prevent water accumulation and root rot. The water demand is different at different growth stages, and the water demand at seedling stage is small, so watering should be less; More water is needed during the arrow drawing period, so more water should be poured; Water more in spring and summer and less in autumn and winter.
Fertilization: add decomposed cake fertilizer when releasing the pot, and apply nitrogen fertilizer every half month during the spring growth period; Apply phosphate fertilizer once a week when drawing arrows; Stop fertilization in summer and when the temperature is lower than 10℃. Avoid applying thick fertilizer and raw fertilizer.
Pruning and shaping: Clivia is a succulent herb and generally does not need pruning and shaping. Care should be taken not to damage the leaves during planting, which will affect the normal growth of Clivia.
Propagation method: sowing propagation and ramet propagation can be used. Sowing and propagation: spring is the best time, and the optimum temperature for germination is 20~25℃. It can be transplanted into a pot about 3 months after sowing, and it can only bloom after 4~5 years of cultivation. Propagation by plant division: take out axillary buds from axillary leaves of adult mother plants, take them out when they grow to 6-7 leaves, cover them with fine furnace ash, plant them with fine sand, keep the room temperature at 20-25℃, and put them into pots after rooting.
Pest control: Common diseases are white rot and soft rot, and common pests are scale insects. Bacterial blight: 50% carbendazim wettable powder can be sprayed with 500~600 times of liquid to prevent and control it. Soft rot: scrape off the rotten part with a disinfection knife, and then spray penicillin or oxytetracycline 4000~5000 times water solution. Scale insects: 40% omethoate EC 1000 times can be sprayed.
Placement: it has strong air purification function and is suitable for placement in living room, study, window sill and balcony.
