What should I do if the golden bell is upside down and the flower buds are dropped?
The inverted golden bell is popular for its unique lantern-shaped flowers, but many flower lovers often encounter the problem of flower buds falling off during the maintenance process. This article will systematically analyze the four key factors that lead to bud shedding, and provide targeted solutions to help you recreate the grand scene of full branches and flowers. 1. Impact of light management on flower bud development 1.1 Hazard mechanism of insufficient light As a short-day plant, the inverted golden bell needs to ensure 4-6 hours of scattered light every day during the flower bud formation period. Insufficient light will directly lead to the inhibition of photosynthesis and insufficient accumulation of carbohydrates in the plant, which is manifested by the stagnation of flower bud development and accompanying excessive growth. Experimental data shows that when the light intensity is lower than 2000 lux, the rate of bud shedding can reach more than 70%. 1.2 Scientific light filling plan In spring and autumn, it is recommended to receive direct light before 9 a.m. and after 4 p.m., and use a 50% sunshade net for protection in summer. In winter, you can receive direct light all day long. In case of continuous rainy days, you can add a plant fill light for 3 hours a day. Pay attention to rotating the flowerpot regularly to ensure uniform light reception. 2. Technical Guidelines for Precision Fertilization 2.1 Diagnostic Criteria for Nutritional Imbalance The imbalance of nitrogen, phosphorus and potassium ratio is the main cause of bud fall. It is recommended to use N-P-K=3-1-2 ratio during seedling stage, and adjust it to 1-3-4 during flower bud differentiation stage. When the leaves appear yellowed but the veins remain green, it indicates magnesium deficiency; if the new leaves are white, they may be iron deficient, and medium elements need to be replenished in time. 2.2 It is recommended to adopt the principle of "thin fertilizer and frequent application" to control fertilization time and concentration, and apply 2000-fold diluted water-soluble fertilizer every 10 days during the growth period. Adding potassium dihydrogen phosphate (800 times solution) during the bud stage and spraying boron fertilizer (0.1% concentration) on foliar surfaces can effectively increase the fruiting rate of flower buds. 3. Intelligent Water Management Strategies 3.1 Soil moisture monitoring techniques use the "knuckle detection method": Insert the index finger into the second knuckle of the soil, and if the fingertip is moist. When the air humidity is lower than 50%, it is recommended to use an atomizing spray can to moisturize the plant 30cm away from the morning and evening to avoid direct spraying of flower buds and causing rot. 3.2 The watering cycle is dynamically adjusted to water once every 3-5 days in spring and autumn, and once in the morning and evening in summer, but the amount of water per time needs to be reduced, and the winter is extended to 7-10 days. It is recommended to use slightly acidic water with a pH of 6.0 -6.5. You can let the tap water stand for 24 hours and then add 2 drops of white vinegar to adjust. 4. Three-dimensional pest prevention and control system 4.1 Common disease identification map The early stage of gray mold is characterized by water-stained spots on the flower buds, and powdery mildew forms white powder on the back of the leaves. It is recommended to use Bacillus subtilis (500-fold solution) for biological control and spray it once every 15 days to be safe and without residue. 4.2 The physical pest control plan can be used to hang yellow sticky insect boards for red spiders, and 10% soapy water can be used to wash the back of the leaves during the outbreak of aphids. Regular spraying with garlic extract (1:20) can form a natural protective layer, which has the dual effects of sterilization and insect repelling.
By systematically implementing the four major strategies of light regulation, precise fertilization, intelligent watering and pest and disease prevention and control, the problem of bud falling in the inverted golden bell can be effectively controlled. It is recommended to record the growth status every month, establish a maintenance log, and dynamically adjust management measures based on plant feedback, so that your inverted golden bell can continue to bloom gorgeous flowers.
