What should I do if the flower buds fall off?
Cymbidium is elegant and luxurious when it blooms, but a slight careless management during the bud period will lead to the bud disappearance. Mastering environmental control and water management during the development period of flower buds is the key to cultivating perfect flower shapes. This article will systematically analyze the causes of flower bud shedding and provide operable maintenance plans. Analysis of the causes of cymbidium bud shedding. The optimal temperature during the bud development period caused by temperature abnormalities is 12-18℃, and the temperature difference between day and night needs to be controlled within 8℃. When the temperature continues to be higher than 20℃, it will accelerate flower bud differentiation and lead to premature shedding of flower buds. It is recommended to use air conditioners or sunshade nets to control the temperature, especially to avoid direct heating. The harm of excessive watering After the bud is formed, the water requirement of the plant is reduced by 30%. At this time, the substrate is kept moist and not wet. It is recommended to use the bamboo stick detection method: insert the bamboo stick into 2/3 of the pot soil, and water it when the tip of the bamboo stick is only slightly wet after being pulled out. After watering, tilt the flowerpot to drain all the stagnant water from the bottom outlet. Remediation of fertilizer imbalance should be stopped during the flower bud period and liquid fertilizer with a ratio of 3:2 should be used instead, and the dilution concentration should be reduced to the conventional 1/2. If fertilizer damage occurs, soak the basin with clear water for 3 consecutive days for 10 minutes, and cooperate with a fan to enhance ventilation to accelerate fertility metabolism. Tips for watering Cymbidium during the bud period accurately judge the watering timing and observe the contraction state of the false bulb: When the false bulb appears longitudinal folds, it means that the plant has entered a critical point of water demand. At this time, you should choose a sunny morning and slowly water it along the edge of the basin with softened water at about 25℃. It is recommended to use a long-nosed crane neck pot for special watering equipment, combined with a 0.5mm aperture showerhead to ensure uniform and fine water flow. Avoid directly impacting the substrate surface, and control the watering amount per time to 200-300ml/plant.
By accurately controlling temperature and scientifically controlling water and fertilizer, the probability of bud elimination can be effectively reduced by 90%. It is recommended to use a thermohygrometer for environmental monitoring, and maintain the air humidity of 60%-70% during the bud development period. Remember the six-character formula of "moistening roots, stabilizing temperature, and controlling fertilizer" to make the cymbidium bloom perfectly.
