Why don't longevity flowers bloom and grow their leaves?
As a deeply loved New Year flower, longevity flowers are popular for their beautiful flower appearance and long flowering period. But many flower lovers have found that plants only grow leaves and do not bloom. What is the reason? This article will help you solve maintenance problems through in-depth analysis of five key dimensions. 1. Imbalanced light regulation leads to excessive growth 1.1 Chain reaction of insufficient light. Longevity flowers are short-day plants that need 4-8 hours of scattered light every day. When the light duration is less than 4 hours, photosynthesis is blocked, and the plant will preferentially allocate nutrients to the leaves for growth, resulting in the phenomenon of "only seeing green leaves but not seeing flowers." Especially during the bud pregnancy period (October to December), it is necessary to ensure sufficient light to stimulate flower bud differentiation. 1.2 The scientific light filling plan recommends adopting the "morning light + afternoon shade" mode: receive full sunshine in the morning and use a sunshade net to filter 30% strong light in the afternoon. Rotating the flowerpot regularly to ensure uniform light reception. Combined with an intelligent timed fill light (filling light for 2 hours per day), the flower bud formation rate can be increased by 35%. 2. The deep impact of the imbalance of nutrient supply 2.1 The key parameters of fertilizer ratio require balanced nitrogen, phosphorus and potassium fertilizers (20-20-20) during the growth period, and should be adjusted to a high phosphorus and potassium formula (10-30-20) during the flower bud differentiation period. Excessive nitrogen fertilizer stimulates chlorophyll synthesis, resulting in inhibition of flowering gene expression when the leaf area index is greater than 3.5. 2.2 Precision fertilization schedule Spring and summer: Apply liquid fertilizer diluted 1500 times every 15 days Autumn and winter: spray 0.2% potassium dihydrogen phosphate every week to appear during bud period: Stop fertilization to avoid bud falling 3. Double-edged sword effect of water management 3.1 Principle of controlling water and promoting flowering Moderate drought stress can increase ABA (abscisic acid) concentration and activate flowering related genes. It is recommended to use the "see dry and see wet" method, pour water thoroughly when the moisture content of the matrix drops to 30%, and cooperate with ceramsite pavement to enhance air permeability. 3.2 Watering technical parameters 5-7 days per time in spring and autumn, 3 days per time in summer (morning and evening), and 10-15 days per time in winter. The water temperature needs to be consistent with room temperature to avoid root damage caused by temperature differences of more than 3℃. 4. Analysis of key points for extended maintenance 4.1 Temperature control strategies maintain the temperature difference between day and night of 8-10℃ (20-25℃ during the day and 15-18℃ at night). Continued low temperatures of <10℃ will lead to flower bud abortion. Opening windows at night can create a temperature difference to stimulate flowering. 4.2 Tips for pruning and shaping cut off the remaining flowers and the next 2 pairs of leaves in time after flowers, and retain 3-4 pairs of strong leaves. Picks 2-3 times during the growth period to promote branching, ensuring that each plant retains 6-8 flowering branches.
Through systematic maintenance and management, about 90% of longevity flowers can reflower within 30-45 days after regulation. It is recommended to establish a maintenance log, record data such as light duration and fertilization cycle, and gradually optimize the maintenance plan so that your longevity flowers bloom year after year.
