What if the orchids never bloom?
As an elegant ornamental plant, orchids do not bloom, which puzzles many growers. This article systematically analyzes the causes of orchids not blooming, and provides professional-level solutions to help you master the core skills of orchid flowering promotion. Analysis of the reasons why orchids do not bloom 1.1 Environmental temperature imbalance 15-20℃ is the ideal growth temperature, and the temperature difference between day and night needs to remain fluctuating by 5℃. If it continues to be higher than 25℃ or lower than 10℃, flower bud differentiation will be inhibited. Spring orchid, Cymbidium and other varieties need to undergo 3 weeks of low-temperature vernalization at 10 ° C. 1.2 The imbalance of nutrient supply is the main reason. It is recommended that students use balanced fertilizers with N-P-K=20-20-20 for a long time, and switch to high-phosphorus potassium fertilizers (N-P-K=10-30-20) in the first two months of flowering., diluted to 2000 times twice a month. Scientific flower promotion tips 2.1 The light control plan accepts 2,000 - 3,000 lux of scattered light for 4 hours a day, blocking light by 70% in summer and 30% in winter. The flowerpot can be rotated regularly to ensure uniform light reception. 2.2 The key points of water management adopt the "see dry and see wet" method, and the moisture content of the substrate is maintained at 40%-60%. Properly control the water for 2 weeks before flowering, and maintain the air humidity of 60%-70%, which can be achieved through tray heating. 2.3 Root health monitoring checks the proportion of silver-white healthy roots every quarter. If it is less than 60%, the pot needs to be replaced. Use a mixed matrix of pine bark + volcanic rock + perlite (5:3:2) to ensure breathability.
By accurately controlling the four major elements of temperature, light, water and fertilizer, and cooperating with regular root maintenance, the flowering rate of orchids can be significantly improved. It is recommended to establish a maintenance log to record key data such as temperature and fertilization, and gradually grasp the rules of plant growth.
