What should I do if the orchids don't sprout and look like nothing?
As an elegant ornamental plant, orchids often suffer from problems such as failure to sprout and wilting leaves due to improper maintenance. This article focuses on the four key factors that hinder the growth of orchids, combined with professional horticultural experience, systematically analyzes scientific maintenance methods from germination to growth, and helps flower friends bring orchids back to life. 1. Countermeasures for improper water management 1.1 Watering cycle and water volume control The new bud incubation period must strictly follow the principle of "seeing dry, seeing wet" and adopt the knuckle test method: Insert the index finger into the plant material 2 cm, and pour it thoroughly immediately when it is dry. It is recommended to use a pointed spout pot to slowly inject water along the wall of the basin to ensure that the plant material is evenly wetted. 1.2 In addition to evening spraying, air humidity control techniques can be used to set up a pebble water tray under the flower pot to maintain 60%-70% humidity through moisture evaporation. Pay attention to avoid water droplets staying in the heart of the leaves to prevent bacterial soft rot. 2. Scientific configuration of the lighting system 2.1 Classification management of light intensity receives full sunshine in spring and winter, and uses a double-layered sunshade net (shading rate of 70%) in summer. It is recommended to install a light meter to control the light intensity between 15,000 - 25,000 lux to promote photosynthesis while avoiding sunburn. 3. The golden rule of nutrient supply. How to deal with orchids if they don't sprout? 3.1 Fertilizer ratio plan Use special orchids fertilizer with N-P-K=30-10-10 during the germination period, and switch to 10-30-20 formula during the reproductive growth period. It is recommended to add decomposed sheep manure organic fertilizer (50g/month per pot) to be used with EM bacterial solution for better results. 4. Precise operation of plant trimming 4.1 The optimal pruning period is around the vernal equinox, retaining 3-5 full bud points. Alcohol-disinfected scissors are chamfered at 45°, and charcoal powder is applied to the incision to prevent infection. Combination of brassinolide after pruning promotes wound healing.
By systematically adjusting the four major elements of water, light, fertilizer and shearing, and cooperating with the use of environmental monitoring equipment, the germination rate of orchids can be increased by more than 80%. It is recommended to test the pH value of plant materials every month (ideal value 5.5-6.5), and establish a maintenance log to record growth data, and gradually form a personalized orchid maintenance system.
