How to raise newly purchased spring orchids
As a traditional and famous flower in China, newly purchased plants require particularly careful maintenance and management. Newbies who are new to orchids often cause damage to the plants due to improper maintenance. This article will systematically explain the five core maintenance points from soil configuration to environmental control to help your spring orchids quickly adapt to the new environment. Analysis of the key points of basic maintenance of spring orchid Scientific soil allocation and pot replacement skills The root system of spring orchid has strict requirements on the substrate. It is recommended to use lime soil (60%)+ perlite (20%)+ pine bark (15%)+ plant ash (5%)). The gold ratio. When changing pots, pay attention to retaining 1/3 of the core soil, and use a bamboo stick to gently pick the old soil around it to retain healthy aerial roots. If black rot roots are found, use disinfection scissors to cut at a 45° angle, and apply charcoal powder to the incision to prevent infection. Precise temperature control plan The new seedlings will maintain a constant temperature environment of 18±2℃ during the adaptation period, and the temperature difference between day and night will be controlled within 5℃. In winter, the double-layer basin method is used to keep heat, and in summer, water trays are placed on the ground to cool down through evaporation. Pay special attention to the maintenance of air-conditioned rooms. Plants should be more than 3 meters away from the air outlet to avoid direct hot and cold winds. The intelligent watering management system adopts the "three-look" watering method: at first glance, the surface of the substrate turns white, the weight of the flowerpot is reduced by 1/3, and the three-probe bamboo stick is inserted without moisture. Maintain the substrate humidity at 40%-60% in spring and autumn, combine morning and evening leaf spraying in summer, and use immersion basin method to supply water in winter. Pay attention to strengthening ventilation after watering to prevent accumulated water and rotten roots. The light environment optimization strategy sets a "three-period" lighting plan: receive direct light in the morning (6-9:00), use a 60% sunshade net at noon, and change to the east-facing sill in the afternoon. Use a light meter to monitor and maintain the optimal light intensity of 15,000 - 20,000 Lux. Rotate the flowerpot 45° regularly every month to ensure that the plants receive even light. Precision fertilization schedule Apply water-soluble fertilizers with N-P-K=20-10-10 during the growth period (April to June), and use 7-11-26 high-potassium fertilizers from September to October. Adopt the principle of "thin fertilizer and frequent application", dilute the standard concentration to 1/800, and use EM bacterial solution to improve the fertilizer efficiency. Observe the status of the leaves within 12 hours after fertilization, and immediately rinse the substrate when scorched tips appear.
Through systematic maintenance and management, the survival rate of newly purchased spring orchids can be increased to more than 90%. It is recommended to establish a maintenance log to record daily temperature and humidity changes and plant responses, and gradually grasp the growth laws of spring orchid. Regularly check the back of the leaves with a magnifying glass to prevent diseases such as scale insects, and let your spring orchids grow healthily and bloom every year.
