Does Mo Lan have to change the basin every year?
As a traditional and precious orchid variety in China, Moran is deeply loved by gardening enthusiasts for its elegant flower appearance and unique aroma. However, in daily maintenance, many orchid friends are often confused by the frequency of basin replacement. Does this orchid plant need to be changed every year? How to master the correct basin changing cycle? This article will combine professional cultivation experience to provide you with a detailed analysis of the key points of changing pots of Cymbidium. The necessity of changing pots is analyzed. The root growth characteristics determine the requirements for changing pots. The developed fleshy root system of Cymbidium has an alarming growth rate. Experimental data shows that the annual increase of root system of healthy plants can reach 2-3 times the original volume. This growth characteristic requires growers to change pots regularly, otherwise the coiled root system will form a "root cage", resulting in reduced substrate permeability and hindered nutrient absorption. Scientific pot changing cycle recommendations According to statistics from China Orchid Association: 1. Pots with a diameter of less than 20cm need to be replaced every year. 25-30cm medium basin can be replaced in 2 years 3. Special root-control pots can be extended to 3 years. It is recommended to combine plant growth. When exposed root systems are found in the drainage holes at the bottom of the basin, it is the best time to change pots. Practical Guide for Changing Poins of Murchids The Golden Rule for Matrix Ratio recommends using the "3322" formula: 30% pine bark (0.5-1cm particle size) 30% volcanic rock 20% peanut shell 20% water moss This ratio has been verified for many years to ensure that the substrate has both water retention and air permeability, and the pH value is stable in the optimal growth range of Murchids of 5.5-6.5. Five-step method for plant dividing and pot changing 1. Remove the basin after 7 days of water interruption. 2. Keep 1/3 of the protective soil 3. Trim the rotten roots (the incision needs to be coated with charcoal powder) 4. Lay a 3cm ceramsite layer at the bottom of the new basin 5. After planting, place it in a suspended place in a shade to slow down seedlings after pot change Key maintenance points Three stages: Week 1: Maintain environmental humidity at 70%, prohibit fertilization Week 2: Start accepting morning scattered light Week 3: Return to normal maintenance, add dilution 3000 times liquid fertilizer By scientifically mastering the pot change cycle and operating skills, it can not only avoid stiff seedlings of Cymbidium, but also effectively improve the quality of flowering. It is recommended that growers establish a maintenance log to record the time and plant response of each pot change, and gradually find out the most suitable pot change plan for their own environment.
