How to prevent the rotten roots of green patina unicorn
As a rare species among succulent plants, the green unicorn is favored by gardening enthusiasts for its unique metallic luster and shape. However, due to its special physiological structure, root maintenance has become a difficult point in planting, especially the problem of rotten roots that often troubles novice growers. Mastering the following five key maintenance tips can effectively improve the survival rate of green green unicorn. 1. Core skills for preventing and controlling green qilin rotten roots 1. The precise water control technology adopts the "see dry and wet" watering method, and uses bamboo sticks to test the substrate humidity before each watering. The irrigation frequency is maintained at 15 days per time in spring and autumn, and the high temperature dormancy period in summer is extended to 25 days per time. Pay special attention to selecting a red pottery pot with a hole in the bottom to ensure that excess water is drained within 30 minutes after each watering. 2. The substrate improvement plan is to prepare a mixed substrate of perlite + alderite soil + volcanic rock in a ratio of 5:3:2, and 10% decomposed pine needles are added every quarter when loosening the soil. Keep the pH value within the range of 6.0-6.8 through a professional soil detector, and control the EC value within the range of 0.8-1.2mS/cm. 3. The environmental control system is equipped with circulating fans to maintain air circulation, and a temperature and humidity meter is installed for real-time monitoring. It is recommended to maintain ambient humidity of 40-60% and a gradient change of 25-28℃ during the day/18-20℃ at night. Turn on the dehumidifier during the rainy season to prevent the substrate from getting moist. 2. Special maintenance points for green verdant unicorn 1. The scientific fertilization strategy selects a special slow-release fertilizer for meat and applies it at 1/2 of the specified dose. Apply once every year from March to April and September to October, combined with foliar spraying of 2000-fold diluted alginate solution. Be careful to avoid direct light within 48 hours after fertilization. 2. Root inspection process Conduct a root health inspection every six months: gently tap the wall of the pot to remove the plants, and use a soft brush to clean up the old soil. When brown fibrous roots are found, they are immediately trimmed with disinfectant scissors, apply sulfur powder to the incision, and then air the roots for 48 hours, replace them with new soil and place them in a basin.
Through systematic maintenance and management, the risk of green qilin root rot can be significantly reduced. It is recommended to establish a planting log to record each watering, fertilization and environmental parameters, and adjust the maintenance plan in a timely manner based on the growth status of the plants. Regularly use a magnifying glass to check the opening and closing of leaf stomata, which is an effective indicator for judging root health.
