How to care for Imperial Yellow
As a rare ornamental plant, Imperial Yellow is favored by gardening enthusiasts for its unique yellow-green flowers. However, many beginners often encounter problems such as poor flowering and yellowing of branches and leaves during maintenance. This article will systematically analyze the growth habits and maintenance points of Imperial Yellow, helping you easily master cultivation techniques.
Adjusting the Growing Environment of Imperial Yellow
Temperature and Light Management
The optimal growth temperature for Imperial Yellow is between 20-30°C, and it needs to maintain an environment above 12°C in winter. Experimental data shows that when the temperature is below 8°C for more than 72 hours, the plant frostbite rate can reach 80%. It is recommended to transplant outdoors from May, ensuring at least 8 hours of direct sunlight per day, as insufficient light can increase the bud drop rate by 45%.
Accurate Water and Fertilizer Control
During the growing period, keep the soil moist but not waterlogged, and it is recommended to water once in the morning and once in the evening during the high-temperature summer period. Use liquid fertilizer with an EC value of 0.8-1.2mS/cm, applied once every 7-10 days. During the winter dormancy period, reduce the watering amount by 50% to prevent root rot caused by low temperature and high humidity.
Propagation and Cultivation Techniques for Imperial Yellow
Key Points for Cutting Operations
How to care for Imperial Yellow
Select semi-woody branches for cutting, retain 3-4 buds on the cuttings, use a matrix of perlite:vermiculite in a ratio of 3:1, and combine with 800ppm indole butyric acid treatment, which can increase the rooting rate to 90%. Maintain a matrix temperature of 18-21°C and humidity of 75%-85%, and new roots can be seen in about 20 days.
Shaping and Pruning Art
Prune heavily in early spring, retaining 2-3 buds at the base, and combine with pinching to promote lateral branching. Prune the spent flowers promptly after flowering to retain nutrients and promote secondary flowering. By牵引塑形 (牵引塑形 seems to be a typo, assuming it means "training and shaping"), various landscape shapes like umbrella and pagoda can be created to enhance ornamental value.
