How to cut off yellow green radish leaves
As a common leaf-viewing plant in the home, the yellowing of its leaves puzzles many plant lovers. Correct handling of yellow leaves not only maintains the beauty of plants, but is also an important part of maintaining plant health. This article will systematically analyze the yellow leaf treatment plan from pruning skills to maintenance points. Detailed explanation of green radish pruning skills local pruning method When only 1-2 cm yellowing occurs at the leaf tip, it is recommended to use 45° oblique shearing method. Keep the green part of the main leaf surface and trim it along the vein with disinfected gardening scissors. The incision area is controlled within 15% of the total leaf area. This method is suitable for slight yellowing caused by metabolism and can maximize the photosynthesis area. Whole leaf resection When the yellowing area exceeds 1/3 of the leaf, it is necessary to cut flat from the base of the petiole 2 cm. Wipe the scissors with 75% alcohol before operation, and apply carbendazim powder to the incision to prevent infection. Pay attention to preserve the integrity of leaf sheaths and avoid damaging stem vascular bundles. This method is suitable for regional yellow leaves caused by fungal infections or nutritional deficiencies. When continuous yellow leaves appear during pruning, cut obliquely at 2-3 nodes below the lesion. The incision should avoid the growth point of the aerial roots and retain at least one healthy leaf. After pruning, place it in a scattered light environment and cooperate with HB-101 vitin to promote new buds germination. This method is suitable for systemic yellowing caused by root rot or severe frostbite. Key points for prevention and maintenance of yellow leaves: Environmental control factors maintain the growth temperature of 18-28℃, and the air humidity is maintained at 60%-70%. Adopt the watering principle of "see dry, see wet", water thoroughly every 5 days in summer and extend to 10-15 days in winter. Wipe the leaf surfaces with beer diluent (1:50) every month to effectively prevent the leaf margins from being scorched. The nutrient supply plan applies nitrogen, phosphorus and potassium balanced liquid fertilizer (EC value 1.2-1.5mS/cm) every half month during the growth period, and uses potassium dihydrogen phosphate foliar fertilizer in winter. Regularly add chelated iron to prevent iron-deficient yellowing. Add decomposed sheep manure organic fertilizer when changing pots to ensure the continuous fertilizer supply capacity of the substrate.
Through scientific pruning and systematic maintenance, it can not only solve the existing yellow leaf problem, but also improve the stress resistance of green radish from the root cause. It is recommended to establish a maintenance log to record pruning time, environmental parameters and plant reactions, and gradually form a personalized maintenance plan to keep green radish green all year round.
