What is the reason why green radish leaves are yellow?
As the popular king of indoor green plants, the yellowing of green radish leaves has troubled many plant lovers. This article will systematically analyze the causes of yellow leaves through four core maintenance points and provide scientific solutions to help you quickly restore the green radish to its bright and green state. In-depth analysis of the four major causes of yellow leaves of green radish caused by imbalance of light, which leads to yellow leaves and green radish's native tropical rainforest environment, making it form semi-shade-loving characteristics. Experimental data shows that when the light intensity exceeds 15000lux, burns will appear on the leaves within 48 hours. It is recommended to use the "three-finger test method": reach out over the plant at noon, and block the light if the shadow is clearly visible. East-facing window sill + gauze curtain with 30% light-blocking rate is the best combination, which can accept 2 hours of direct morning light in winter. The "dipping basin + spraying" combined water replenishment method has the best effect at key points of water management. When the surface soil is 2 cm dry, immerse the entire basin in water until no bubbles are generated, and use leaf spray in the morning and evening (2 drops of white vinegar need to be added to prevent scale). Special note: The water temperature needs to be consistent with room temperature. The temperature difference exceeding 3℃ will trigger root stress. The scientific plan for nutrient supply recommends the use of special liquid fertilizer with N-P-K=3-1-2, applied once every 14 days during the growth period, combined with iron chelated foliar fertilizer once a month. Key skills: Control water 24 hours before fertilization to keep the plants in a state of slight water shortage to increase nutrient absorption. During the winter fertilization stop, you can use banana peel soak solution to wipe the leaves to replenish potassium. Temperature control and fine maintenance establish a "18±3℃ golden temperature zone" and use intelligent temperature and humidity meters to monitor in real time. There are three major measures for protection in winter: ① The thermal insulation cotton sleeve of the basin cover ② The bottom of the basin is padded with a height of 3cm to isolate the cold ground ③ Remove the window when opening the window for ventilation at noon. Pay special attention to avoid direct air conditioning blowing. Wind speeds exceeding 1.5m/s per hour will cause dehydration of the blade edges.
By systematically implementing the above maintenance plan, new healthy leaves can usually be seen in 2-3 weeks. Regular cleaning of leaf surfaces with a soft cloth and monthly root inspection can effectively prevent the recurrence of yellow leaves. Remember that green radish yellow leaves are a warning sign for growth. If you adjust the maintenance methods in time, your green plants will surely regain their vitality.
