Tips for judging yellow leaves: Dark yellow leaves and no light, shrinking new buds are mostly caused by stagnant water and rotten roots; scorched leaf margins and curling indicate lack of water. It is recommended to use flower pots with drainage holes and lay ceramite on the bottom of the basin to enhance breathability. Law of Balancing Light Demand Green radish likes to scatter light in an environment and is recommended to place it 1-2 meters away from the east/north facing windows. When the light is too strong, use gauze curtains to filter the light, and when the light is insufficient, rotate the position every 15 days. Special treatment: In late spring and early summer, you can accept direct weak light in the morning for 1 hour to promote chlorophyll synthesis. Pay attention to the changes of leaf spots, and adjust the position immediately if sunburn spots appear. Scientific solution for nutrition supply causes and solutions to yellowing of green radish leaves
During the growth period (April to September), nitrogen, phosphorus and potassium balanced liquid fertilizer (diluted 1500 times) is applied every half month, and fertilizer is stopped in winter.

Green radish yellow leaf repair strategy four-step emergency response 1. Disinfection scissors cut off leaves with yellowing rate>60%. Check the roots: prune the black roots and rot. 3. Soak the roots in 1000 times carbendazim solution for 20 minutes 4. Switch to a new substrate (peat: perlite =3:1). Advanced maintenance skills. The best operating period is spring early morning, and control the water 3 days in advance to make the branches flexible. Operating points: Keep the air roots of the main stem, keep a 45° angle when winding, and the new buds at the top face out. After reorganization, use diluted beer (1:50) to wipe the leaves to promote photosynthesis. The systematic pruning and rejuvenation method adopts an alternate pruning strategy: the first phase will cut off the old branches of 20cm on the south side, and treat the branches on the north side after the new buds germinate. Focus on retaining the bud points of the internodes, and the incision is 0.5 cm away from the node and forms a 45° oblique angle. Brassinolide (0.01mg/L) was applied after pruning to promote lateral bud differentiation.
By regularly observing the condition of leaves, establishing maintenance logs, and mastering environmental data (it is recommended to equip a temperature and humidity meter), the maintenance level of green radish can be systematically improved. Remember to "three points of maintenance and seven points of prevention", establish a quarterly maintenance calendar, and regularly loosen the soil and replace the pots, so that the green radish can continue to maintain its emerald luster.
