What to do if the leaves of the Yulan plant turn yellow
About the knowledge of what to do if the leaves of the Yulan plant turn yellow, and the methods to improve the yellowing of orchid leaves, let's follow the editor to find out together!
1. Trim yellow leaves: Solution: If the number of yellow leaves on the orchid is small and the area is small, you can first avoid trimming and strengthen maintenance management, waiting for the leaves to slowly turn green. If the number of yellow leaves is large and the area is extensive, and there are symptoms such as drying, drooping, and withering, it may be due to infection with bacteria. You need to trim the leaves and petioles together after disinfecting the scissors, burn the trimmed leaves, and spray the plant with carbendazim for disinfection and sterilization.
2. Light management: Yellowing of orchid leaves may also be caused by improper lighting. When the plant is exposed to strong direct sunlight, the leaves may be scorched and turn yellow, or if the orchid is kept in a dim environment for a long time, the leaves lack light to synthesize chlorophyll, causing the leaves to fade and turn yellow. Solution: After trimming the yellow leaves, place the plant in a well-lit indoor area, and move it outside to receive sunlight when the light is weak.
3. Proper watering: When the orchid requires a large amount of water, insufficient watering can easily cause the plant to dehydrate. Dehydrated leaves not only turn yellow but may also wither. Solution: Water promptly, following the "water when dry and stop when wet" principle. Water the plant when the top layer of soil is dry, and stop when water seeps out from the bottom of the pot.
4. Root pruning and replanting: Excessive watering and over-fertilization can damage the roots, leading to root rot. Rotting roots cannot supply enough water and nutrients to the leaves, causing the leaves to lack water and nutrients and turn yellow. Solution: You need to dig the roots out of the soil, trim away the rotting, withered, and dense roots, apply carbendazim to the wounds for disinfection, then place them in a well-ventilated area to dry until the wounds contract. After the wounds contract, change the soil and replant.
