How to Deal with Yellowing Leaves of Orchid Grass
Let me tell you how to handle yellowing leaves of orchid grass and introduce some related information about green plants and flowers that teach you how to solve yellow leaves. Next, the editor will explain.
Orchids are traditional famous flowers in China, and many people will grow one or several orchids at home. During the cultivation process, the leaves of orchids may turn yellow, which may be caused by bacterial infections, improper lighting, improper watering, and excessive fertilization. It is necessary to prune the yellow leaves and manage lighting and water appropriately. If excessive watering and thick fertilization cause root rot, leading to yellowing leaves, root pruning and replanting in new soil are also required.
1. Pruning Yellow Leaves
When the yellowing of orchid leaves is minimal and the area is small, you can skip pruning and focus on strengthening maintenance, waiting for the leaves to gradually turn green. If there are many yellow leaves over a large area, accompanied by dryness, drooping, and wilted conditions, it might be due to a bacterial infection. In this case, you should消毒 the scissors and剪 off the leaves along with the petioles, then burn them 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 get sunburned and turn yellow. Alternatively, if the orchid is kept in a dim environment for an extended period, the leaves lack light for chlorophyll synthesis and may fade and turn yellow. The treatment method is to prune the yellow leaves and place the plant in an indoor area with plenty of scattered light, or move it outdoors to receive sunlight when light is weak.
3. Appropriate Watering
When orchids require a lot of water, insufficient watering can easily cause the plant to dehydrate. Dehydrated plants not only have yellow leaves but may also wilt. It is necessary to water promptly, following the "water when dry and stop when wet" principle. Water when the topsoil is dry, and stop when water seeps out from the bottom of the pot.
4. Root Pruning and Replanting
Excessive watering and thick fertilization can damage the roots, leading to root rot. Rotten roots cannot transport enough water and nutrients to the leaves, causing the leaves to lack water and nutrients and turn yellow. You need to dig the roots out of the soil, prune away the rotten, 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 have contracted, replant in new soil.
The above sharing on how to deal with yellowing leaves of orchid grass and how to solve the problem of yellow leaves is for everyone to learn and understand!
