What to Do When Orchid Leaves Curl
Today, I will explain in detail how to deal with curling orchid leaves and share knowledge about improving the condition of curling orchid leaves. Let's dive into the information together.
Orchids, also known as Chinese orchids, spring orchids, orchid grass, fragrant orchids, national fragrance, fragrant ancestors, and fairies of the empty valley, are a general term for orchidaceae orchid plants. During the cultivation of orchids, curling leaves may be caused by excessive light, insufficient light, insufficient watering, insufficient fertilization, overly concentrated fertilization, compacted soil, and root rot. It is necessary to adjust lighting, watering, fertilizing, change the soil, and treat the roots based on different causes.
Methods to improve curling orchid leaves:
1. Appropriate Lighting
Orchids prefer shade and are sensitive to direct sunlight. Excessive light can cause leaves to curl.
Solution: You can use a shading cloth to create a small shelter for shade, or move the orchid to an indoor area with scattered light and good air circulation. When indoor light is weak, place the orchid outside to receive light to prevent insufficient light, plant elongation, and yellowing and curling of the leaves.
2. Appropriate Watering
Orchids prefer moisture and dislike dryness. Insufficient watering can cause the plant to lack water, leading to curling leaves.
Solution: It is necessary to water thoroughly and follow the principle of "watering when dry and stopping when wet." Water when the top layer of soil is slightly dry and white, and stop when water seeps out from the bottom layer of the soil, keeping the soil moist. You can also use a spray bottle to spray water on the leaves to better provide moisture.
3. Appropriate Fertilization
Improper fertilization can cause orchid leaves to curl.
Solution: Orchids are fertilizer-loving plants with a high demand for fertilizer. Insufficient fertilization can cause leaves to curl. Fertilize based on the plant's growth condition, applying a small amount multiple times, thin and frequent fertilization, and applying near the roots. If the fertilizer is too concentrated, water to dilute the fertilizer to prevent plant fertilizer burn and leaf curling.
4. Change Soil
Improper soil can cause orchid leaves to curl.
Solution: Orchids grow best in well-drained, loose, fertile, humus-rich, slightly acidic soil. When the soil becomes compacted or severely alkalized, the plant grows poorly, causing yellowing and curling of the leaves. It is necessary to change the soil. The soil can be mixed with leaf mold, garden soil, river sand, and a small amount of river sand to make a growing medium. Before filling the pot with soil, cover the bottom with a layer of broken tiles to aid drainage.
5. Treat the Roots
Root rot can cause orchid leaves to curl.
Solution: Excessive watering and overly concentrated fertilization can easily cause root rot. When the plant's roots rot, their ability to transport water and nutrients is weakened, causing the leaves to lack moisture and nutrients, leading to yellowing and curling. It is necessary to dig the roots out of the soil, cut off the rotting, withered, and dense roots, apply carbendazim to the wounds for disinfection, let them dry in a ventilated area until the wounds contract, and then replant in new soil.
