- Overwatering: This is the most frequent cause. Excess water can lead to root rot, preventing the plant from absorbing nutrients and causing leaves to yellow accordingly.
- Underwatering: Conversely, not providing enough water can also stress the plant, leading to yellowing leaves as the orchid struggles to survive.
- Improper Light Conditions: Orchids thrive in bright indirect light. Too much direct sunlight can scorch leaves, while too little can cause them to turn yellow and drop.
- Nutrient Deficiency: Orchids require specific nutrients, particularly nitrogen. A lack of essential nutrients can result in yellow leaves. If you notice yellowing leaves, especially if they are yellowing around the tips or edges, it may indicate a lack of these nutrients.
- Temperature Stress: Extreme temperature, either too hot or too cold, can stress Orchids, leading to yellowing leaves.
- Pests and Diseases: Insects like aphids or issues like fungal infections can cause discoloration and overall deterioration of the plant’s health.
- Natural Aging: Older leaves will naturally yellow and die off. This is regared as part of the plant’s life cycle, particularly if they are at the base of the plant.
Should You Cut Off Yellow Orchid Leaves?

If the oldest leaves, which are at the base of the plant, are turning yellow naturally as part of the plant’s life cycle, you can leave them on until they dry up and fall off on their own. However, if younger leaves are turning yellow prematurely, it could indicate an issue like overwatering, nutrient deficiency, or disease. In these situations, it is not recommended to remove these orchid's yellow leaves. Instead, you should try to find the reasons behind it and resolve the problem. Focus on providing proper orchid care - bright indirect light, appropriate watering, humidity, and fertilization, since this will further prevent and treat yellow leaves.
