What Causes the Tips of Orchid Leaves to Turn Yellow
A comprehensive introduction to why the tips of orchid leaves turn yellow and tips on solving yellowing leaves, the details are as follows:
Orchids, also known as spring orchids, grass orchids, fragrant ancestors, and quiet orchids, belong to the orchid family. Orchids prefer overcast days and humid environments, are not drought-resistant, and are afraid of direct strong sunlight. It is best to use fertile soil and place them in a well-ventilated area when caring for orchids, as this will help them grow better. Orchids are loved by many for their simple and elegant symbolism. When caring for orchids, it is common to encounter yellowing of the leaf tips, and the specific reasons are as follows.
1. Water
When orchids have not been watered for too long, the leaves lack water and will turn yellow. If this continues for too long, it can even lead to the death of the entire plant. At the same time, excessive watering can cause water to accumulate at the bottom, preventing the roots from breathing, and root rot can also cause the tips of the leaves to turn yellow. Therefore, it is sufficient to keep the soil slightly moist when watering, ensuring enough water for the growth of orchids, and also to ventilate appropriately.
2. Temperature
The suitable temperature for orchid growth is 18-30 degrees Celsius. Temperatures above 30 degrees Celsius can cause the leaves to turn yellow; temperatures below 0 degrees Celsius can cause frost damage, which can also lead to yellowing leaves. Therefore, when caring for orchids, especially in winter, it is important to keep them warm.
3. Fertilizing
When orchids have not been fertilized for a long time or the fertilizer concentration is too low, the young leaves will turn yellow first, and more fertilization is needed at this time. However, excessive fertilizing can lead to soil compaction, and overly concentrated fertilizer can cause root burn, leading to yellowing of the leaf tips.
4. Diseases and Pests
During periods of high temperatures and heavy rain, microorganisms and bacteria multiply, leading to diseases such as anthracnose. After being affected by diseases and pests, the orchid leaves will turn yellow entirely. If yellowing of the leaf tips is caused by diseases and pests, you can spray some Bordeaux mixture or other pesticides to solve this issue.
