What to do when orchid leaves turn brown at the tips in summer
If the browning of the tips is caused by bacterial or fungal infections, we should use medication to eliminate and prevent it. Use dimethomorph, dissolve one pill in 1000 milliliters of water, and then spray it on the orchid leaves. When spraying, make sure to spray evenly, covering both the front and back of the leaves where possible.
In summer, many orchid enthusiasts will find that the leaves of their orchids have different degrees of browning at the tips. Some leaves still turn brown at the tips even after pruning. The main reasons for the browning of the tips are two.
The first is physiological browning caused by environmental issues. The second is browning caused by bacterial and fungal infections. For browning caused by environmental factors, due to hot and dry weather, we need to frequently spray water mist to increase humidity in the environment, thereby reducing the occurrence of browning.
If the browning of the tips is caused by bacterial or fungal infections, we should use medication to eliminate and prevent it. Use dimethomorph, dissolve one pill in 1000 milliliters of water, and then spray it on the orchid leaves. When spraying, make sure to spray evenly, covering both the front and back of the leaves where possible.
For fungal diseases such as powdery mildew and grey mold, which are common on leaves, dimethomorph has a good eradication effect. It is a complex of tebuconazole and pyraclostrobin, a fungicide that is low in toxicity, environmentally friendly, odorless, and suitable for home use. It has strong systemic and penetration properties.
It can not only protect orchids from being infected by pathogens but also completely eradicate the disease. Using this method to prevent browning at the tips of orchid leaves is foolproof. Therefore, during this period, we mainly focus on prevention. It is too late to treat the browning after it has occurred. So, the main approach in caring for orchids is prevention.
