Reasons for the splitting of Phalaenopsis leaves
Let's share some knowledge about the orchid plant Phalaenopsis, specifically the reasons for the splitting of its leaves, as follows:
Many orchid enthusiasts encounter the issue of Phalaenopsis leaves splitting, often from the center, especially in northern regions where this is more common. Firstly, leaf splitting does not cause fatal harm to the plant. The main reason for the splitting is the dryness of the air, so it is important to try to increase humidity.
Newly purchased Phalaenopsis orchids tend to have a higher incidence of leaf splitting, as these plants are usually grown in greenhouse environments with high humidity and rapid growth, resulting in fragile and tender leaves. A slight inward bend of the leaf can cause it to split. However, orchid enthusiasts need not worry; as long as it is kept dry, the plant will heal itself by forming a scar.
Why is the condition of newly purchased Phalaenopsis orchids poor?
When we bring a Phalaenopsis orchid into our home, the last environment it left is a greenhouse, a uniformly warm and humid environment, and most importantly, one that maintains the ideal lighting for Phalaenopsis. Once at home, the humidity drops, and lighting becomes inconsistent, which means the plant needs an adaptation period to adjust to the new environment (its physiology will change to cope with the new conditions). This adaptation period will result in some phenomena:
1. Leaves become weak; 2. Leaves stop growing; 3. New leaves are smaller than the original ones; 4. Root dryness is observed.
During this period, it is necessary to gradually help the plant recover in the shortest time possible with proper watering and lighting. It is recommended not to fertilize until the plant has recovered. Additionally, I have a piece of advice: I never use spraying to create humidity. The reason is that after the water is sprayed, the humidity is high for a few hours, but once the water dries, the humidity drops rapidly, and the orchid may not know which humidity level to adapt to. Moreover, prolonged leaf moisture accumulation is a big no-no, as soft rot, bacterial diseases, and other pathogens thrive in such conditions.
The above is a detailed explanation of the reasons for the splitting of Phalaenopsis leaves. I hope it can be of help to you!
