A bit of knowledge to share with you about whether to trim the tips of orchid leaves and related introductions on orchid leaf tip pruning and prevention methods for green plants and flowers. Next, the editor will provide an introduction.
I. Trimming is Necessary
1. Reasons
Factors that cause the tips of orchid leaves to turn brown include low humidity, unstable environment, and air pollution, as well as inappropriate cultivation practices such as excessive sun exposure, long-term lack of sunlight, waterlogging, drought, fertilizer damage, and excessive concentration of medication. Diseases such as brown spot, anthracnose, black spot, leaf blight, and tip blight can also cause leaf tip browning.
2. Trimming Methods
It is necessary to trim the brown parts of the leaves with browning tips promptly, cutting 1 cm away from the brown part. There are three methods of trimming: straight cut, diagonal cut at a 45-degree angle, and trimming along the edge of the brown tip.
For leaves with browning tips caused by diseases, trimming should be done according to the condition of the browning. If not only the tip is brown but also many spots appear on the leaf, the leaf should be cut from the base, followed by the application of fungicides like methyl thiophanate solution.
3. Post-Trimming Care
For fungal browning tips, it is not advisable to spray water after trimming, as water can carry and spread pathogens, worsening the condition. If water is to be sprayed, it should be done after the water on the leaves has evaporated, followed by a spray of diluted fungicides.
II. Prevention Methods for Orchid Leaf Tip Browning
1. Environmental and Improper Care Factors
For leaf tip browning caused by unsuitable environments and improper care, attention should be paid to maintaining a suitable care environment, with stable temperature, humidity, soil, and light.

2. Disease Factors
For leaf tip browning caused by diseases, preventive measures should be taken in advance. The diseases that cause leaf tip browning in orchids are mainly caused by bacterial and fungal infections. Preventive measures can include the use of fungicides in early spring, such as agricultural streptomycin, Jieguoning, and Keshade to kill bacteria, and methyl thiophanate, 百菌清 (bacterial blight) to kill fungi, with applications every 10 to 15 days.
