The pruning time for butterfly orchids is generally in spring and autumn, which are the peak growing seasons. Spring pruning should be done when the temperature is stable above 15℃, while autumn pruning should be done when the temperature drops below 20℃.
Pruning Tools1. Remove withered and yellow leaves: Observe the leaves of the butterfly orchid and completely remove any withered or diseased leaves. The cut should be close to where the petiole connects to the leaf, ensuring a smooth cut to prevent leaf rot.
2. Remove spent flowers: For flowers that have withered, they should be cut off. The cut should be at the point where the flower stalk connects to the leaf, which can prevent the spent flowers from consuming nutrients.
3. Remove weak and diseased branches: During pruning, if weak and diseased branches are found, they should be removed. The cut should be at the point where the branch connects to the main stem to prevent the spread of pathogens.
4. Remove overly long branches: For excessively long branches, they should be pruned appropriately to promote balanced growth of the plant.
Post-Pruning Care1. Spray fungicide: After pruning, spray the plant with fungicide to prevent the invasion of pathogens.
2. Apply fertilizer appropriately: After pruning, a moderate amount of compound fertilizer can be applied to provide ample nutrition for the butterfly orchid.
3. Maintain ventilation: After pruning, ensure good ventilation around the plant, which is conducive to the plant's recovery and growth.
The pruning method of butterfly orchids may seem simple, but it contains rich knowledge of care. Mastering the correct pruning skills can make butterfly orchids bloom more beautifully. I hope this article can provide help for plant enthusiasts to care for beautiful butterfly orchids.
