An introduction to the knowledge of why the buds of蟹爪兰 (Cattleya orchid) fall off, with detailed explanations provided below
Reasons for the Bud Drop of蟹爪兰 (Cattleya orchid)
The flowering period of蟹爪兰 (Cattleya orchid) begins in the late autumn and early winter and continues until the following spring. However, if the buds keep falling off just as they are about to bloom, one should check whether it is due to a dark and insufficiently lit environment, improper application of fertilizer and water, lack of thinning and pruning, or a drop in climatic conditions.
During the flowering period,蟹爪兰 (Cattleya orchid) requires ample light for nourishment. Even though the flowering period includes winter, insufficient lighting should not be a reason for the bud drop. Cultivators must ensure adequate daily light, and if necessary, use artificial lighting methods to allow the flowers to bloom normally.
If a large number of buds fall off, one should consider whether watering and fertilizing have not been done properly. Excessive application of nitrogenous fertilizer, which supplies nutrients mainly to the leaves, can cause the buds to lack nutrition and fall off. Over-frequent watering prevents the potting soil from drying out and becoming moist, and an overly wet growing environment can lead to the buds lacking the ability to adhere to the stem, causing them to fall off.
Pruning and thinning of the buds should start from mid-to-late October, which is also when the flowering period begins. Often, 2 to 3 buds grow on a single stem. If they are too dense, not only does the growing space decrease, but they can also compete with each other for nutrients, causing the buds to wither. It is sufficient to leave a single bud on a single branch, keeping the largest and healthiest one.
Compared to the growing season, the temperature drops more quickly during the flowering season, especially in the coldest months of winter, when the temperature can drop below freezing. The best flowering temperature is between 15 to 22°C, with a minimum of 10°C. An environment below 10°C can easily cause蟹爪兰 (Cattleya orchid) to have withered buds and cause them to fall off.
