Let me share with you some small experiences on how to care for蟹爪lan optimally and the temperature requirements for蟹爪lan flowering, the specific details are as follows:
It's already the season for蟹爪lan to bloom. The optimal temperature for蟹爪lan to bloom is around 15 to 20 degrees, with a bit of temperature difference to help the plant produce flower buds. We all know that蟹爪lan is a short-day flowering plant, which only blooms when days are short and nights are long. With 8 hours of sunlight a day and a reasonable temperature, it will bloom soon.
Every year, some gardening enthusiasts report the problem of蟹爪lan dropping flower buds. What causes this issue?
1. Cultivation
蟹爪lan is very sensitive to the environment. Some enthusiasts, after purchasing蟹爪lan, eagerly repot it. The newly bought蟹爪lan comes with flower buds, and repotting can damage its root system, disrupting its normal growth rhythm.蟹爪lan's first reaction is to survive, so it abandons the development of offspring, causing the flower buds to fall off, as flowering is essential for its propagation.
So, don't rush to repot the newly bought蟹爪lan. You can use the method of simulated planting, keeping it in the original pot and planting it in a nice-looking pot first. After it finishes blooming, you can repot it again. This way, it does not affect the appearance or blooming.
2. Light
Whether蟹爪lan is producing flower buds or blooming, it needs some light. Many enthusiasts place蟹爪lan directly in the living room or other environments without light for easy viewing. In such an environment,蟹爪lan is prone to dropping flower buds. At the very least, it should be placed in a place with diffused light to prevent flower bud drop.
3. Temperature
The suitable temperature range for蟹爪lan growth is between 15-25 degrees, which is also the optimal temperature for flowering and producing flower buds. The low temperature should not exceed 10 degrees, and the high temperature should not exceed 20 degrees. This way,蟹爪lan will not drop flower buds, as too cold or too hot will affect its flowering.
4. Watering
Although蟹爪lan prefers a humid environment, it is an epiphytic plant and requires good ventilation in the roots. Planting in a pot can affect root respiration, and excessive watering can cause root rot. Excessive watering during the blooming period can also affect flowering, as during the blooming period, the plant is also suitable for growth. Excessive water can lead to the absorption of too much nitrogen fertilizer, causing the plant to focus on vegetative growth and resulting in flower bud drop. The principle of watering is to water thoroughly when the potting soil is completely dry.
5. Fertilizing
When蟹爪lan is producing flower buds, you can use a fertilizer high in phosphorus and potassium, such as monopotassium phosphate. It can be diluted with water and used for root irrigation or foliar application. Using it once a week can effectively promote the differentiation of flower buds in蟹爪lan. Do not fertilize during the blooming period.
6. Extending the blooming period
Crab claw orchids are beautiful when in bloom, but as the saying goes, 'Good flowers do not bloom often.' They bloom only a few times a year, and the flower buds fade after a few days. To extend the blooming period of蟹爪lan, you can place it in a cooler environment, as lower temperatures reduce its metabolism and extend the blooming period. Lighting should also be adjusted. To extend the blooming period of蟹爪lan, the light should not be too abundant, with diffused light being the most reasonable. By following this method, the blooming time of蟹爪lan flowers can be extended at least twice.
