1. Crab claw orchid is a short-day plant, but it needs sufficient sunshine during its growing period. It is easy to form flower buds under the illumination of 8~ 10h every day, and it can bloom in 2~3 months. If you don't receive sunlight, the buds that have already grown will also fall off, resulting in little or no flowering.

2. Watering: After the crab claw orchid is grafted, put it in a cool, rain-proof and ventilated place for about 30 days. Don't move it casually. Don't be too dry in the basin. When watering, be careful not to get water on the joints, but to water them from below. In rainy days, it should be placed in a shelter to avoid joint rot. After 30 days, if the surface of the scion is green and shiny, it means that it has survived. If the scion is wilted and dull, it is necessary to check whether the grafting interface is rotten, so that it can be grafted again in time.

3. Fertilization: apply dilute liquid fertilizer 1 time every half month in spring, and dilute it with 3 parts of decomposed cake fertilizer and 7 parts of water. From autumn to flowering, it is necessary to increase the amount of fertilization and watering to facilitate the formation of flower buds. Try to avoid contact with the joint when fertilizing, so as not to damage the stem with fertilizer. After flowering, it will sleep for 5~6 weeks, so it is necessary to control watering, stop fertilization, cut off all residual flowers and trim them. After the dormancy period, when new buds grow at the top of abnormal stems, normal fertilizer and water management will be carried out.

4. Pest control: Crab claw orchids are vulnerable to red spiders in poorly ventilated environment, resulting in withered stems and reduced ornamental value. If you find red spider, you should immediately spray 3000 times of diflubenzuron No.3 solution every 7~ 10d 1 time.
