Growing Phi Diep yellow orchid we also need to pay special attention to the problem of care because it will determine the ability of the plant to grow and develop.
About watering: We need to water the plant twice a day and let sunbathe in the summer. During the autumn and early winter, we only need to water and reduce the water once a day because then the tree has stopped growing so that the tree does not shrink. By mid-winter, watering will be stopped completely. In case the humidity is too low, we should only mist 1 to 2 times a month.

Regarding fertilization: From February to September, we should only fertilize NPK at the rate of 15-15-15 because Phi Diep Vang does not like fertilizers containing much nitrogen. But from September to November, fertilize with fertilizer at the rate of 10-30-10. The rest from December to the end of January will not fertilize. If we continue to fertilize, Vang Phi Diep will grow and produce seedlings without buds and flowers.

About disease prevention: To prevent the disease for Phi Diep orchids, we spray lime water in the plant. How to mix as follows: Put 1 piece of lime about the size of a thumb in 1.5 liters of water, then wait for the lime to dissolve, then take the clear water to spray on the substrate, done 2 times in 1 month. The clear lime water works to make the plant more sturdy and helps the tree not to rot because in the composition of calcium there is calcium. Besides, lime also helps kill bacteria without harming the body. However, it should be noted that after spraying with lime water for 2 hours, the plants must be sprayed with white water.
