How to grow doubanlan

1. Maintenance methods

1. Temperature: Fifteen to twenty-eight degrees is the most suitable range. In an environment above thirty-five degrees, its growth rate will be very slow or even stagnant. When the temperature is below ten degrees, you may get frozen. Therefore, under these two extreme conditions, we need to pay attention to adjustments.

2. Light: The bean orchid has high requirements for sunlight. In too dark conditions, its flowering will be severely affected. Generally speaking, no shade is needed in winter and spring. In summer and autumn when the sunlight is strong, shade is needed.

3. Watering: The bean orchid likes moisture, but its waterlogging resistance is not very good. In the summer, try to moisten the pots every two days and water them thoroughly twice a month. The steps in spring and autumn are basically the same, usually the pots are moistened twice a week and watered thoroughly once a month. Water needs to be controlled in winter, and the pots should generally be moistened once a week.

4. Fertilization: It does not require much fertilizer. Choose soil rich in nutrients and add sufficient fertilizer when planting and repotting, and there is basically no need for top dressing. Too much fat can actually cause harm.

2. Breeding techniques

1. Reproduction: It can be propagated by division. Before breeding, water needs to be controlled for a period of time. Then comes the specific steps of division. When dividing, make sure that each part must have several pseudobulbs. Then prepare sandy soil as the substrate. After planting, water them thoroughly and place them in a cool place.

2. Repotting: The quality of the soil of the bean orchid is still relatively high, so it is best to change the soil regularly, preferably once a year. In this way, we can ensure that there are sufficient nutrients in the soil and avoid serious soil caking. However, when repotting, be careful to trim the roots and leaves slightly, but don't damage the taproot.

3. Problem diagnosis and treatment

1. Diseases: Some diseases occur more frequently in summer and autumn, such as "anthracnose", "leaf spot" and so on. In addition to cutting off the infected leaves and treating them properly, it is best to use some pesticides so that recovery speeds up.

2. Pests: Mainly "aphids", "red spiders" and the like. Generally, various pesticides are effective and easy to prevent and control.
