How to grow black orchid

1. Breeding environment

1. Soil: Mo Lan likes a humid soil environment. It is best to choose an acidic soil that is not sticky and has good air permeability, which can allow its roots to grow better.

2. Light: It needs to receive appropriate sunlight, but in the summer, it is necessary to take good shade measures, otherwise the leaves will turn yellow or even stop growing. It is best to expose it to diffuse light, but not too strong sunlight. In winter, you should increase the sunlight appropriately, but pay attention to the temperature to avoid frostbite.

3. Fertilization: It does not have strict requirements on fertilizers and it can grow normally even without fertilizer. You can choose to apply thin liquid fertilizer to it in spring and autumn every year. When it enters the dormant period, you don’t need to continue fertilizing.

4. Temperature: Under normal circumstances, the temperature should be controlled at 20-28℃. If it is below 20℃, the growth will become slow, and if it is above 30℃, it will go dormant. In winter, the temperature should be controlled at 10-16℃ during the day and 5-10℃ at night.

2. Breeding Methods

1. Propagation by division: prepare the flower pots, choose loose and fertile sandy soil, water in small amounts before division, choose relatively sturdy stems, and you can use 5 connected pseudobulbs, cut them off and plant them in new soil. In order to ensure the moisture of the soil, water it thoroughly after division, and it will survive in about half a month.

2. Tissue culture propagation: Insert the new shoots of Mo Lan into a container filled with nutrient solution, and then fix it. It will grow roots in about a week, and then it can be moved to water for cultivation.

3. Common pests and diseases

1. White rot: It is more likely to occur in a relatively humid environment. Clean the infected soil in time, remove the plant from the pot and check for rot, remove the rotten part and disinfect it.

2. Black spot disease: It often occurs in hot and rainy seasons. If you find black-brown spots on the leaves, remove them in time and increase ventilation.
