1、 How to make orchid leaves green

If you want its leaves to turn green, you need enough chlorophyll, and there are two conditions for chlorophyll, one is to have an appropriate amount of nitrogen fertilizer, the other is to have sufficient light, neither of which is lacking. Appropriate amount of fertilizer should be applied in the growing season. Nitrogen fertilizer should be selected as the fertilizer. It should be applied after dilution to promote better absorption of plants. At ordinary times, it should be exposed to scattered light and placed in a place with low light. The light in summer is relatively strong, so it must be blocked and avoided. In addition, pay attention to air humidity. When the climate is dry, spray water frequently to moisturize and improve the air humidity

2、 How to treat the loss of green leaves of orchids

1. Apply fertilizer: if its leaves lose green, it is likely to lack fertilizer, especially nitrogen fertilizer. Nitrogen is the basic material of chlorophyll and is indispensable. Nitrogen fertilizer should be applied as soon as possible. Nitrogen fertilizer can promote its better photosynthesis and produce more chlorophyll, so that the leaves will be darker and greener

2. More sun astigmatism: if you put it in the shade for a long time during maintenance, the plant will not see light, cannot carry out photosynthesis, and will also lose green. It should be moved to the astigmatism and exposed to the sun. But pay attention to avoid strong light. The leaves will turn yellow and dry when exposed to strong light

3. Often spray water: the growth of orchids has certain requirements for humidity. If the environment is too dry, the leaves are easy to turn yellow and lose green. Therefore, when the climate is dry, we should often spray water to moisturize, so that the plants can grow in a high humidity environment, and the leaves will be more dark green
