What if the leaves of the orchid turn yellow?

1. Scientific watering

Reason: if you don't water enough for a long time or forget to water, it will make the orchid yellow. In addition, if too much water is irrigated for a long time, a large amount of stagnant water will be produced in the soil, which will soak the roots of the plant, affect the rate of absorption of nutrients, and lead to the lack of nutrients and yellowing of some leaves.

Solution: water the orchid scientifically, do not water the soil when the soil is still wet, wait until the soil is dry and then start watering, not too much water at a time. If you water less at ordinary times, pour more water to help it recover. If you pour more water at ordinary times, you will raise the bottom of the flowerpot and let the water evaporate quickly.

2. Science receives light.

Reason: because the hanging orchid is more attractive, so he can not be exposed to strong light for a long time, otherwise his leaves are likely to be sunburned, resulting in macula. In addition, although it likes shade, it can not lose any light, otherwise its photosynthesis will not proceed normally, and the speed of synthesizing chlorophyll will slow down, thus making the leaves look yellow.

Solution: let the hanging orchid receive light scientifically. Appropriate shade when the light is too strong in summer, and move it to the south balcony when the light is insufficient in winter. If you are sunburned by strong light, put it in a cool place to take care of it slowly, if there is no light, put it in a place where the sun is bright.

3. Scientific fertilizer

Reason: if you do not fertilize the orchid for a long time, the orchid will turn yellow due to lack of nutrients. In addition, if you fertilize the orchid too much, there is no way to absorb so much fertilizer, the excess fertilizer will remain in the soil to cause damage to the root system of the plant, causing leaves to yellowing.

Solution: fertilize the orchid scientifically, neither too much nor too little. If you apply too little fertilizer, you should apply some fertilizer for it. If you apply too much fertilizer, you should wash away the excess fertilizer with clean water.
