In recent years, it has been widely said that people no longer give red roses on Valentine's Day, and it has become popular to give Phalaenopsis instead. This is because their petals are brightly colored, and some varieties have a double-petal effect. Their layered flower shape is more dazzling than a diamond ring. Most importantly, their flowering period can last for almost half a year without withering!
How to tell if a Phalaenopsis is well-cared for? The most intuitive way is to check its leaves. So, how to take care of it by observing the leaves?
If the leaf pigment is dark green, it means that there is no problem with the plant's appearance, but it just doesn't bloom. Most likely, there is not enough light. Moving it to a place with scattered light in time can alleviate this.
If the leaves are dull and eventually wither, and the roots are still growing well after inspection, it can be basically determined that the plant is short of water. If the roots are not healthy, you should repot it immediately.
If the leaves turn yellow gradually, it may be due to too much light or insufficient nitrogen fertilizer. If there are obvious water-like spots on the leaves, it is generally a bacterial infection. You need to repot the plant and treat it with a fungicide.
If the leaves turn black and become brown, and the roots wither, it is most likely salt damage caused by too much fertilizer. It is recommended to check the fertilizer and wash the medium at least once a month. At the same time, let the plant dry out a bit before watering it again, and never fertilize it again.
If there are black stripes on the leaves, it is mostly caused by viruses.
If the new leaves of the orchid grow fast but feel soft to the touch, it means there is too much nitrogen fertilizer and the growth is hindered, so it cannot grow upward. Increase the light intensity and do not place it in a place with too high a temperature.
If the leaves are wrinkled, it means that the water absorption is insufficient, and the most likely reason is root rot.
If the back of the leaves is dark red, the cause may be too much light, insufficient nitrogen or phosphorus fertilizer. If the bottom leaves of the orchid turn colorless, it is generally time to repot it.
If the old leaves age after the new leaves grow, it is normal. Most of the reasons are related to inappropriate temperature and humidity, insufficient watering, and lack of phosphorus fertilizer.
