What to do when Phalaenopsis leaves turn yellow and soft? Here comes the correct way to handle it

Phalaenopsis is also known as the “Queen of Orchids”, and its blooms look like dancing butterflies, making it deeply loved by people. Although Phalaenopsis is a flower variety grown mainly for its blooms, problems with its leaves should not be underestimated either. If the leaves are unhealthy, it means the plant is unhealthy, and this will also affect blooming. Below, Qinong Web will introduce what to do when Phalaenopsis leaves turn yellow and soft.

When growing Phalaenopsis at home, yellowing and softening leaves often occur. There are many reasons for this, so the measures we take will also differ. Let us take a closer look below at what causes Phalaenopsis leaves to turn yellow and soft.

1. Temperature

As introduced above, Phalaenopsis is honored as the “Queen of Orchids”, so naturally its requirements for the growing environment are also relatively strict. The optimal temperature for Phalaenopsis growth is 18-28℃, and it is not tolerant of high temperatures or severe cold. Temperatures above 32℃ and below 15℃ will both affect the growth of Phalaenopsis. Therefore, extra attention should be paid in summer and winter to ensure it grows in a suitable environment.

2. Water and fertilizer

Phalaenopsis is native to tropical regions and likes environments with relatively high humidity, but if potted plants are watered too much, it easily leads to water accumulation, which in turn causes root rot. So how should we water it?

When Phalaenopsis leaves turn yellow and soft, when watering, you can choose to place the entire pot of Phalaenopsis into a large container filled with water, with the water level at 2/3 of the Phalaenopsis flower pot. It is enough to feel with your hand that the soil is moist.

Phalaenopsis needs fertilizer during its growing period. Usually, we can apply more potassium fertilizer, which will make Phalaenopsis bloom better.

3. Light

Phalaenopsis likes semi-shaded environments and prefers scattered light. Strong light or being placed in a dark environment for a long time will both affect the photosynthesis of Phalaenopsis, causing the leaf surface to turn yellow and soft.

Usually, when we grow Phalaenopsis at home, we place it on a balcony or other place where it can receive direct sunlight. This placement is fine in winter when the light is not strong, but in summer it needs shading to avoid strong sunlight exposure. Normally, sufficient light should also be ensured.

4. Pests and diseases

Common pests of Phalaenopsis include red spiders, scale insects, and others. These two pests can also cause Phalaenopsis leaves to turn yellow and soft. During the process of growing Phalaenopsis, we should usually ensure air circulation, promptly clean up dead branches and rotten leaves, observe the plant's surrounding environment more often, and ensure clean growing conditions. When pests first appear and are still few, you can use a soft-bristled brush to gently wipe the insects off the leaf surface, or you can spray pesticide to remove the pests.

The above is what Qinong Web has introduced for everyone regarding the causes of Phalaenopsis leaves turning yellow and soft and the corresponding handling methods. We hope it can bring you some help. In fact, everyone can also see from this article that the main reason Phalaenopsis leaves turn yellow and soft is still that we growers do not understand the growth habits of Phalaenopsis. Therefore, before growing it, we must do enough preparation so that we can reduce the problems we encounter during the growing process.
