What are the reasons for the yellowing of Phalaenopsis leaves?

A small knowledge of experience, introducing the reasons for the yellowing of Phalaenopsis leaves in the aspect of green plants and flowers, let's understand together.

What are the reasons for the yellowing of Phalaenopsis leaves?

Phalaenopsis is not unfamiliar to many flower enthusiasts. It has a rich variety of colors, ranging from pink, pure white to yellow, and deep purple. Due to its high ornamental value, it can be seen in many flower exhibitions around the world, and it is also known as the "Queen of Orchids." So why do Phalaenopsis leaves often turn yellow during cultivation?

Improper watering

Phalaenopsis is a tropical plant that grows better in a humid environment, but it also has another weakness - it fears waterlogging. If the soil of Phalaenopsis accumulates water, it often leads to the rotting of the plant's roots and rhizomes, which usually does not show up in a short time. It only appears when the situation is quite serious, resulting in yellow leaves. This situation often occurs after the rainy season when the pot or soil condition is not observed in time and the pot is not moved to a suitable place. At this time, it is necessary to clean the pot soil promptly, cut off the leaves that have changed, and if the roots are severely decayed, consider re-cultivating the plant.

Improper fertilization

If the yellowing of Phalaenopsis leaves is caused by fertilization, it is usually due to excessive fertilization at once, which burns the roots and rhizomes of Phalaenopsis, causing yellow leaves. Because Phalaenopsis does not require heavy fertilization, it should be fertilized thinly and frequently. When fertilizing Phalaenopsis, it is necessary to apply thin fertilizer skillfully, and avoid applying thick fertilizers, heavy fertilizers, or unripe liquid fertilizers. The next day after fertilization, water the plant with clean water to dilute the fertilizer and prevent fertilizer damage.

Improper lighting

Phalaenopsis prefers scattered light and should not be exposed to direct sunlight. It is best to place it in a shaded corner during summer and near a window sill in winter for photosynthesis. If it is placed in a dark and damp environment for a long time, it is not conducive to the growth of Phalaenopsis and can lead to the softening and yellowing of its leaves.

Inappropriate temperature

As the "Queen of Foreign Orchids," Phalaenopsis has strict requirements for its growing environment. The optimal temperature for Phalaenopsis growth is 18-28°C, and it is not tolerant to high temperatures and severe cold. Temperatures above 32°C and below 15°C will affect the growth of Phalaenopsis. Therefore, special attention should be paid in summer and winter to ensure its growth in a suitable environment.

The above is the related explanation for the reasons for the yellowing of Phalaenopsis leaves, hoping to bring a little help to your life!
