Why do the leaves of Epipremnum aureum turn yellow in summer?
Below is an introduction to the reasons why the leaves of Epipremnum aureum turn yellow in summer, as well as knowledge about yellowing leaves and solutions in the field of green plants and flowers. Let's learn about it together.
Epipremnum aureum is a very beautiful ornamental leafy green plant. It can be hung as a hanging plant or allowed to climb on walls to form a Epipremnum aureum wall. The green leaves are very beautiful. The growing season of Epipremnum aureum is in spring, summer, and autumn. It is not afraid of high temperatures but afraid of low temperatures. Therefore, when we grow it at home during the summer, it is also a season of vigorous growth. Usually, we must ensure that it has sufficient nutrients and water to grow rapidly. However, recently many gardening enthusiasts have said that although it is now summer and the plant is growing, the leaves are still turning yellow. What is the reason for this? Today, Xiaoqi will tell you about two key reasons for yellowing leaves in Epipremnum aureum during summer.
1. Improper lighting
Most people grow Epipremnum aureum indoors. The plant has strict requirements for lighting. If there is insufficient light indoors, the leaves of Epipremnum aureum will become smaller and smaller, and the new leaves will turn yellow. This is one of the main reasons for yellowing leaves. Therefore, proper lighting is necessary when growing Epipremnum aureum. Some gardening enthusiasts place the plant directly in a very sunny balcony, which is harmful to it because it is afraid of direct sunlight. If the leaves start to turn yellow at the edges and then spread to all the leaves, eventually turning the entire leaf yellow, it is due to excessive sunlight.
Under strong sunlight, the leaves are also prone to sunburn. Therefore, proper lighting is crucial when growing Epipremnum aureum. Too much sunlight can cause sunburn and yellowing of the leaves, while insufficient light can make the leaves smaller and yellow. Generally, we should ensure the plant gets two to three hours of sunlight per day, such as before 9 a.m. or after 4 p.m., or provide it with good shading, with over 50% shading. This kind of lighting is very suitable for Epipremnum aureum, allowing it to grow vigorously with large leaves and high luster.
2. Poor ventilation
In other seasons, Epipremnum aureum grows relatively slowly, but it grows very fast during the high temperatures of summer. If the ventilation is poor or if the pot is too large and the water does not dry out for a long time after watering, root suffocation can occur. After root suffocation, the leaves will gradually turn yellow. If the roots are suffocated for a long time, it can lead to root rot, and the leaves will rot. The initial sign is that the bottom leaves turn completely yellow, eventually causing the leaves to fall off and spreading very quickly.
Why do the leaves of Epipremnum aureum turn yellow in summer?
So if you find this situation, it is caused by poor ventilation and water that does not dry out for a long time, leading to root suffocation. We must ensure good ventilation when growing Epipremnum aureum, especially after watering. It's best to blow it with a fan to make the soil surface dry quickly, preventing root suffocation. Generally, it is not necessary to water too frequently. Usually, water it thoroughly when the potting soil is almost dry. This will not cause any problems.
If Epipremnum aureum grows normally in summer and yellowing leaves occur, these are the only two reasons: ventilation and lighting. If the leaves still turn yellow and grow slowly during routine care, it might be due to a lack of fertilizer. Make sure to supplement fertilizer regularly. Choose a fertilizer high in nitrogen content and not lacking in other elements, applying it once or twice a month. This is enough. Also, ensure proper watering and lighting, and your Epipremnum aureum will grow rapidly at home, hanging down from the pot to form a Epipremnum aureum hanging plant or training it to climb on a wall to form a Epipremnum aureum wall, which is very simple.
