What is the reason why the leaves of the lotus turn black and wither?

Bowl lotus is an aquatic plant with extremely high ornamental value. Its flowers are rich in colors and various shapes, giving people a fresh and refined feeling. Many flower lovers like to grow them. So what is the reason why the leaves of the water lily turn black and wither during the care of the water lily? Let’s learn more about it below.

1. Insufficient light

Bowl lotus needs sufficient light for photosynthesis. Insufficient light will affect the growth of leaves and cause them to turn black. The solution is to place the water lily in a place with sufficient light in time, but avoid direct sunlight.

2. The soil is alkaline

If the soil is alkaline, it will affect the plant's absorption of some rare elements. The leaves will turn black and wither if they cannot absorb excess nutrients. At this time, we can add some ferrous sulfate, which can not only change the pH value of the soil but also supplement the iron element.

3. Improper fertilization

Excessive fertilization will cause the soil to be too fertile, affecting the leaves' ability to absorb water, or long-term lack of fertilizer will lead to poor leaf growth, all of which may cause symptoms similar to blackening and withering of leaves. The solution is to choose aquatic plant fertilizers specially designed for aquatic flowers , spread the fertilizer evenly on the surface of the pool or hydroponic water, allow the fertilizer to gradually dissolve into the water, and provide it to the plants for absorption. Be careful to apply the fertilizer correctly according to the package instructions and do not overdo it.

4. Water quality issues

Unsuitable water quality will affect the growth of water lilies and cause the leaves to turn black. The water quality should be changed regularly to keep the water clean. Another reason is lack of water. If there is less water in the pot and the water lily is not watered in time, the leaves of the water lily will turn black. Therefore, please note that the water lily must not lack water during its growing season.

5. Bacterial infection

When planting water lilies, if the soil is not sterilized or the water is not clean, bacteria will breed, affecting the growth of the water lilies and causing the leaves to turn black. After the disease occurs, you should cut off the bad leaves in time and buy special treatment agents to spray on the leaves. The concentration should not be too high and you can spray it several times. In addition, lotus seed rot and seedling burning will also cause the leaves to turn black, so it is also necessary to pull out those lotus seeds that show symptoms in time.

In general, there are many reasons why the leaves of water lilies turn black and wither, and they can usually be solved by addressing the symptoms. During daily maintenance, pay attention to turning the soil frequently, checking for root rot, maintaining the acidity and alkalinity balance of the soil, and doing a good job of watering and fertilizing, so that the plants will basically have no problems.
