What to do if the leaves of water lilies turn black

Causes of blackening

There are actually many reasons why water lily leaves turn black. This phenomenon will occur if too much fertilizer is applied during the growth period. Too much fertilizer will reduce the number of water lily leaves and reduce the ability to absorb water, causing the leaves to turn black and burn.

The second reason why water lily leaves turn black is infection by bacteria. If the water lily is infected with bacteria, various problems will arise, including blackening of the leaves.

In addition, when there is insufficient light and it is too humid, the leaves of water lilies are also prone to turn black, because the growing environment of water lilies is too damp at this time, which will cause blackening and even rot in severe cases.

Another reason is that the water quality is not clean. When the water is relatively dirty, the leaves of water lilies tend to turn black.

What to do if you turn black

If there is too much water and fertilizer when growing water lilies, you can change the water immediately. When changing the water, be careful to replace half of it first to keep the water temperature similar. If too much base fertilizer is applied during planting, it is necessary to repot and change the soil.

During the growth period of water lilies, if they are infected with pathogens and have leaf diseases, you need to cut off the blackened leaves and then spray them with a solution of carbendazim.

In addition, it is necessary to increase sunlight. If the water of the water lily is dirty, replace it with clean water. When changing the water, pay attention to the water temperature to avoid changes in the pH value of the water.
