The latest water lily leaves are black and rotten, how is it?

Water lilies with their elegant posture and brilliant, delicate flowers and quite ornamental value, pot-raised words to the summer flowering can not only bring us a pleasant experience, but also quite wild fun. But the method of raising water lilies in summer must be paid attention to, otherwise the plants are more likely to have black leaves and rot. So, what about the black and rotten leaves of water lilies? Today, the editor will discuss with you the reason why the leaves of potted water lilies are black and rotten.

The main reason for the blackening and decay of water lily leaves is that many potted friends think it is caused by fertilization or improper lighting. The real cause of this situation is not usually caused by too much fertilizer or too much concentration, nor is it caused by too much light or too long exposure to the sun. The most likely reason is that our water depth is not well controlled.

But how deep is the water? Is the water level too high or too low? In fact, the cause of black and rotten leaves of water lilies is generally due to the low water level, that is to say, too little water. Usually, it may be due to being too busy or forgetting to add water in time. When the water level remains relatively low for a long time, the leaves of water lilies gradually blacken and rot.

Although water lilies are suitable for planting in mud in spring, water lilies should not be raised too much in spring, and it is more appropriate to keep the water level relatively shallow, but this is also a practice in a relative state. But it should not be too shallow for a long time, because the plant is growing continuously, especially its stems and leaves are constantly drawn out. When the leaves spread out on the surface of the water, add water to the basin in time.

Not only to add water in time, with the continuous rise of water lily stems and leaves, we add water step by step, can not be done in one step, and can not be put in place in one step. The addition of water should be added layer by layer, so that the water level line and its stems and leaves always maintain a certain proportion, neither too high nor too low. Only in this way can we ensure that the water lilies can maintain their health and exuberant growth.

But if you enter the summer, as the temperature rises gradually, the weather will gradually become hot. Especially when water lilies are exposed to the hot summer sun, if the water level is low and the amount of water is small, the water temperature will rise sharply, causing the leaves to be burned, often rolling leaves and dried leaves until they rot. And as the leaves rot, so will their poles, and eventually the whole water lily may be suffocated.

Therefore, spring is suitable for raising water lilies at low water level, mainly because the temperature in spring is relatively low and the light intensity is not strong. Raising water in shallow water can raise the water temperature more quickly, thus accelerating the growth of water lilies. But if it is in the hot and hot summer, if the water lilies are raised in shallow water, it is easy to blacken and rot its stems and leaves, which is mainly due to the sharp rise in temperature in the basin leading to retting roots.

Therefore, we can not raise water lilies as shallow as in spring in summer, but should raise the water level in time to ensure that plants will not be sullen due to a sudden rise in temperature in the basin, so as to avoid blackening and decay of their stems and leaves. At the same time, potted water lilies should not be placed in the hot summer sun exposure, need proper shade, otherwise the leaves of the plant may wilt, or even curl the situation, will inevitably reduce the ornamental value of potted plants, but also may affect its normal growth.
