Why do the tips of bowl lotus buds turn black and wither after they emerge above the water surface?

Bowl lotus is deeply loved by gardeners for its highly ornamental value, but those who have grown bowl lotus in pots may have encountered the situation where the bud tips of bowl lotus grown as potted plants at home turn black and dry up after emerging above the water surface, which not only affects the normal growth of the bowl lotus, but also does not look good as a potted plant.

Observant gardeners may have noticed that bowl lotus growing in wild ponds generally rarely has bud tips turning black and withering after emerging above the water surface, so why is it that this situation tends to occur more easily in a home pot-growing environment? There must be a reason for this, and it should be a problem with the care environment.

The root cause of the tender buds of bowl lotus turning black and withering is dehydration. The reason is that in a home pot-growing environment, air circulation is often not as smooth as outdoors, and there is even less likely to be frequent wind. If we place the potted plant in an environment with poor ventilation and little sunlight, it not only cannot be exposed to wind to accelerate water transpiration, but also has weak photosynthesis, so the plant grows relatively weakly, and the tender buds cannot be kept moist, thus becoming dehydrated and developing abnormalities.

Of course, if it is under the effect of strong direct light and the environment is also poorly ventilated, this will further accelerate dehydration of the tender buds after they emerge from the water, so it can also cause the tender buds to gradually turn black and wither just after emerging above the water surface. Although bowl lotus relatively likes light, the tender buds are relatively afraid of prolonged strong direct light, especially when ventilation is poor, and the bud tips are very likely to become dehydrated.

Bowl lotus in nature generally does not have this situation, mainly because it is often exposed to wind and sunlight, and the transpiration on the water surface is obvious, which can well provide a moisturizing effect for the tender buds of bowl lotus just emerging above the water surface. Therefore, naturally, the tender buds will not become dehydrated and turn black and wither. But in a home growing environment there is often no wind, and if the light is inappropriate, it will often cause the above adverse symptoms.

Of course, it cannot be ruled out that it is due to deterioration of water quality or because we planted too early and the plant's root system has not yet grown well. Under these circumstances, it can also cause the plant's tender buds to easily turn black and wither as soon as they emerge above the water surface. Therefore, we should promptly find the crux of the problem and then take corresponding measures to avoid greater losses.
