What to Do When Water Hyacinth Leaves Turn Yellow? Causes and Treatments for Yellow Leaves in Potted Plants
Hydroponic plants are loved by gardening enthusiasts for being clean and stylish, and they are also very suitable for growing in pots at home in modern society. But many hydroponic plants on the market are relatively expensive, and many friends are reluctant to buy them, but there are also very cheap hydroponic plants. Today, the editor recommends for everyone a cheap and high-quality aquatic plant suitable for growing in pots at home——water hyacinth. Because this plant has high ornamental value for both its flowers and leaves, growing it at home can also provide a very nice decorative effect.
But water hyacinth growing in the wild can bring great harm to the ecological environment, because it is an invasive species that not only affects the growth of underwater organisms but also consumes a large amount of dissolved oxygen in the water, causing organisms living symbiotically with it to die from lack of oxygen, thus seriously disrupting the ecological balance of its environment. Therefore, this plant is only suitable for pot cultivation, and it also has the ability to purify wastewater.
Because water hyacinth has a strong ability to adapt to the environment, the method of growing it as a potted plant is also very simple, but some gardening enthusiasts still find that the water hyacinth they grow at home develops yellow leaves, seriously affecting its ornamental effect. So, what should be done when potted water hyacinth leaves turn yellow?
In fact, the causes of yellowing leaves in water hyacinth are mainly due to two aspects:
On the one hand, this plant itself likes to grow in dirty water. Once the water quality is too clean, the plant will develop yellow leaves due to lack of nutrients. So, for this situation, we only need to give it some “dirty water,” and the dirtier the water, the easier it is to grow well. River water, pond water, etc. can be used.
On the other hand, although this plant has extremely strong reproductive ability and good water tolerance, it is not cold-resistant. If the winter temperature is low and necessary warming measures are not taken, it can easily suffer frost damage. After the plant suffers frost damage, its stems and leaves will appear withered and yellow. So, in order to avoid this phenomenon, when the winter temperature is low, it should be placed in a warm place indoors, and after it becomes clear outside, it can be moved outdoors to fully receive light.
Speaking of light, in fact, if water hyacinth is kept in a shaded growing environment for a long time, it may also develop drooping and soft leaves or scorched leaf edges and withered yellow leaves due to long-term lack of light. However, this is generally not the main cause of yellowing leaves in water hyacinth. (Author: Xiaoshu 2017-08-20 22:30)
