Yellowing Leaves of Sempervivum tectorum in Water Culture: Four Reasons and Solutions
Sempervivum tectorum is very popular in some households. Look at its large leaves, they are indeed magnificent. We usually cultivate Sempervivum tectorum through water culture and soil culture. Among them, water culture is more common, but problems arise during this process. For example, what should we do when the leaves of Sempervivum tectorum in water culture turn yellow? Below, the editor will discuss the solutions, hoping to provide useful help.
1. -- Improper Lighting --
In the process of cultivating Sempervivum tectorum, due to the lack of sunlight, the plant's chlorophyll is difficult to form, causing the leaf color to gradually change from green to yellow. Additionally, too much light can burn the leaves directly, leading to yellowing.
Solutions:
So, in this case, we can place Sempervivum tectorum in an outdoor or阳台 with sufficient sunlight and good ventilation, and it will turn green in about a week. In summer, when the sunlight is too strong, appropriate shading is needed to prevent exposure.2. -- Unsuitable Temperature --
In winter, due to the cold temperature, the water temperature is relatively low since it is cultivated in water, which can easily cause the roots to freeze and injury, unable to absorb water and nutrients properly, leading to yellowing of the leaves.
Solutions:
In winter, we move Sempervivum tectorum indoors and keep the indoor temperature and humidity relatively stable. Take good warming measures to make the water temperature complement the plant's growth temperature, which is beneficial for the healthy growth of the leaves.3. -- Insufficient Water --
Since Sempervivum tectorum requires a large amount of water during its growing period, when the water in the container is insufficient, the plant cannot absorb enough water, gradually causing the leaves to turn yellow.
Solutions:
When changing water and adding water regularly, do not pour too much water into the water culture container. Keep the water level 2 to 5 centimeters below the base of the plant. Do not let all the roots soak in the water; Sempervivum tectorum's roots also need to breathe.4. -- Insufficient Fertilizer --
Generally speaking, Sempervivum tectorum is a fertilizer-loving plant. If too little fertilizer is applied during water culture, it can lead to yellowing of the leaves due to a lack of nutrients. Additionally, severe fertilizer damage can also cause yellowing.
Solutions:
Sempervivum tectorum enjoys fertilizer and can be fertilized once every two weeks or a month. For water culture, a nutrient solution is needed, which can be directly added to the water. This can be done when changing water every week. Use easily soluble fertilizers like urea and potassium dihydrogen phosphate for foliar application.Have you understood the detailed introduction of the yellowing of Sempervivum tectorum leaves in water culture and the four reasons and solutions provided above?
