What are the reasons for the cactus turning yellow?
Let's share the reasons why the cactus turns yellow, the remedial measures, and the small experience of green plant maintenance with four reasons analysis. Let's get to know each other.
There are generally 4 reasons for the cactus turning yellow, the first is lack of light, the plant likes light, and long-term insufficient light will affect photosynthesis, thus turning yellow, it should be exposed to the sun more. The second is too much water, the roots are prone to rot when soaked in accumulated water, and the rotting roots will cause the ball to turn yellow. The third is the hot and stuffy environment without ventilation, which will affect its regulatory function, and windows should be opened more. The fourth is low temperature, if sudden temperature drops are not noticed and kept warm, it will turn yellow after frostbite, usually kept indoors in winter.
Lack of Light
The cactus prefers sunlight during its growth period, and its original habitat is in desert areas, which naturally requires a lot of light. If kept in an environment with insufficient light for a long time during family cultivation, the plant itself cannot perform photosynthesis normally, which can lead to yellowing. It should be placed in a sunny area, either indoors or outdoors, as long as it is exposed to plenty of light every day. However, be careful not to suddenly move it to strong sunlight, but gradually increase the light so that the plant can slowly adapt and avoid adverse symptoms.
Too Much Water
The cactus has good drought resistance and does not require much water even during its growth process. Therefore, if too much water is added during maintenance, it is easy to accumulate water in the soil, and the roots will soon rot when soaked in water for a long time. The rotting roots will lose their normal ability to absorb water, which will directly lead to the ball turning yellow. When growing a cactus, water should be reduced, and it can grow normally as long as the soil is not particularly dry, maintaining a slightly moist state.
Hot and Stuffy
Although it likes sunlight and can tolerate drought, many people ignore the ventilation issue during maintenance. Plant growth requires a well-ventilated environment. If it is kept in a hot and stuffy environment for a long time, its normal growth will be affected, and over time, it will affect the plant's own regulatory function, leading to adverse growth symptoms, such as the ball turning yellow. Ventilation can be ignored when kept outdoors, but it should be paid special attention to when kept indoors, with windows opened more often to ensure air circulation.
Low Temperature
The plant does not tolerate severe cold well. During the winter, if placed outdoors without proper measures for insulation and warmth, it can be frostbitten and turn yellow. Especially in the northern regions of our country, more attention should be paid to insulation and not be left outdoors during winter. After entering winter, the cactus should be moved indoors promptly or a small shade shelter should be built for it. As long as it is not stimulated by low temperature or directly exposed to cold wind, it can usually survive the winter smoothly.
The detailed explanation provided above on the reasons for the cactus turning yellow and the remedial measures, as well as the four reasons analysis, hopes to bring you help in green plant management!
