Reason: Proper watering and fertilization are required in the maintenance process of Zygocactus indica. Once the proper dosage is not paid attention to, the root will rot, affecting the transport function. It is difficult to supply water and nutrients, and the leaves will become red.
Solution: Usually pay attention to the control of watering and fertilization, dig out the plant to check the roots, cut off the rotten roots, and re-cultivate and maintain.
Reason: If the soil is not changed for a long time, the soil will be alkaline, and the growth of the plant will be affected, resulting in red leaves.
Solution: If you find that the soil can't be dealt with, you need to change the soil in time and replace it with loose acid soil.
Reason: If the leaves appear red in winter, it is likely to be frostbite.
Solution: In winter, we should pay attention to keeping warm, not too cold, and the surrounding growth temperature should be kept at about 10 degrees.
Reason: If it is kept in a place with strong light, the leaves will turn red under the exposure to the sun. Not only the exposure to the sun, but also the long-term absence of the sun and the dark state will cause the leaves to turn red.
Solution: It is necessary to control the illumination during maintenance. When there is a lack of sunlight, it is necessary to see the light in time. When the light is too strong, it is necessary to take shading measures.
Reason: Long-term non-fertilization will also cause nutrient loss, especially the lack of phosphate fertilizer, which will lead to red leaves.
Solution: It is necessary to supplement phosphate fertilizer in time according to the needs of growth to meet the needs of nutrients.
