Calathea is a beautiful flower that is loved by many. During the maintenance process, some flower enthusiasts may find that the leaves of their calathea suddenly turn white. This not only affects the aesthetics of the flower but may also impact the growth of the plant. What are the reasons for the leaves turning white? How can we solve this issue? This article will answer these questions for you.
Reasons for Calathea Leaves Turning White1. Insufficient Water
Calathea is a plant that prefers a humid environment. If the soil remains dry for an extended period, it can cause the plant's roots to be unable to absorb enough water, resulting in the leaves turning white. You should water the calathea promptly to keep the soil moist.
2. Improper Fertilization
Excessive fertilization or uneven application of fertilizer can damage the calathea's roots, affecting the plant's nutrient absorption and causing the leaves to turn white. When fertilizing, be sure to apply the right amount evenly.
3. Insufficient Light
Calathea requires ample sunlight. If it is kept in a dark environment for an extended period, the plant may grow slowly and the leaves may turn white. Moving the calathea to a place with sufficient sunlight, such as a balcony or windowsill, can help improve this condition.
4. Disease and Pest Infection
The leaves of calathea turning white may also be due to disease and pest infections, such as leaf spot or powdery mildew. Prompt control measures should be taken to prevent the condition from worsening.
Methods to Solve Calathea Leaves Turning White1. Water Properly
When you find the calathea leaves turning white, first check if the soil is dry. If the soil is dry, water the plant promptly to keep it moist, but be careful not to overwater to avoid root rot.
2. Fertilize Properly
Fertilize according to the growth stage and needs of the calathea, using a complex or organic fertilizer to ensure the plant gets enough nutrients.
3. Increase Light Exposure
Move the calathea to a place with ample sunlight, such as a balcony or windowsill. If possible, you can also increase artificial lighting, such as using grow lights.
4. Control Diseases and Pests
If you suspect that the white leaves are due to disease or pest infection, take prompt control measures, such as spraying with appropriate pesticides, while also paying attention to strengthen daily maintenance to enhance the plant's disease resistance.
There are many reasons why calathea leaves turn white, but as long as we detect the issue early and take corresponding measures, we can effectively solve the problem. I hope this article can provide help to all flower enthusiasts, allowing your calathea to grow strong and healthy.
