What should I do if the leaves of evergreen turn yellow?

Known for its tenacious vitality and evergreen leaves, Dieffenbachia is a popular foliage plant. But during the maintenance process, yellowing of leaves is a common problem. Let’s learn together what to do when the leaves of the evergreen turn yellow?

1. Normal aging

Yellowing of the leaves of the Dieffenbachia plant may be part of the natural aging process. As the plant grows, the bottom leaves may gradually turn yellow. In this case, just prune off the yellow and aging leaves regularly to promote the growth of new leaves.

2. Watering problem

The roots of the evergreen are fleshy and easily damaged by waterlogging. Therefore, watering should follow the principle of "don't water unless the soil is dry", keep the soil slightly moist, and avoid over-wetting or waterlogging.

3. Lighting management

Dieffenbachia prefers a semi-shaded environment and should not be exposed to strong direct sunlight for a long time. More than 60% shade should be provided in spring, summer and autumn, and can be reduced to 40% shade in winter.

4. Temperature control

The suitable growth temperature for evergreen is 15-18℃, and the minimum temperature should not be lower than 5℃ to prevent frost damage. In winter, the evergreen should be moved to a warm place indoors and the temperature should be kept above 10℃ to ensure safe wintering.

5. Fertilization method

Excessive fertilization may cause the leaves of the evergreen to turn yellow. Liquid fertilizer should be applied every 10-15 days during the growing season, and fertilization should be stopped in winter to avoid damaging the root system.

6. Clean the blades

Keeping your dieffenbachia leaves clean is essential to the health of the plant. Accumulated dust may affect photosynthesis and cause leaves to turn yellow. Periodically wipe the blades gently with a damp cloth or soft brush to remove dust.

In general, Dieffenbachia is a popular foliage plant, but during the maintenance process, the leaves often turn yellow. The above are some common causes and corresponding treatment methods.
