Why Are Your Calla Lily Plant Leaves Turning Yellow:
Causes and Solutions

Calla lilies are a beautiful addition to any garden, with their striking white flowers and rich green leaves. However, if you notice that the leaves of your calla lily plant are turning yellow, it can be a cause for concern. In this article, we will explore the possible causes of yellowing calla lily leaves and provide solutions to help you restore your plant’s health.

Causes of Yellowing Calla Lily Leaves

1. Overwatering

One of the most common causes of yellowing calla lily leaves is overwatering. Calla lilies prefer moist but well-drained soil, and overwatering can lead to waterlogged soil and root rot. When the roots are damaged, the plant is unable to absorb nutrients properly, which can result in yellowing leaves.

2. Underwatering

On the other hand, underwatering can also cause the leaves of your calla lily plant to turn yellow. When a calla lily is not watered enough, it will start to wilt and dry out. This can cause the leaves to turn yellow and eventually die off.

3. Lack of Nutrients

Calla lilies require regular feeding to thrive. If your plant is not receiving enough nutrients, it may start to show signs of nutrient deficiency such as yellowing leaves. This can be remedied by fertilizing your calla lily with a balanced fertilizer.

4. Pests and Diseases

Pests such as spider mites and thrips, as well as fungal diseases such as powdery mildew and botrytis, can also cause yellowing leaves in calla lilies. These pests and diseases weaken the plant, making it susceptible to further damage or death.

Solutions for Yellowing Calla Lily Leaves

1. Adjust Watering Habits

To address overwatering or underwatering issues, make sure to adjust your watering habits accordingly. Water your calla lilies deeply once or twice a week, depending on the weather and soil conditions. Ensure that the soil is well-draining and has good air circulation.

2. Provide Proper Nutrients

Fertilize your calla lilies with a balanced fertilizer every three weeks during the growing season. This will provide your plants with the necessary nutrients to grow healthy and strong.

3. Address Pests and Diseases

If you suspect that pests or diseases are causing yellowing leaves on your calla lilies, take action immediately. Remove affected leaves or plants if necessary and treat with an appropriate pesticide or fungicide.
