In this article, we'll explore the reasons behind yellowing leaves and share some tips on how to prevent and treat the issue.

Understanding Calla Lilies

Calla lilies are native to South Africa and are members of the Araceae family. These plants are grown for their showy flowers that come in a range of colors, including white, yellow, pink, and red. The flowers are typically trumpet-shaped and have a distinctive spadix, which is a spike covered in small flowers.

Calla lilies prefer moist soil and moderate temperatures, making them ideal for growing indoors or in outdoor containers. They can also be grown in the ground in mild climates.

Common Causes of Yellow Leaves on Calla Lilies

1. Overwatering
   • Overwatering can lead to root rot, which can cause leaves to turn yellow and eventually die.
   • To prevent overwatering, allow the top inch of soil to dry out before watering again.
2. Underwatering
   • Lack of water can also cause yellow leaves.
   • Make sure to water your calla lilies regularly, especially during hot weather.
3. Poor Soil Drainage
   • Calla lilies require well-draining soil to prevent root rot.
   • Use a potting mix that contains perlite or vermiculite to improve drainage.
