With their whimsical shape and delicate scent, calla lilies are a beautiful addition to any home or garden. Although the beautiful flowers are relatively easy to care for, stress on the plant can result in a calla lily with yellow leaves.
Watering the calla lily too much or too little can cause the leaves to yellow. If you water the plant too much and then allow it to dry out the following week, the plant often responds by allowing lower leaves to yellow and die to reduce water loss. When caring for a calla lily, keep the soil moist at all times. However, do not allow water to sit on top of the soil.
In warm climates, calla lilies should be planted in an area that is partially shaded. In all other climates, plant the flower in an area with plenty of sun. Either way, the flower needs plenty of sunlight to avoid yellowing leaves.
The Pacific Callas website recommends fertilizing your calla lily once a month with an all-purpose fertilizer. Fertilizing the plant too much often results in burnt leaf edges. However, fertilizing the plant too little often results in yellow leaves.
If the calla lily’s leaves begin to yellow, gently remove them. If leaves continue to yellow regularly, you may need to move the plant to a different location or adjust its watering schedule.
