Care During Calla Lily Season

Proper care is essential during the calla lily season to ensure healthy and abundant blooms:

Watering:

Water regularly, especially during hot and dry weather. Allow the soil to dry slightly between watering to prevent waterlogging.

Fertilizing:

Fertilize every 2-3 weeks with a balanced fertilizer. Use a slow-release fertilizer to provide nutrients gradually.

Sunlight:

Calla lilies prefer bright, indirect light. Avoid exposing them to intense direct sunlight, as this can scorch the foliage.

Temperature:

Calla lilies are heat-tolerant but prefer temperatures below 90°F (32°C). Protect them from frost and cold winds.

Pests and Diseases:

Calla lilies are generally pest-resistant, but they can be susceptible to aphids, thrips, and spider mites. Treat infestations promptly using appropriate pesticides.

Calla lilies are stunning in bouquets, whether as focal flowers or accent blooms. Their long stems and elegant shape create a refined and sophisticated look.

Arrangements:

Use calla lilies in mixed arrangements with other flowers, such as roses, hydrangeas, or ferns, to create visually interesting displays.

Centerpieces:

Calla lilies make beautiful and elegant centerpieces for weddings, parties, or special occasions. Arrange them in tall vases or shallow bowls.

Gardens:

Massed plantings of calla lilies create a vibrant and eye-catching display in gardens. Use contrasting colors or varieties to add depth and interest.
