Calla lilies are a popular choice for adding elegance and beauty to gardens and floral arrangements. Known for their striking trumpet-shaped flowers, they typically bloom in late spring to early summer. However, gardeners often seek ways to extend the blooming season to enjoy their beauty longer. One effective method is using companion plants to create a favorable environment and stimulate prolonged flowering.
Understanding Calla Lily Blooming Habits
Calla lilies (Zantedeschia spp.) are perennial plants that thrive in warm, moist conditions. They usually bloom from late spring through summer, but their flowering period can vary based on climate, care, and surrounding plants. To extend their bloom, gardeners can manipulate environmental factors and plant companions that promote healthy growth and flowering.
Choosing the Right Companion Plants
- Marigolds: Their vibrant colors attract pollinators and help deter pests, creating a healthier environment for calla lilies.
- Hostas: Their large leaves provide shade and protection, reducing stress on calla lilies during hot weather.
- Ferns: Adding ferns increases humidity and provides a lush backdrop, encouraging longer blooming periods.
- Sweet Alyssum: Its low-growing habit and fragrant flowers attract beneficial insects that support pollination.
- Coral Bells (Heuchera): Their colorful foliage adds visual interest and can help maintain soil moisture levels.
Planting and Arranging Companion Plants
When planting companion plants, consider their growth habits and environmental needs. Arrange taller plants like hostas and ferns behind the calla lilies to provide shade and protection. Place shorter plants such as marigolds and alyssum in front to enhance visual appeal and attract pollinators. Ensure all plants have similar soil and moisture requirements for optimal growth.
Care Tips to Extend Blooming Season
- Consistent watering: Keep the soil evenly moist but not waterlogged to support healthy growth.
- Proper fertilization: Use a balanced fertilizer during the growing season to promote continuous flowering.
- Mulching: Apply mulch around the plants to retain soil moisture and regulate temperature.
- Deadheading: Remove spent flowers to encourage new blooms and prolong the flowering period.
- Temperature management: Protect calla lilies from extreme cold or heat, which can shorten their blooming time.
Additional Tips for a Longer Blooming Period
In addition to planting companions and proper care, consider planting calla lilies in containers. This allows for better control over environmental conditions and easy relocation to optimize sunlight and temperature. Also, stagger planting times by starting new bulbs at intervals to ensure a continuous display of blooms throughout the season.
Conclusion
Using companion plants is an effective strategy to extend the blooming season of calla lilies. By selecting suitable plants, arranging them thoughtfully, and providing consistent care, gardeners can enjoy their elegant flowers for a longer period. Experimenting with different combinations can also add variety and visual interest to your garden throughout the growing season.
