Calla lilies are elegant and striking plants that can add a touch of sophistication to any garden or floral arrangement. However, their tall and sometimes fragile stems can benefit from staking to ensure they grow upright and remain healthy. Knowing when and how to stake calla lilies is essential for supporting their growth and maximizing their beauty.
Understanding Calla Lily Growth
Calla lilies (Zantedeschia aethiopica) typically grow from rhizomes and produce large, trumpet-shaped flowers. They can reach heights of 2 to 3 feet, depending on the variety and growing conditions. As they grow taller, their stems may become top-heavy, especially when flowering profusely or in windy environments. Proper support helps prevent the stems from bending or breaking.
When to Stake Calla Lilies
The ideal time to stake calla lilies is early in their growth cycle, before they start to flower. This proactive approach ensures the stakes provide support as the plant matures. Signs that indicate the need for staking include:
- Stems beginning to lean or bend under their own weight
- Heavy flowering causing stems to droop
- Growing in windy or exposed locations
- Plants reaching heights of over 1.5 feet
Choosing the Right Stakes
Select stakes that are sturdy and tall enough to support the full height of your calla lilies. Common options include:
- Wooden stakes
- Plastic or fiberglass stakes
- Bamboo stakes
Ensure the stakes are smooth to prevent damage to the stems and are anchored securely into the ground.
How to Stake Calla Lilies
Proper staking involves careful placement and gentle tying to avoid damaging the plant. Follow these steps:
- Insert the stake into the ground about 2-3 inches away from the base of the plant.
- As the plant grows, gently tie the stem to the stake using soft garden twine or plant ties, avoiding constriction.
- Tie at multiple points along the stem if necessary to provide even support.
- Remove ties once the plant is established and no longer needs support, usually after flowering.
Additional Tips for Supporting Calla Lilies
Supporting your calla lilies not only prevents damage but also encourages upright growth and better flowering. Consider these additional tips:
- Use biodegradable ties to minimize environmental impact.
- Regularly check ties and stakes for stability and adjust as needed.
- Mulch around the base to retain moisture and reduce stress on the plant.
- Ensure the planting site has well-draining soil to prevent root rot.
Conclusion
Knowing when and how to stake calla lilies is key to supporting their growth and enhancing their natural beauty. Early support, choosing appropriate stakes, and gentle tying practices will help your calla lilies thrive and produce stunning blooms season after season.
