Growing calla lilies in hydrangea gardens can add a touch of elegance and vibrant color to your landscape. Combining these plants requires understanding their specific needs to ensure both thrive harmoniously. This article explores the best practices for cultivating calla lilies alongside hydrangeas, creating a stunning and healthy garden environment.
Choosing the Right Location
Selection of an appropriate location is crucial for successful growth. Calla lilies prefer a spot with partial to full sun, but they can tolerate some shade. Hydrangeas typically thrive in morning sun with afternoon shade, making a semi-shaded area ideal for both plants. Ensure the site has well-draining soil to prevent waterlogging, which can harm the roots of both plants.
Soil Preparation and Planting
Prepare the soil by mixing organic matter such as compost to improve fertility and drainage. Calla lilies prefer slightly acidic to neutral pH levels, while hydrangeas can change color based on soil pH. For vibrant blooms, aim for a pH of 6.0 to 6.5. Plant calla rhizomes about 4 inches deep and space them 12 inches apart. Hydrangea bushes should be spaced 3 to 4 feet apart to allow growth and airflow.
Watering and Mulching
Consistent watering is essential, especially during dry periods. Calla lilies require moist soil but should not sit in water, while hydrangeas need plenty of water to support lush foliage and blooms. Mulching around the plants helps retain soil moisture, regulate temperature, and suppress weeds. Use organic mulch such as bark or straw for best results.
Fertilizing Guidelines
Feed your garden with a balanced, slow-release fertilizer during the growing season. Apply a fertilizer high in phosphorus to encourage blooming. For calla lilies, use a fertilizer with a ratio like 10-20-10, and for hydrangeas, a similar formula works well. Fertilize every 4-6 weeks, adjusting based on plant response and growth conditions.
Pruning and Maintenance
Prune dead or damaged leaves from both plants to promote healthy growth and air circulation. Remove spent hydrangea flowers to encourage new blooms. Calla lilies die back after flowering; cut back the foliage to the ground and mulch to protect the rhizomes during winter in colder climates. Regular maintenance ensures your garden remains healthy and attractive throughout the season.
Pest and Disease Management
Monitor your plants regularly for common pests such as aphids, snails, and spider mites. Use organic or chemical controls as needed, following safety guidelines. Prevent diseases by avoiding overwatering and ensuring good airflow around plants. Remove any infected foliage promptly to prevent spread.
Seasonal Care and Tips
In colder regions, lift and store calla lily rhizomes indoors during winter to prevent frost damage. Hydrangeas may require winter protection, such as mulching or covering, depending on your climate. In the growing season, regularly check soil moisture and adjust watering accordingly. With proper care, your hydrangea garden with calla lilies will flourish year after year.
Conclusion
Growing calla lilies alongside hydrangeas can create a beautiful and diverse garden display. By selecting the right location, preparing the soil properly, and following consistent watering, fertilizing, and maintenance routines, you can enjoy vibrant blooms and lush foliage. With patience and care, your garden will become a stunning sanctuary of color and elegance.
