To keep calla lilies upright and growing strong, it is crucial to follow proper cultural practices. These elegant flowers require specific care to ensure they thrive in your garden or landscape.
1. Good Drainage: Calla lilies prefer well-draining soil to prevent waterlogging, which can lead to rotting of the bulbs. If your soil tends to retain moisture, consider amending it with organic matter such as compost or well-rotted manure to improve drainage.
2. Full Sun: Calla lilies thrive in full sun, which typically means they should receive at least six hours of direct sunlight each day. However, they can tolerate partial shade, especially in hotter regions where some afternoon shade can help prevent wilting.
3. Soil Preparation: Before planting your calla lilies, it is beneficial to prepare the soil. Work in compost or well-rotted manure to enrich the soil with organic matter. This will provide essential nutrients for the plants and improve soil structure, aiding in drainage and root development.
4. Mulching: Once your calla lilies are in the ground, apply a layer of organic mulch around the plants. Mulching helps retain moisture in the soil, keeping it consistently moist during the hot summer months. It also helps suppress weed growth, which can compete with the lilies for nutrients and water.
5. Watering: Calla lilies require consistently moist soil, but they do not tolerate waterlogged conditions. Water deeply and thoroughly, allowing the soil to dry slightly between watering sessions. Aim to keep the soil evenly moist but not overly wet.
6. Staking: If you notice that your calla lilies are struggling to stay upright, particularly in windy areas or if the flower stalks are long and heavy, staking can provide support. Insert a sturdy stake near the plant and gently tie the stem to the stake using soft garden twine or plant ties. Be careful not to damage the stem while securing it.
7. Deadheading: To encourage continued blooming and prevent energy wastage, remove faded flowers by cutting the stem just above the base of the plant. Deadheading also helps maintain a tidy appearance and prevents the formation of seed pods.
8. Winter Care: In colder regions, calla lilies may not be hardy and will require protection from frost. After the first frost, cut back the foliage to about two inches above the ground, carefully dig up the bulbs, and store them in a cool, dark, and dry place for the winter. It is essential to check the bulbs periodically for any signs of rot or damage during storage.
By following these guidelines and providing proper care, you can help your calla lilies grow strong, upright, and produce beautiful blooms throughout the growing season. Remember to observe your plants closely, adapting your care routine as needed based on your specific garden conditions and the behavior of the lilies themselves.
