Calla lilies, with their elegant trumpets and striking colors, are a beloved addition to any garden. But as the days shorten and temperatures drop, these tropical beauties face a challenge. So, how do you ensure these stunning plants survive the winter and return in full glory next spring? This guide will walk you through the steps of how to store calla lily over winter, ensuring a vibrant return of these captivating blooms.
Understanding Calla Lily’s Winter Dormancy
Calla lilies, native to South Africa, thrive in warm climates. When temperatures dip below 50°F (10°C), they enter a period of dormancy, halting their growth and preparing for the colder months. This natural process is essential for their survival.
Deciding Your Storage Method: Digging or Leaving in Place?
The best storage method for your calla lilies depends on your climate and personal preference. Here’s a breakdown:
1. Digging and Storing Indoors:
- Best for: Regions with harsh winters (temperatures below freezing) or gardeners who prefer a guaranteed return of their plants.
- Process:
- Digging: Once the foliage begins to yellow and die back, carefully dig up the bulbs.
- Cleaning: Shake off excess soil and gently remove any dead foliage.
- Drying: Allow the bulbs to air dry in a cool, dry place for a few days.
- Storing: Place the dried bulbs in a container filled with peat moss, vermiculite, or dry sawdust. Store in a cool, dark, and dry location with temperatures between 40°F and 50°F (4°C and 10°C).
2. Leaving in Place with Protection:
- Best for: Mild winter climates where temperatures rarely dip below freezing.
- Process:
- Mulching: Apply a thick layer of organic mulch (shredded bark, leaves, or straw) around the base of the plants. This will insulate the bulbs and protect them from frost.
- Winter Protection: In areas with occasional frosts, consider additional protection like burlap sacks or plastic sheeting placed over the plants.
Preparing Calla Lilies for Winter Storage
Regardless of your chosen method, there are some essential steps to prepare your calla lilies for winter storage:
1. Gradual Transition: Avoid abrupt changes in temperature. As the weather cools, gradually reduce watering to allow the plants to enter dormancy naturally.
2. Stop Fertilizing: Once the plants begin to show signs of dormancy, cease fertilizing.
3. Cut Back Dead Foliage: Once the foliage has completely died back, cut it down to the ground level. This helps prevent disease and promotes healthy storage.
Caring for Calla Lilies During Winter Storage
Once your calla lilies are in storage, it’s crucial to monitor their condition regularly:
1. Check for Moisture: Periodically check the storage medium to ensure it remains dry. If it feels damp, gently remove the bulbs and allow them to air dry before returning them to storage.
2. Monitor for Pests: Inspect the bulbs for any signs of pests or disease. If you notice any issues, separate the affected bulbs and treat them accordingly.
3. Maintain Ideal Conditions: Ensure the storage area remains cool, dark, and dry throughout the winter. Avoid fluctuating temperatures, as this can stress the bulbs.
Reviving Your Calla Lilies in Spring
As spring approaches, it’s time to bring your calla lilies back to life:
1. Repotting or Planting: When the threat of frost has passed and temperatures warm up, repot your bulbs or plant them directly in the garden.
2. Gradual Acclimatization: Don’t rush the process. Gradually acclimate the bulbs to outdoor conditions by placing them in a sheltered location for a few days before exposing them to full sun.
3. Water and Fertilize: Once the bulbs have established themselves, resume regular watering and fertilization to encourage vigorous growth.
Enjoying the Beauty of Your Calla Lilies
With proper care and storage, your calla lilies will reward you with their vibrant blooms season after season. Remember, these plants are a testament to the beauty and resilience of nature. By understanding their needs and providing them with the appropriate care, you can enjoy their stunning presence year after year.
Beyond the Basics: Tips for Success
1. Selecting Healthy Bulbs: When purchasing calla lily bulbs, choose firm, plump bulbs with no signs of damage or disease.
2. Disease Prevention: To prevent fungal diseases, ensure the storage area is well-ventilated and the bulbs are dry.
3. Variety Matters: Some calla lily varieties are more cold-hardy than others. Choose varieties suitable for your climate or consider growing them in containers for easier winter storage.
