Calla lilies are beautiful and elegant plants that can add a touch of sophistication to any garden. However, they are sensitive to cold temperatures and require proper winterizing to ensure their survival and healthy growth in the following season. Proper winter preparation involves using the right tools and techniques to protect your calla lilies from harsh winter conditions.
Essential Tools for Winterizing Calla Lilies
- Garden Fork or Spade: Used for carefully digging up the rhizomes without damaging them.
- Pruning Shears: Necessary for trimming dead or damaged foliage before storage.
- Storage Containers or Mesh Bags: For storing rhizomes in a cool, dry place.
- Damp Sphagnum Moss or Vermiculite: To keep rhizomes moist during storage.
- Labels or Markers: To identify stored rhizomes easily.
- Mulch or Straw: For protecting outdoor plants if winter is mild.
- Gloves: To protect your hands during digging and handling.
Tools and Techniques for Proper Winterization
Using the right tools is only part of the process. Proper techniques ensure your calla lilies survive winter and thrive in spring. Here are the steps and methods to follow:
Digging Up the Rhizomes
Use a garden fork or spade to gently loosen the soil around the calla lily. Carefully lift the plant, keeping the rhizome intact. Shake off excess soil and inspect for any signs of damage or disease.
Trimming and Cleaning
Trim back the foliage to about 2 inches above the rhizome using pruning shears. Remove any dead or rotting parts. This helps prevent disease during storage.
Drying and Storage
Allow the rhizomes to dry in a cool, dark place for a few days. Once dried, place them in a breathable container filled with damp sphagnum moss or vermiculite. Label each container for easy identification.
Outdoor Protection
If your winter is mild, you can mulch around the remaining outdoor calla lilies with straw or mulch to provide insulation. This can help protect the roots from extreme cold.
Conclusion
Proper winterizing of calla lilies requires the right tools and techniques to ensure their health and vitality. By carefully digging, trimming, and storing the rhizomes, and providing outdoor protection when necessary, you can enjoy beautiful calla lilies year after year. Gather your tools, follow these steps, and give your plants the winter care they need for success.
