As the days grow shorter and temperatures begin to drop, it’s time to prepare your calla lilies for the winter months. Proper pre-winter care ensures that these elegant plants survive the cold and bloom beautifully again next season.
Assess Your Calla Lilies
Start by inspecting your calla lilies. Look for any signs of disease, pests, or damage. Remove any dead or yellowing leaves to promote healthy growth and prevent disease spread.
Reduce Watering
Gradually decrease watering over the course of a few weeks. Allow the soil to dry out completely before the first frost. Overwatering during winter can cause bulb rot.
Stop Fertilizing
Cease fertilizing your calla lilies as they prepare for dormancy. Fertilizer encourages new growth, which is undesirable before winter.
Prepare for Digging or Mulching
If you live in an area with cold winters, consider digging up the rhizomes. Carefully lift them from the soil, brush off excess dirt, and allow them to dry in a cool, dry place. Alternatively, apply a thick layer of mulch around the base of the plants to insulate the roots.
Proper Storage of Rhizomes
Store the dried rhizomes in a paper bag or mesh container in a cool, dark, and well-ventilated area. Check periodically for signs of rot or pests, and remove any damaged rhizomes.
Protect Outdoor Plants
If you choose to leave your calla lilies in the ground, cover the area with a thick layer of mulch, straw, or leaves. This insulation helps protect the rhizomes from freezing temperatures.
Additional Tips
- Label your rhizomes for easy identification in storage.
- Ensure good drainage in the planting area to prevent waterlogging.
- Monitor weather forecasts for early frosts and act accordingly.
Preparing your calla lilies now will help ensure a healthy and vibrant display next season. Taking these steps can make all the difference in their winter survival and future blooms.
