Caladiums: A Guide to Winter Care and Storage
Introduction
Caladiums are beautiful plants known for their large, colorful leaves. They are native to South America and prefer warm temperatures. In cooler climates, special care is needed to protect caladiums during the winter.
Winter Care
Caladiums are winter hardy to USDA zone 9, meaning they can survive outdoors in these areas. However, even in these zones, a heavy layer of mulch (3 inches) is recommended to protect the bulbs from cold temperatures.
In USDA zones 8 and lower, caladium bulbs need to be dug up and brought inside for the winter. Dig up the bulbs when temperatures consistently drop below 60 degrees Fahrenheit. Leave the foliage attached and avoid removing any dirt from the roots.
Store the plants in a cool, dark place for 2 to 3 weeks. This process will cure the bulbs and cause them to go dormant. After a few weeks, cut the tops off level with the soil line. Brush away any loose soil, cut out any rotted areas, and apply a fungicide.
Storing Caladium Bulbs
Store caladium bulbs in a dry place at a temperature of 50 degrees Fahrenheit. It helps to keep them in sand or sawdust to prevent them from drying out. Keep them there until spring.
Planting Caladium Bulbs
Plant caladium bulbs outdoors after the last chance of frost. In areas with short growing seasons, you can start them indoors earlier. Caladiums can also be grown and stored in containers over winter.
Watering Caladiums in Winter
When storing caladiums in containers, limit watering to once monthly to prevent them from drying out completely. Keep them in a somewhat dark location.
Resuming Care in Spring
Once warm temperatures and longer days return in spring, the plant should begin regrowing. At this time, you can give it additional light and resume normal care.
Additional Tips
- When digging up caladium bulbs, use a sharp shovel to avoid damaging the roots.
- If you live in a cold climate, consider storing caladium bulbs in a refrigerator over winter.
- Be sure to inspect caladium bulbs for any signs of rot or disease before storing them.
- Caladiums are toxic to pets, so keep them out of reach of animals.
Conclusion
By following these tips, you can successfully care for caladiums during the winter and enjoy their beautiful foliage for many years to come.
