ASK ALEXA: How do I overwinter my favorites?

• Bulbs, Corms, and Rhizomes: For plants like Begonias, Colocasia, Alocasia, and Caladium, allowing a light frost to knock them down signals the time to transition into a dormant state. Once frosted, carefully dig up the bulbs, corms, or rhizomes, remove excess soil, and store them in a cool, dry place for the winter.
• Pest and Disease Check: Before bringing in plants that can tolerate light frost but not freezing temperatures, such as Shrubs, tender Evergreens, and Succulents, conduct a thorough inspection for pests and diseases. Addressing any issues before indoor transition prevents potential infestations during the colder months.
• Cold-Tolerant Container Plants: Plants like Japanese Maples and Hydrangeas in containers can brave the winter in a garage or shed. Ensure they receive adequate light, even in their dormant state, and keep the soil slightly moist to prevent it from drying out completely. Shielding them from extreme temperature fluctuations helps maintain their vitality until it’s time to reintroduce them to the outdoor landscape come spring.

By incorporating these practices into your winter care routine, you’ll set the stage for a vibrant and thriving garden when the frosty days give way to the warmth of spring.
