Overwintering Begonias Indoors: Tips for Tuberous and Fibrous Types

Know Your Begonia Type

Tuberous begonias can be stored dormant in a cool (40–50°F), dry basement. Keep tubers in peat or vermiculite; check occasionally for shriveling.

Fibrous (wax) and rhizomatous begonias grow well as houseplants in bright windows (south or west). They may look ragged by spring but recover quickly outdoors.

General Indoor Care

• Bright, indirect light.
• Water when top inch of soil is dry.
• No fertilizer in winter.
• Watch for pests (mealybugs, spider mites).

Move outdoors after frost danger passes, acclimating gradually.
