What to Do With Trailing Begonia Bulbs in the Fall?

Shade-loving trailing begonias (Begonia spp) are ideal for containers, window boxes and hanging baskets. In sub-freezing winter climates, they flower from early summer until the first frost. Lift their frost-tender bulbs in the fall for indoor overwintering and spring replanting.
  1. Lifting The Plant

    • Trailing begonia's leaves and stems will wilt and die within a few days of the first killing frost. Dig around the plant with a spade. Carefully lift the entire plant, leaving a small amount of soil on the bulb's roots.

    Curing the Bulb

    • Cut the foliage and all but 1 inch of stem. Place the bulb in a dark, cool location. Allow it to dry for two to three weeks.

    Cleaning the Bulb

    • Remove the soil from the cured bulb. Cut off the roots and stem remnant. Dust the bulb with fungicide powder. Ensure complete coverage by pouring the fungicide powder into a paper bag. Add the bulb and shake the bag well.

    Storing the Bulb

    • Cover the dusted bulb in vermiculite or dry peat moss. Store it at 40 to 50 degrees Fahrenheit. Replant it when the soil warms in spring.
