Overview

Begonias are flowers often selected by home owners and landscapers for their tolerance to shade. They produce blooms all summer long and are available in a wide range of colors, from reds to salmon to white. While begonias are tolerant of shade and cooler climates, they do not handle freezing temperatures very well. If you live in a northern climate where the winter temperatures often dip below freezing, you will want to dig up your begonia tubers and put them in storage until spring rolls around again.

Step 1

Wait until after the first frost to dig up your begonia tubers for storage, when the foliage has turned yellow.

Step 2

Cut any top growth down to 5 inches, and carefully dig the tubers out of the soil with a spade. Leave any soil that may be attached to the tuber intact.

Step 3

Lay out a sheet of newspaper on a counter or tabletop, and set the begonia tubers on the paper to dry for three weeks. This drying process should be done in a cool area, away from direct sunlight.

Step 4

Remove all dried dirt, and clip roots and stems off the dried begonia tubers.

Step 5

Place the tubers in a paper bag, and sprinkle them with fungicide, available at any lawn and garden center. Fungicide is also sometimes referred to as bulb dust. Fold the top of the bag down and shake the tubers and fungicide up for two to three minutes, so that the dust covers all of the tubers. Follow package instructions for the amount to use.

Step 6

Fill a gallon size plastic bag with peat moss, and then place the tubers in the bag, making sure each one is surrounded by some peat moss.

Step 7

Poke 10 air holes in the plastic bag, and store it in a cool location, where the temperature remains at approximately 50 degrees Fahrenheit.

Tips and Warnings

  • Never wash your begonia tubers before storage, as any excess moisture can cause them to rot.
