Tuberous begonias, prized for their spectacular flowers, store energy in underground tubers during their growing season. To overwinter them, we need to protect these tubers from freezing temperatures.

What You’ll Need to Overwinter Begonias – hand trowel or shovel – peat moss or vermiculite – Box or bin

Wait until the first frost has blackened the foliage. This signals the plant to send its energy down to the tubers.

Carefully dig up the tubers, leaving some soil around them to prevent damage.

Cut off the stems about an inch above the tubers and let them cure in a cool, dry place for 2-3 weeks. This allows the cuts to heal and the tubers to dry.

Gently remove any remaining soil from the cured tubers. Place them in a box filled with a moisture-absorbing material like peat moss, vermiculite, or sawdust.

Store the box in a cool, dark place with good ventilation. A temperature range of 40-50°F is ideal. Check on them periodically to ensure they aren’t rotting.
