|I have some tuberous begonias and they are still blooming (in pots). However, I moved the pots into our garage when outside temperatures dropped into the 30 s. What steps should I take to protect the plants/bulbs during the winter months?|
|The customary way to overwinter tuberous begonias is to remove the tubers from the ground (or containers) and spread them out in flats, leaving the soil adhering to the roots. Place in a sunny, airy spot to dry. Once the leaves and stems have died back, remove the foliage and excess soil and store in dry sand or peat moss at a temperature of 40 - 50F for the winter.
