|We live in SW Florida. Will the tuberous begonia bloom all year?
|Tuberous begonias need a resting period, no matter where they grow. When the leaves and stems begin to wilt, withhold water. After the stems fall off, dig the tuber and store it in a cool place. When new little buds begin to sprout, repot and resume regular watering. New stems and leaves will appear first, followed by blossoms.
