Question:

What type of planting site do tuberous begonias prefer?

Answer:

Tuberous begonias perform best in moist, well-drained soils in partial shade.  Choose a site sheltered from strong winds.  In the home landscape, locations that receive morning sun and afternoon shade are often excellent planting sites.  Use a well-drained potting mix when planting tuberous begonias in window boxes, hanging baskets, and other containers.  When planting tuberous begonias, place plants at the same depth as they were grown in the container.  Planting them deeper than previously grown may encourage the buried portion of the stem to rot.
