In the Northern/Cold climates where it freezes during winter, tuberous begonias must be dug up and stored indoors during the winter. After the first light frost dig up the corms clean and store. In Southern/Warm climates areas that don’t have frost or rarely have frost, tuberous begonias go dormant on their own according to the day length. They usually reach that point in October or November. When the leaves start turning yellow and dropping and the stems also drop it is time to stop watering.1
These estimates for how long Tuberous begonia takes to sprout, grow and harvest are from real observations from real gardeners, right around the world.
