I saw this summer by a friend on Salt Spring island her Begonia growing on a full South facing deck. I have one shaded corner where I usually grow one basket. I moved it indoors now , first time, by South facing window. Will they go on growing? They are very long , can I cut them to stimulate growth and flowering? Can I replant the cut tube as half my pot is empty due to previous corner position. Will they still die in a few weeks as they did outdoors? Will the shock from shade to sun kill them? Should I put them near in indirect sunlight? I am rather an instant gardener. The blooms are very pretty although, last year had a Dragon begonia, (if I recall the name correctly) that was phenomenal but could but find one in any of the south Marine drive nurseries Thank you.
Looks in your picture like this year's model is a tuberous begonia. can you grow tuberous begonias inside - Search (bing.com)
