My begonias seem to have gone wild . they are tall and very large leaf compared to when I first purchased them. the first year they were perfect but when I replanted the same bulb this year they grow tall and very large leafed . they still bloom but woul like to have les plant more flowers as I did the years before . thankyou I am an amatuer at this begonia growing but do so love the plant. Your suggestions would be gratefully appreciated.
