I have three 2 to 3 foot Begonia 'Carolina de Lucerna like this from too much propagating over the spring and summer.

I am not providing something it wants because none of them have bloomed. I have had several over the years from this same mother plant clippings, and none flowered. They go out for summer vacation, and grow well all winter. Could it be I am giving them too much light. Not enough fertilizer. Any tips would be so nice, because these use to bloom easily in my care years ago, and I am at a loss.
