| I have the same issue. Mine is 1 year old, it bloomed last summer and fall and then the leaves dropped. I only have leaves at the very end. The stems are woody and the plant is leggy. Its an Begonia Orange Rubra, which is an angel wing. Its in a south facing window, but the light is filtered by a shade. I only water when its dry. It has not been well fed all winter. I just started feeding it with algoflash. Anyway, I spoke to a horticulturist and he said that if I look carefully, I should soon see buds on the stems where new leaves will grow. Sure enough, on the stem there are little points. He told me to keep feeding it and it will be nice and lush. Once growing starts, I can prune it to get a nice shape. Also, as an experiment, I snipped one of the stems just above the first joint. I took the stem and put it in some soil to see if it roots. I thinks its working. But my original plant looks even worse. I read elsewhere that its ok to prune these to the roots. I am too scared to try it. Also, I was told to make sure that the roots are not rotten. My plant is truly pathetic looking right now. Here is a pic. http://haneedesigns.net/tempics/begonia.jpg Best to you |
