After planting my begonias months ago they are starting t actively grow. A few weeks ago I lightly dug into the potting mix to check to see if they are alive. Even though I was gentle I did break a few small growths. Most tubers had more than one shoot, two of those I broke did not have more than one. Will the tuber shoot another stem or did I kill it?

If they are healthy, they will produce more sprouts. If they are spent, dried out etc they may not.

My begonia is not growing at all! It's been months and she is unchanged. Anyone knows why? Fertilized it (7-3-5) once since I got it. And water it when the soil is almost dry. Humidity levels usually are above 60%.
