Cane begonia won't bloom

What I am doing wrong? I don't water it until the first two inches of soil are dry. I mist it a couple times a day. I kept in in an area where it gets indirect light. I moved into my new house a couple months ago, so it has been getting more light (as pictured), but I make sure it doesn't get hot.

The first year we had the plant it started out as a strange stick some lady from craigslist gave us. We kept it in a east facing window at that apartment and it bloomed profusely the second year. At this point we had no idea what this thing was (or why it looked like an angry centipede with scythe legs) and didn't give it any special attention. Then I figured out what it was and the thing decided to stop playing nice. I know begonias aren't always the easiest, but now I feel like I have been challenged by this strange red/green menace (that I love immensely) and I will not stop until I win this little game. Please help me. :)

Side notes: All the stems are less than 3 years old, most are less than 9 months. The plant was severely damaged during a move and the pieces were used to grow new stems. The middle stalk is the newest natural stem (3 months old). It is quite thick compared to the others and has smaller leaves. There is another basal sprout coming up and one of the stems is growing a side shoot.

For one thing, I think it gets too much light. Look at the leaves, they are faded out. Too much light. Move it.

If it were mine, I would break all of those long canes off in half, and take a couple leaves off the bottom of each, and stick them in the ground with the rest. OH, BTW, how long since it has had new soil or mix? If not long, good. Then I would give it a weak fertilizer and some peroxide in the water. And then leave it alone.

One more thing, where you cut/break the canes off, cut the stalks down to the top of the leaf.

All of this is my opinion. You might be watering it too much too.

I have tons of those because I break the canes off when they get tall and root the pieces. Mine stay outside in dappled shade all year except for Dec and Jan. Ive never misted mine. We have plenty of humidity here. Mine bloom constantly. The stems on yours are thin compared to mine. That and lack of blooms tell me you need more light not less. Put it outside for the summer and in that pot, water every two weeks unless it rains. I would cut back all those tall canes and fertilize with MG blue water. You will get blooms and large glossy dark green leaves. Outside, no need to mist which might be causing the leaves to look pale.

Give it some fertilizer and more light, not less to get it to bloom. Some canes (like Sophie Cecile and Cracklin' Rosie) are "shy" bloomers and most folks will never get those to bloom but only in Florida and California with year round light and warmth, can they be coaxed to bloom. Yours looks like 'Corallina de Lucerna' which is a very old hybrid and passed around to almost everyone. You shouldn't have to mist it either. It will bloom but is not the easiest of canes to bloom. If you want a cane begonia that blooms easily try 'Lana', 'My Special Angel', 'Irene Nuss', coccinea, and many other good old standbys.

Thanks!

hcmcdole what is that smaller purple leaved begonia growing between the two larger pots?

That would be 'Maurice Amey'. Wonderful grower in summer, terrible in winter due to being a mildew magnet. It is one the "Mallet" type begonias with a Philippine parent (U060 something) and they all exhibit this trait - love the heat but in cool weather they quickly become sickly with mildew outbreaks.

Here is a close up of it and another mallet - 'Don Miller'.
