Wondering why my Barbados Cherry has sprouted any flowers it’s doing fantastic. Has grown a lot in the past month when I first got it when it all those leaves are falling off every part of that, but no flowers no cherries.
Also, I have a pink power puff I had lost all of its leaves and I was wondering if it’s from overwatering and starting to now grow tiny little leaves once again just curious and I also had a maple leaf I believe I had bad sunburn, so do I just put it in the shade?

If the tree is kept in the spot where photo is taken, it may not flower because lack of light.

Flowering in all trees is triggered by environmental factors. Indoors it may just get the right conditions?

The tree look very young. Many flowering trees must mature several years before first flowering.

Just some ideas you can take into consideration when experimenting to get flowers.

It sits on the windowsill

Excactly. In most homes the conditions on a Windows is stable all the time. Most plants trigger blooms because of natural fluctrations in environment. That is how they flower on the excact time if the year, every year. And that is when it is absolutely most beneficial to them. No fluctations, no flowers.

There are a two exceptions. Some plants flowers after a period of draught. That can be simulated indoors. Some triggers by longer or shorter days in spring or authum. If your area have approx the same yeary sun cycle as the plants natural environment they can bloom indoors as well.
