|I received an Angel wing begonia from a professor, and it has been thriving! It's by a west-facing sliding door and has been doing exceptionally well. However, I did not anticipate it getting this large. I think it needs a bigger pot, but how do I determine when to repot, and what size of pot? The plant is currently almost 3 feet tall. Thanks in advance

|Terrific looking Angelwing Begonia. It needs to be pruned. It does not need a larger pot.
New growth is always at the ENDS of each stem so the stems keep getting taller and taller. Eventually, gravity starts to pull them over as is happening with one of your stems already. In addition, as the stems get longer, lower leaves will naturally die back. If left unpruned, you will end up with tall, bending bare stems with foliage and flowers only at the top ends. It is best to prune long before that happens. Pruning will produce a short, fuller, more compact plant.
Any stem can be pruned above any stem node. New growth will then emerge from that node and grow upward from there, so be sure to cut back the stems pretty far. The top cuttings can be rooted in water or damp soil.
Your Angelwing will need a larger pot only when there is no longer enough soil to retain water for at least three days. That is not likely to happen for the foreseeable future.
Move your plant closer to the window if possible.
