Hi!

I received this Begonia (I believe it's a Begonia Corallina but correct me if mistaken) from a friend which belonged to her mother.

The plant is gorgeous, I hope it enjoys its new home. My question is regarding how big it is. I want it to be healthy and I was wondering if I should trim it or just let it be. Also I saw the roots are getting out of the pot from the bottom so I am also wondering if it needs repoting, and if so, maybe after it has adapted or after spring/summer?

Also, if I don't need to trim it, do you think I should help it stay upright with a stake? It doesn't support by itself (in the picture is against the wall and that is how it has been before apparently).

Please let me know your opinion on this matter.

In a nut shell, trim or not to trim? And how to trim it if needed? And repot or not repot?

Thanks a lot😊😊

Welcome! In a nutshell, prune it and don't repot it.

Cane type Begonias grow upright and get taller and taller unless they are pruned back regularly. As individual stems get taller, they also lose older lower leaves so they become quite leggy looking. You can prop yours up with ever taller stakes if you want, but I think pruning it is a better option.

I suggest you start by pruning back the tallest stem or cane to a node about 4-6 inches above the soil. New leaf growth will emerge on the node just below where you make the pruning cut. That is true for all of the stems that you will want to prune back at some point. Pruning will shorten the plant and promote new leaf growth lower down. It does not harm the plant in any way.

Tip cuttings with 3 or 4 leaves and a short stem can be propagated in water or in a small pot with a porous potting mix.

I agree. I like them short and full rather than tall and leggy.

The tips cuttings with only one or two leaves, and then a couple nodes, can be potted right away. They root easily and the nodes below surface will send up new stems alongside the cuttings..
i'm pretty OK today, how are you? ;^)
