I'm looking for some advice on pruning my kaffir lime tree. I live in zone 7a, so the tree is in a container, and I must bring it indoors every winter. I've never been that confident on where to cut when pruning, and maybe as a result, the tree is getting too wide to bring through doorways.

What I would like to do is to cut it back so that the tree will grow more upwards. I'm just not really sure how to go about it, or if it is even possible at this point, so I'm here asking for help. Any suggestions are appreciated.

Here are a few pictures.
















Thanks in advance for your help.

Kaffir lime sparked my interest !
What a history, the word Kaffir has.
The kaffir lime zest, and leaves have many uses.

I'd prune side branches about 25 percent off, for door space.

Good Day and thank you 👍.

What size pot is that? For a dwarf citrus it should be 24 inches.
