Growth on tree

[Ivor]

Hello.

I have a small collected Acacia that has had a growth appear about 6 months ago, and from the growth new branches have emerged. You can see this in the photos below.

I was wondering if I have an options to remove it, and the recommended way to do so.

Thank you!

It looks like the tree has been damaged by a wood burrowing insect and then started to heal itself around the damaged area.

You could cut it off but it would leave a scar. The off cut could go into a tray of wet sand with some rooting hormone on it to see if it puts out roots.

I would be inclined to cut it off just to check that thing causing the damage isn't there anymore.

Looks to me like meristematic growth. Cut it off, You can not use it... Your branches look very tender with long internodes. Is your acacia getting enough sun?
