Fusing Bottlebrush

[Snorlax99]

Any mad scientists out there who have had success fusing a few bottlebrush trees together to make one plant?

I've been gifted 4x lollipops and I have an itch to chop them down and attempt a fusion in a grow box.

I have never needed to fuse bottle brush (assuming you mean Aussie Callistemons?) They usually grow multi trunks without any real provocation and grow fast enough that fusion is not really needed however there is no reason they won't join, especially if you remove the thick bark first.
