I had spend a lot of time thinking hoh to grow a side branche on a main branch on my azalea
I came up with a nice special technicque.
First I removed all the leves from the chosen little branch.
And masured its thickness.
Then I drilled a hole into the main branch.
And after that I guess you know how it goes.
A bit of cut paste.
And some wire for suport.
I hope it will grow nicely. We'll see next year.
