Recently I did some work on a Illawarra Flame Tree.
This was a good stub left by previous person, in fact there were lots of stubs like this I fixed up.
Note that to expose the callus tissue I had to rub off the old dead ugly bark.
Notice in this example not a lot gained, and notice the angle of growing. Now if the cut would have been made to resemble that callus growth it would have been better and not left a homing beacon for borers etc.
Now ironically that callus roll and the whole angle thing going on there resembles the target cut that is prescribed here according to our standards.
