I have two cuttings of apple that I intended to graft.  The cuttings have had other ideas.  They've started to push growth and they've callused.  I intend to pot them up and try to root them. 

 

Would rooting hormone on already callused tissue be beneficial or harmful? 

 

I have 1% NAA

1% IBA

8% IBA

 

All in powder form.

 

I haven't had good luck with NAA.  I was thinking of using 1% IBA on one cutting and 8% on the other.  Any experience, knowledge that would contradict this?

 

Thanks in Advance (TIA).  Replies welcome.
