I tried to graft 2 this spring and both failed
The smaller one was actually growing roots. So I finally took this failed grafts and rooted both cuttings. Both are doing well.
The only real success here is this little dwarf Pink Singapore that I grafted in 2013, still going strong. The host branch (Hausten white) was cut early this spring and is now well rooted. It is even developing keiki or maybe just leaves on the inflo.
