Hello!

I am interested in advise about growing a rambler into a tree. I have a
treed-up ligustrum, about 14 feet high, and would like to plant a rambler,
specifically, an Albéric Barbier, to grow up into it. How far away from the
trunk should the rose be planted? How do I train it before it reaches the
first branches?

(I'm in zone 9 if this is helpful.)

Thanks so much!
