I have an arbor on which I plan to train two Renae (climbing floribunda or polyantha) roses a la Paul Zimmerman in his wonderful YouTube tutorial. One rose on each side of the arbor. About six months ago I planted a Snowbelt (polyantha shrub) about two feet from the arbor (why? I wasn't thinking!) If I plant Renae at the foot of the arbor, she will be about 18 inches from Snowbelt. Too close? Snowbelt has been very vigorous in the ground. Renae has been very vigorous in pots.

Any thoughts such as "no way, dimwit!" or, preferably, "no problem!" would be very much appreciated.
