Thanks Zuzu! I'll follow your suggestion & cut the top third of the canes. Some of them are bending, in fact one is laying on the ground, and I don't want the plant to be stressed trying to support those long canes.
I'll be pruning the rest of my roses, this week or next, after I attend a local nursery's rose pruning workshop. I've pruned my few hybrid teas, in the past, but am new to shrub roses.
We usually don't get much rain, but my garden (& I) is/are loving the water this year.
Thanks again!
Liz
