Hi! annapie, welcome to Gardening & Plants :)
Borrowed from:
Rose Propagation by Dr. William C. Welch
When to take the cuttings:
Roses may be rooted at any time of the year, but for home gardeners, success is much more likely during the cool months from November through February. Late fall is a favorite time because there are usually a few blossoms still remaining on everblooming types to identify them.

So, if your North of the Equator, now is good. South You may have better success if you wait till June.
