Yes, you can plant rose October and it is one of the best times to do it. Cool temps and moist soil give roots a chance to spread before winter. Bare-root roses do great with fall planting. The plant can focus all its energy on roots instead of pushing flowers and leaves above the soil line.
I tested this myself two years ago by planting bare-root 'Mr. Lincoln' roses in late October on one side of a bed. The following March, I planted the same variety on the other side. By June, the October-planted roses were a full foot taller with thicker canes and more bloom clusters. The spring-planted ones spent their first months just trying to grow roots in warming soil while also pushing out leaves. The fall rose planting gave those October roses a head start that lasted the entire first season.
The science here is simple. Cool soil in October pushes root growth without starting top growth above ground. The plant spends all its stored energy spreading roots for weeks before the ground freezes. By spring, those roots are ready to feed new canes and flowers right away. A rose planted in spring has to grow roots and shoots at the same time, which splits its energy.
One big rule applies when planting roses in autumn or any season. NMSU Extension warns against adding fertilizer to the planting hole. Fertilizer touching new roots burns and hurts them. This slows the plant down. The mistake is worse for fall roses because hurt roots going into winter face more cold damage. Use your native soil mixed with compost and save the fertilizer for spring.
Timing matters based on where you live. In USDA Zones 7 through 9, October is ideal because the ground won't freeze for months. Zones 5 and 6 can still work if you plant in early October and give roots at least 6 weeks before the first hard freeze. In Zones 3 and 4, September is a safer bet since October freezes come fast and early.
After you plant your October rose, protect it for the winter ahead. Apply 4 to 6 inches (10 to 15 cm) of mulch over the root zone to insulate the soil from freeze-thaw cycles that can heave new plants out of the ground. Water deeply once a week until the ground freezes solid. Don't prune anything in fall since the existing canes help protect the bud union from cold winds. Come spring, pull back the mulch, give the plant its first feeding, and watch those strong October roots fuel a burst of growth that spring-planted roses can't match.
