When is the best time to prune knock out roses?

I always do it in February with great success. I am in zone 7b.

Zone 6 is late Nov, early Dec

Early spring …..April-ish.

When the forsythia is blooming.

Hi Angela, I don't know about knock out roses as I have never heard of them before, but I prune my roses either Early Spring or after flowering. (sometimes both)

Late winter to early spring. I am in zone 9 and prune in late January to early February and have my first blooms by Easter. These sites will help you.

Prune late winter (mid to late Feb.or very early Mar. in zone 6.).

Hi Angela - This is a great article on rose trimming that's also loaded with a big dose of inspiration. Hope this helps! Hugs, Holly
