Floribunda roses grow a cluster of blooms at the end of lateral branches which grow out from the main canes. The more you prune your floribunda, the more blooms it will produce later in the summer. The best time to prune floribunda roses is in late winter or early spring, before the plant begins active growth for the season.
Remove any canes that are dead or diseased looking.
Prune out any canes that are growing across another one. Choose between the two crossing canes, keeping the one that is growing toward the outside of the bush.
Cut out any other canes that are growing toward the interior of the plant.
Remove canes that are smaller in diameter than a pencil.
Cut back all remaining canes by one-third of their length.
