They die or slow growth in the summer. Examples include pansies, collards, turnips, mustard, snapdragons and winter weeds like chickweed, annual bluegrass, and Florida betony. Many warm season plants are slowing down or going to sleep now. This is what they are created to do. So don't fight it.
Winter is a good time to clean up the rose bed.
Cut out dead, damaged and weak canes, but wait until February to do most of your pruning. Also, remove any limbs that look diseased. Remove old leaves and mulch under plant and discard. Replace with fresh mulch. This will remove much of the blackspot that is in the garden and may lead to healthier roses next year.
