I planted a climbing rose against my front porch. It has grown profusely but has never bloomed. The other roses in that same area have bloomed wonderfully all summer.
How and when you prune your roses can impact flowering. Many climbers bloom on old wood. Pruning them back in fall, winter or spring before they bloom eliminates the flowers for the following summer. Remove only the dead canes back to ground level next spring. Wait and see if this corrects the problem. Some climbing roses are grafted onto a hardy rootstock. If the winter kills the grafted portion the hardy rootstock will take over. It tends to produce stout canes with more thorns and few, if any flowers. In this case replace the climber with a new plant.
