Some climbing roses bloom only on second-year stems. A complete lack of bloom on your climbing rose makes me suspect you are losing or removing the stems before they reach blooming age. If you live in a cold climate, you may need to remove the climber from its trellis over the winter. Lay the stems down, cover them with soil, and mulch them to permit them to survive the winter and bloom the following year. Also, avoid early-season pruning of climbing roses that normally develop just one flush of bloom, except for removal of weak or diseased canes and canes that have already bloomed. Pruning out strong, healthy first-year canes means you're removing next year's potential blooms on these varieties.
