Answer: The answer to your question may include several factors. Roses need full sun (at least six hours including noon) to bloom well, as well as rich soil that is evenly moist yet well drained. Hybrid tea roses would be trimmed back hard (although not quite to the ground) each spring as you described, because they bloom on new growth of the season. Many other types of roses, however, bloom only on old wood from previous growth. I suspect you may have one of these roses and the pruning has been removing the blooming wood. You might try skipping all pruning except to remove dead or diseased branches and see if you get blooms next year.
