Here is a guide and information on pruning climbing roses. We're a UK charity established to share the best in gardening. A properly pruned and trained rose will have blooms from top to bottom.
Before you attempt to prune your climbing rose, you have to be certain that it is a climbing and not a rambling rose type. Yearly attention pays dividends in improved appearance, better flowering, and easier maintenance. A fence made of horizontal metal wires strung tight between posts, as in espalier, is typical. Pruning climbing roses is a little different from pruning other roses.
