Rambling roses and climbers have the same basic needs for blooming as rose bushes. With only a few minor differences, the rules for growing a climbing rose are the same as the 10 steps for growing bushes. Here are the steps that are different.
7. It was not pruned properly — Ramblers and climbers have special pruning needs, and can fail to climb if pruned incorrectly.
11. It was over pruned – Many climbers must reach a certain height before they can produce blooms. Some climbers will stop blooming all together if they are pruned too zealously.
12. It was not given proper support –Climbers must have something to climb on or cling to, such as a post, a wall, or a trellis. Also, some climbers must be tied to the support until they are trained to climb, or they will drag to the ground.
