Roses don't climb on their own, it is important to know how to train climbing roses.
Roses are often pliable enough to weave through their supporting structures, but to get a good number of flowering shoots from top to bottom I would not recommend it.
Roses tend to bloom upward at the end of their growing tips when they are left alone. They should be trained horizontally with their tips bent downward to make side-shoots grow. This will encourage flower production.
Training climbing roses, we have to differ between once-blooming and repeat-blooming roses.
Once-bloomers are pliable and have the advantage that we can pull them in every direction and position we want to. They flourish heavily and don’t form irritating laterals.
These roses are perfect for rose-arches, pergolas and fences. Trained to them, they will show solid foliage even at the bottom parts of the plants.
Ty the canes in a loose and well-regulated way to get the flower buds at the young shoots well-developed. The young shoots should be fixed properly to the climbing structure. Once it comes to pruning, they can be cut properly without injuring them.
Because of the various kinds of these types of climbing roses, we should respect their growing habit.
Types with vigorous shoot formation should never be attached vertically to their climbing aid to receive blossoms at the bottom parts of a plant. The shoots of these kinds of roses should be trained in a 30-degree fan-shaped way. Thus they will grow at the bottom parts of the plants and bud homogeneous.
Types with moderate growth can as well be attached to vertical supporting structures as pillars or walls. Removing their weak and redundant shoots during their growing period will keep them orderly and maintain their vigor.
I use twine or coconut-twine for sturdy canes, but I like to fix thin and new shoots with gardening clips. They are easy to use and can be readjusted with little effort.
Be ready to follow the canes when they grow up an arch or a tall trellis. You may need a suitable ladder or a stepping stool.
Not every rose has thorns but most of them have and you will be well advised to use rose gloves made from protective materials to avoid injures.
Climbing roses will be a highlight in your garden if they are grown to the suitable climbing aid. Pillars, pergolas, arches and trellises will do a great job to show off their ravishing beauty. Bare walls and fences offer enough space to grow climbing roses.
