Climbing roses allow you to create dynamic landscapes filled with flowers on walls and arches by training them along structures. The number of blooms and overall appearance change dramatically depending on how you train them. This guide explains training techniques for each type of structure in detail.
Basic Principles of Training
The most important principle in training climbing roses is that "the more horizontal the branches, the more flowers bloom."
Why do horizontal branches produce more flowers? When rose branches grow vertically, apical dominance causes flowers to bloom only at the tip. When branches are laid horizontal or at an angle, flower buds develop evenly from each node, and flowers bloom along the entire branch. The key is to leverage this principle by training branches as horizontally as possible.
Training Timing
Optimal Period: Late December through mid-January The best time to train is when roses have completely shed their leaves and entered dormancy. Without leaves, the branch structure is easier to see, and branches are more flexible and less prone to breaking.
If it's too late After February, buds begin to swell, increasing the risk of damaging them during training. Try to complete training by the end of January.
Training on Arches
Rose arches are placed at garden entrances or along pathways to create a tunnel of flowers.
Choosing an Arch
- Height: 2 meters or taller is ideal. Ensure enough clearance for people to pass through
- Width: 60 cm or wider. Account for the foliage that will develop
- Material: Metal (with rust-preventive coating) offers the best durability
Training Method
- Train 1–2 main canes across one side of the arch
- Guide branches to spiral around the arch in a helical pattern
- Train the opposite side in the same way
- At the top, either cross the branches or drape them to cover the arch
- Tie with natural twine or plastic ties (avoid tying too tightly)
Tips Sharp bends can cause branches to break, so make large curves and gradually change direction.
Training on Fences
Fences are among the best structures for training climbing roses, allowing flowers to spread across a large area.
Training Method
- Spread the main canes in a fan pattern
- Train branches to run horizontal or slightly angled to the fence
- Keep branches 15–20 cm apart to avoid excessive overlap
- Tie at fence intersections for stability
Tips If branches don't reach the top of the fence, don't force them. Stop at their natural length; new canes will grow the following year to cover the upper portion.
Training on Obelisks
Obelisks are cone- to tower-shaped structures that work with potted climbing roses, allowing you to create a three-dimensional flower tower in a small space.
Training Method
- Train branches in a spiral from the bottom of the obelisk
- Tie and secure at each complete rotation
- Arrange branches so they naturally taper as you go up
- At the top, either let branch tips dangle or trim them back
Tips If the obelisk is too narrow, branches will bend at sharp angles, so choose one sized to match your branch thickness. Obelisks 40 cm in diameter or larger are easier to work with.
Training on Walls
This method involves training roses directly on building walls, creating the most dramatic floral display.
Required Equipment Install wires or trellises on the wall to create supports for the branches. Positioning them at least 10 cm away from the wall ensures good air circulation and helps prevent disease.
Precautions Depending on the wall material, moisture can cause damage, so ensure good air circulation. South-facing walls can become excessively hot in summer.
Tying Techniques
- Natural twine degrades over time, reducing the risk of cutting into branches
- Plastic ties are convenient but should be checked regularly to prevent girdling
- Use a figure-eight knot (cross the tie between the branch and support) as the standard method to prevent branches from touching and damaging the support directly
- Ties should be loose enough to allow slight branch movement; avoid binding too tightly
Basic Rose Cultivation Techniques
Training climbing roses is not simply about positioning—it's about creating the location where flowers will bloom.
The more horizontal the branches, the more flowers bloom Roses exhibit strong apical dominance, so vertically growing branches flower only at the tip. When branches are laid nearly horizontal, this dominance is disrupted, new shoots emerge from each node, and the entire branch becomes covered with flowers. This is the primary goal of training.
Train during leaf drop, from December through February While foliage is present, branch condition is hard to assess and the risk of breaking increases. The best time is after leaf drop but before buds begin to swell. Keep long canes that grew the previous year and remove old wood and thin shoots at the base.
Don't bend branches all at once Bending stiff branches sharply causes cracking. Gradually bend them over several days while securing with twine at intervals. For areas at risk of cracking, first check whether cracks already exist near the base.
Use a figure-eight knot for tying Tying branches directly to the support can cause girdling as the branch thickens. Make a figure-eight knot with natural twine to leave space in between.
