The Magic of Climbing Roses
Few plants transform a garden as dramatically as a climbing rose. Trained over an arch, tumbling across a pergola, or pinned against a warm wall, climbing roses add height, romance, and a sense of established permanence that few other plants can match. But growing them well requires understanding how they differ from bush roses — and choosing the right variety for your structure and space.
True Climbers vs. Ramblers: Know the Difference
These two terms are often used interchangeably, but they describe plants with different habits and care needs:
| Feature | Climbing Rose | Rambler Rose |
|---|---|---|
| Flowering | Repeat-flowering (most modern types) | Usually once, in early summer |
| Cane size | Stiff, sturdy canes | Flexible, whippy stems |
| Vigour | Moderate to high | Often very vigorous — can be enormous |
| Best use | Walls, pillars, arches, fences | Large pergolas, trees, wild hedges |
| Pruning | Annual light pruning | After flowering — remove old wood |
Choosing the Right Variety
For Walls and Fences
- 'Zéphirine Drouhin' — thornless, fragrant, deep pink; ideal for narrow spaces and for planting near paths
- 'Climbing Iceberg' — prolific pure white blooms, excellent disease resistance
- 'New Dawn' — pale blush pink, highly fragrant, vigorous; a classic choice for a sunny wall
For Arches and Pergolas
- 'Compassion' — salmon-apricot blooms with outstanding fragrance; manageable size
- 'Generous Gardener' (David Austin) — soft pink, highly fragrant, excellent for elegant structures
- 'Veilchenblau' (rambler) — unusual purple-lilac clusters; nearly thornless
For Cold or Shaded Aspects
- 'Madame Alfred Carrière' — one of the best roses for a north or east-facing wall; white-blush flowers, very fragrant
- 'Dortmund' — single red flowers with a white eye; tough and disease-resistant
How to Plant a Climbing Rose
- Prepare the site — dig a hole at least 45 cm away from a wall or fence, where the soil is less affected by the "rain shadow"
- Angle the plant slightly toward the structure so stems naturally lean toward their support
- Install supports before planting — horizontal wires fixed 30–45 cm apart across a wall, or a sturdy trellis panel
- Plant and water in thoroughly, then mulch well
Training and Tying In
Unlike true climbers (such as clematis or ivy), roses don't grip structures on their own — their thorns simply hook onto things. You'll need to tie stems in regularly. The most important principle: train stems horizontally where possible. When canes grow horizontally, the plant produces flowering side-shoots all along the stem rather than just at the tip. Use soft garden twine and check ties every season to ensure they're not cutting into thickening stems.
Pruning Climbing Roses
For repeat-flowering climbers:
- In winter, remove dead, weak, or damaged wood entirely
- Shorten flowered side-shoots to 2–3 buds
- Gradually replace the oldest main canes with younger growth — aim to have no main cane older than 3–4 years
For once-flowering ramblers, wait until the flowers are finished before pruning, then remove older, flowered canes at the base to make way for new growth.
Common Issues to Watch For
- Poor flowering — often caused by vertical-only training; re-train stems horizontally
- Congested growth — thin out stems regularly to allow airflow and light into the centre
- Black spot on lower leaves — improve air circulation and apply a preventative spray regime
Given the right support and a little annual attention, a climbing rose will be one of the most spectacular and long-lived plants in your garden.
