How to Prune Roses: The Pro’s Guide for South African Gardens

Roses look after you when you look after them. The single most important thing you can do for a rose is prune it properly, at the right time. Get it right and you’ll be rewarded with a stronger bush, healthier growth, and far more blooms come spring. Here’s how the pros do it — no gatekeeping.

When to prune roses in South Africa

Prune in late winter, while the bush is dormant and just before new growth begins. Across most of South Africa that means July into early August. In colder inland areas, wait until the worst frost has passed; on the milder coast you can prune a little earlier.

What you’ll need

Good tools make clean cuts, and clean cuts heal fast. Sharp, quality equipment is the difference between a bush that shrugs off pruning and one that struggles.

• Sharp secateurs — for the clean, precise cuts that do the least damage.
• A pair of loppers — for thicker, woody canes secateurs can’t manage in one pass.
• Thick gauntlet gloves — rose thorns are unforgiving; work with confidence.
• Cloth & disinfectant — wipe blades between bushes so you don’t spread disease.

How to prune roses, step by step

Red shows what to remove. Cut ~5mm above an outward-facing bud, at 45°.

1

Clear the deadwood first. Remove any cane that’s brown, shrivelled or dead. Cut back to healthy green wood.

2

Take out weak & crossing canes. Remove thin, spindly growth and canes rubbing together — rubbing invites disease.

3

Open up the centre. Aim for a vase shape. Good airflow is your best defence against black spot.

4

Cut to an outward-facing bud. The new shoot grows the way the bud faces, so this keeps the bush open.

5

Angle the cut. Roughly 45°, sloping away from the bud, so water runs off instead of rotting the wound.

6

Shorten the main canes. By about a third to a half, to a strong outward bud. Harder pruning = fewer, larger blooms.

After you’ve pruned

Feed and mulch after pruning to power strong spring growth.

Clear away all the clippings and fallen leaves from around the base — they harbour pests and disease over winter. Give the bush a good feed as spring approaches, water it in well, and a layer of mulch will hold moisture and steady the roots. That’s it. The bush will do the rest.
