How to prune historical roses (once-blooming): complete guide

Why do you prune historical roses differently?

Historical roses (also called old roses, heritage roses, heirloom roses) form their flower buds before winter. They typically bloom only once per season - often in May or June - unlike modern hybrid roses that bloom for months. This means your pruning timing and technique are completely different.

If you prune a historical rose at the same time as you prune hybrid tea roses, you remove next year's flower buds. You get a beautiful plant with few blooms. That is why timing and gentleness matter for these old beauties.

Classical cultivars like Rosa 'Madame Isaac Pereire', 'Souvenir de la Malmaison', 'Cardinal de Richelieu', and 'Gertrude Jekyll' grow slowly, form themselves into large arches and shrubs, and deserve respect for their natural shape.

Types of historical roses

Historical roses fall into groups that each have their own pruning preferences:

Gallicas (Rosa gallica) are compact shrubs that stay relatively small. They shape themselves almost naturally, bloom heavily in June, and need minimal pruning.

Damasks (Damascene) are larger, often looser, bloom abundantly heavy. They can use some structure guidance.

Centifolias ("hundred-petal roses") grow large with heavy blooming branches. Those branches bow under their own weight. They carry their beauty with grace.

Albas are cold-hardy, grow tall, bloom elegantly with fragrant single or double flowers.

Bourbons can be repeat-bloomers (not all). They grow vigorously and form long canes.

When do you prune historical roses?

This is the key: right after bloom, not in spring.

Historical roses build their flower buds in summer and autumn. So:

• Pruning time: May-June, immediately after bloom fades. Do not wait until July. The sooner after bloom, the more time for bud formation in summer.
• No spring pruning: March pruning will remove this season's blooms.
• No autumn pruning: October pruning damages future buds.

Only one pruning window per year - after bloom.

Step-by-step

Step 1: Remove dead wood

Right after bloom, examine your plant. Remove dead, diseased, or crossing wood down to the ground. This initial cleanup makes the plant clear.

Step 2: Prune spent flowering canes back

This is the core task. Spent blooming canes are cut back to roughly 20-30 cm from where they attach to older wood structure. Do not cut further than this. You want to preserve the old framework.

Practically: Follow each spent cane downward until you find a stronger bud or young leaf. Cut just above it.

Step 3: Thin, do not shape

Historical roses love their natural, loose form. You do not cut them into balls. You thin out the canes so sun and air can flow through. Remove only canes that:

• Grow over other canes
• Grow inward
• Are weak or thin

Step 4: Arching canes stay as they are

This is unique to historical roses. Curved, drooping canes bear far more blooms than upright ones. That arch is intentional. Do not cut to straighten it.

Pruning depth

How much can I cut back?

Gently. Cut spent canes back to 20-30 cm, not to 5 cm. Historical roses heal less easily from drastic cuts. They grow slowly and cannot recover quickly from heavy-handed pruning.

What if I pruned wrong last year?

Patience. Let it grow this year with minimal pruning. Next summer you can gently bring order back. Historical roses take years to recover from a wrong cut.

Why do I see few blooms?

Most likely: you pruned in the previous spring. Your plant grows leafy but does not bloom. Next year: do not prune until after bloom.

Frequently asked questions

Must I thin historical roses after bloom?

Yes, but minimally. Remove only dead wood and crossing canes. Keep the natural form intact.

How large can historical roses grow?

They can reach 2-3 metres high, depending on type. Gallicas stay smaller (1-1.5m), Damasks and Centifolias can grow larger. Let them grow in their natural form unless you deliberately aim for a specific shape.

Can I cut historical roses for a vase while they bloom?

Yes, certainly! This is actually fine. Just cut your blooms while they open. Your plant recovers quickly.

Do historical roses grow in pots?

Yes, but they prefer the ground with space. In pot: minimum 40-litre container, good drainage, regular water.

The secret of old roses

Historical roses are not modern performance roses. They grow gradually, their bloom is brief but spectacular, and their fragrance is often enchanting. They reward patience with years of beauty.

The pruning secret: prune them only after bloom. Let them have their way. Trust their natural form. They look lovelier as they grow larger and wilder.
