Pruning own-root roses – guide – PharmaRosa®

Pruning: less cutting, more renewal

When pruning own-root roses, the aim is not to “cut back hard”, but to keep the bush airy and preserve the renewing shoots. Here we show what to do in the first year, how to shape from year 2, which cutting techniques are safe, and how the pruning of hybrid tea, floribunda, shrub, climber or groundcover roses differs. Have you been pruning too much or too little and feel unsure now?

Timing

• Main spring pruning: before buds swell/break (late winter–early spring), on a dry, frost-free day.
• Summer maintenance: cutting back spent blooms/shoot tips to encourage repeat flowering (on repeat-blooming varieties).
• Once-flowering roses: shaping cuts should be done after flowering (flower buds are borne on the previous year’s growth).
• Autumn: only light tidying and preparation for winter protection; do not carry out heavy pruning now.

First year (own-root)

• Health pruning only: remove damaged, diseased, prostrate and strongly crossing parts; do not cut the plant back completely.
• Keep strong basal shoots (emerging from the crown) – these form next year’s framework; on own roots, suckers are valuable renewal growth.
• In summer, cutting back spent blooms stimulates further flowering (once-flowering roses are exceptions – see below).

Basic steps (technique)

• Direction of cut: 0.5–1 cm above an outward-facing bud at a 30–45° angle.
• Crossing shoots: remove them from the centre of the plant → better air movement; very thin shoots (thinner than a pencil) should be removed at the base.
• Old, weak, diseased growth: thin out gradually over several years; a rejuvenating cut can be inserted every 3–4 years.
• Tools and hygiene: sharp, disinfected secateurs; use loppers/saw for thicker parts. After pruning, collect fallen leaves.

After pruning we recommend: deep watering and moderate feeding to get growth started; in late summer, extra potassium helps ripen the tissues.

Private garden

• Light shaping: up to about one-third of the shoot length can be removed to encourage branching; keep the centre of the bush open with framework stems growing outwards.
• In beds, aim for an even canopy height for a harmonious overall look; keeping 6–9 strong framework stems gives a balanced structure.
• Spring opening steps: cut back frost damage and dry shoot tips to healthy tissue; remove inner, crossing stems; shorten remaining shoots to an outward-facing bud.
• According to vigour: prune weak shoots harder (shorter), strong ones more lightly – this results in an even, balanced bush.
• Height and layering: in front gardens/beds keep the front low (35–45 cm), the middle medium height (50–70 cm), and the back higher (70–100 cm) – this gives a tidy, easy-to-read composition.
• Rejuvenating thinning: every 3–4 years remove 1–2 of the oldest, woody framework stems at the base to make room for new basal shoots; it is worth spreading this work over several stages and years.
• Summer shaping: between main flowering flushes, cut back spent blooms to the first strong, five-leaflet leaf; in hot spells, pinching back the tips by 1–2 leaves helps keep the bush compact.
• For hips or for display: if you want decorative hips, do not deadhead after the last autumn flush; but for continuous flowering, regular deadheading is the priority.
• Fine-tuning to microclimate: in exposed, frost-prone spots, prune more lightly; in sheltered, warmer positions, stronger pruning is acceptable.
• Managing self-renewal: on own roots, new strong shoots from the base are valuable; if too many appear and cause congestion, thin out the weakest at the base and keep the stronger ones as framework.
• Safety and use: do not leave thorny shoots sticking out along paths; lightly trim any shoots overhanging pavements straight away.
• Staking and support: in very windy spots, tie in long, whipping shoots – this reduces damage and the number of pruning wounds.
• Aftercare: after more severe cutting back, deep watering and moderate feeding are recommended so the plant closes wounds quickly and makes balanced new growth.

Pots / terrace

• Foliage volume should match the pot size (to avoid rapid drying out); in the first year, health pruning only, from year 2 shape according to type.
• Regular deadheading on repeat-bloomers; on mini/patio types, prune back by 1/3–1/2 in spring for a compact shape.
• Canopy–pot ratio: as a general rule, the canopy diameter should be at most about 1.5× the pot diameter, and plant height should not be consistently more than 2× the pot height – this helps prevent water stress and toppling.
• Structural spring pruning: after removing frozen and damaged parts, shorten strong shoots moderately and weak shoots more; the goal is a stable, compact canopy that dries out less quickly in the wind.
• Summer fine-tuning: during heatwaves, shorten overly long, water-demanding shoot tips by 1–2 buds; pinching back “blind” (non-flowering) shoots triggers new branching and buds.
• Autumn–winter care: in autumn, only light tidying; before winter, slightly shorten the longest, whip-like shoots so they are not torn by the wind – leave main shaping for spring.
• Tying and securing: on balconies/terraces, use supports (trellis, cane) for longer shoots because of draughts; for climbers, fan out the framework stems and shorten side shoots in spring.
• Repotting and root pruning: repot with fresh compost every 2–3 years; at this time you can trim back the outer root zone by 10–20% and adjust the top growth to match – a balanced root–shoot ratio supports faster recovery.
• Balancing the load: after repotting or stronger spring pruning, allow fewer buds to develop in the first flush; once strength returns, gradually allow more flowers.
• Shade vs. full sun: in full sun, transpiration is higher, so keep the canopy more compact; in partial shade it can stay looser, with longer shoots.

Positioning: Pots / terrace.

Public and green spaces

• In-season trimming to maintain traffic and visibility safety; keep a uniform height/plane for “carpet-like” surfaces in groundcover plantings.
• Clean, uniform edging of groundcovers for a tidy look; in very dense patches, remove a few older, woody stems at the base to improve airiness.
• Safety zones: cut back any branches overhanging pavements, roads or driveways immediately; at junctions, keep the visibility triangle clear according to local regulations.
• Mowing/pruning schedule: on large areas, supplement the structural spring pruning with 2–6 in-season hedge trims (depending on climate and growth vigour).
• Degree of cutting back: on mass plantings, remove at most one-third to one-half of the current year’s growth at a time so the plants close up quickly and the surface does not become bare.
• Differentiated treatment: edges, corners and traffic nodes need precise hand finishing (secateurs after the hedge cutter) so that the margin remains “clean”, without ragged ends.
• Block-by-block rejuvenation: on large plantings, carry out stronger thinning/renewal on 20–30% of the area each year so the whole surface remains young on a 3–5-year cycle.
• Preventing damage and litter: use sharp blades for mechanical trimming; torn, shredded surfaces heal slowly and become entry points for disease. Collect green waste immediately after cutting.
• Intensity of use: next to playgrounds, schools and institutions, prune thorny growth further back from paths; tie or remove any leaning shoots at the base.
• Climbers and fences: on fences or pergolas, fix framework stems as close to horizontal as possible, and shorten side shoots to 8–10 cm each spring – this produces an even band of bloom.

Group-specific guidelines

Hybrid tea

• In the 2nd spring, shorten stems by about 1/2–2/3; prune weak stems harder, strong stems less.
• Keep 4–7 strong framework stems; remove very thin shoots at the base; always cut to an outward-facing bud.
• During the season, deadhead regularly; from the 2nd year you can cut for vase with 15–20 cm stem length.

Floribunda / bedding

• In the 2nd spring, cut back by about 1/3–1/2; the aim is a bushy, free-flowering plant with several, well-spaced medium-strong shoots.
• In summer, light pruning between flowering waves; remove overly thin shoots at the base to keep the crown airy.

Shrub / English

• Light shaping: maintain the natural bush form, thin out inside; cut back about one-third of the bush, leaving about two-thirds of the height.
• Rejuvenation every 3–4 years: remove 1–2 of the oldest, woody stems at the base to make way for new basal shoots.

Climbing / rambling

• Year 1: do not prune; grow several strong, long shoots and tie them in (trellis, pergola, wires – angled at 30–45° or almost horizontal).
• From year 2: keep the selected framework stems; in early spring shorten side shoots on these to 8–10 cm (just above an outward-facing bud, at an angle).
• Repeat side-shoot pruning every year; thin if overcrowded. Rejuvenate framework stems every 3–5 years by bringing in new basal shoots.

Groundcovers

• Once-yearly shaping cut (usually 10–15 cm) for a neat, even surface; “carpet-style” trimming with hedge trimmers or secateurs.
• Recommended level: cut back about one-third of the shoot length; at most by half, otherwise the surface may open up in patches. Keep edges clean.

Mini / patio

• Regular deadheading; in spring, prune back by 1/3–1/2 for a compact shape.

Once-flowering roses (old shrub roses, ramblers)

• Rule: always prune after flowering (flower buds are borne on the previous year’s shoots).
• Cut back flowered stems to 8–10 cm; thin out old growth to encourage renewal; train in new long shoots from below (for later framework replacement).
• Ramblers: need a sturdy support; long stems bent into arches produce more flowering side shoots; avoid hard winter pruning.

Common mistakes

• Cutting back too hard on own-root plants → unnecessarily slow start; can result in soft, weak new growth.
• Leaving inner, crossing stems → poor air movement, higher disease risk; leaving shoots thinner than a pencil leads to overcrowding.
• Hard spring pruning of once-flowering roses → loss of most of the flowering flush (always shape after flowering).
• Cutting off suckers on own-root plants → blocking natural renewal (these are valuable shoots).
• Cutting too far above a bud → dead stubs; cutting too close → bud damage. Heavy late-autumn pruning → risk of winter dieback.

After pruning: deep watering, tool disinfection, and plant health inspection.

Required tools

• Secateurs
• Loppers / saw
• Disinfectant
• Gloves
• Tying material (for climbers)

Sharpen and disinfect before each work session; early spring spray (oil, copper/sulphur according to the label) can reduce infection pressure.
