Own-root hybrid tea roses – care – PharmaRosa®

Hybrid tea: large flowers, clear pruning logic

Would you like a hybrid tea rose with large, elegant flowers, but want to avoid pruning mistakes? Here we briefly show the ideal planting distance, the extent of spring pruning, the logic of pruning between flushes, as well as irrigation and feeding timings. Special attention is given to ventilation and prevention so that the foliage remains attractive. What is your goal: cut flowers, bed display, or both?

Quick principles

  • Site: sunny, airy position; foliage should dry quickly.
  • Spacing: generally 45–60 cm in beds (depending on planting density).
  • Pruning: from year 2 you can cut back ½–⅔ of shoot length; prune to an outward-facing bud.
  • Watering: less often but generously; 10–15 L per time for established plants.
  • Nutrients: CRF in spring + top-up after heavy flush; avoid N after mid-August.

Position & spacing

Setting Recommendation Note
Private garden (bed) 45–60 cm spacing Uniform line, easier pruning and care
Container / terrace Pot min. 10–15 L Loose, airy medium; good drainage
Public and green spaces 45–60 cm spacing 6–10 cm long-lasting mulch; automated irrigation is an advantage

Pruning – hybrid tea

  • Year 1: health pruning only (damaged, crossing parts).
  • From year 2: generally cut back ½–⅔ of shoot length; 0.5–1 cm above an outward-facing bud at 30–45°.
  • In season: regularly remove spent blooms to encourage new flushes.

Jump to watering →

Watering

  • Established plant (in ground): 10–15 L per time, once a week; in heatwaves twice a week.
  • Container: 2–5 L every 2–4 days, more often in heatwaves; do not let water stand in the saucer.
  • Timing: morning; avoid wetting the foliage.

Details: Watering.

Jump to nutrients →

Nutrients

  • Starter feed: CRF in spring (3–4 months) mixed/incorporated into the soil.
  • After flowering: top up with CRF or liquid rose fertiliser.
  • Late summer: K-focused; avoid N after mid-August.

Indicative rates: CRFliquid.

Jump to plant protection →

Plant protection

  • Prevention: airy bush shape, morning watering at soil level, 5–8 cm mulch, good hygiene.
  • Susceptibility: powdery mildew/black spot – especially in shade; monitor and act in time.
  • Starting point: gentle products (potassium soap/white oil, biological products), rotate if needed.

Guide: Plant protection.

Jump to timing →

Timing (key points)

  • Spring: early spring pruning; starter feed from bud swelling.
  • Summer: heatwave watering, cutting back spent blooms.
  • Autumn: planting bare-root; stop N, top up mulch.
  • Winter: check crown protection; in pots, occasional watering in a frost-free window.
