Field production NEONATAL: 17–18 months, drip irrigation & IPM – PharmaRosa®

D) Field production (SOP – 17–18 months)

Operational discipline, block-based logic, IPM – consistent large batches

Field production is for those who wish to grow own-root roses in a commercial set-up, over a longer cycle and with structured block management. The key factors are: good site selection, drainage, drip irrigation, a weed-free root zone, and disciplined, phase-based management of water–nutrition–IPM.

In brief – field route in 10 points

  • Site: good air movement, quickly drying surface, good drainage (avoid humidity traps).
  • Soil preparation: removal of compacted layers (subsoiling), raised beds recommended on heavy soils.
  • Drip: practically essential (even establishment + faster leaf drying).
  • Timing: frost-free period + workable soil (not waterlogged, not smearing).
  • Planting depth: top of the plug 2–3 cm below soil level; do not bury green tissue.
  • Watering-in: thorough immediately after planting; even moisture for the first 4–6 weeks, without standing water.
  • Spacing: according to target (fast homogeneous vs more open, robust stands) – with row/plant distance options.
  • Nutrition: phased logic, moderate N at start, monitor K ratio; soil analysis is fundamental.
  • IPM: weekly inspection, hotspot marking, records; cultural measures first, chemistry second.
  • Lifting: close to dormancy, with rapid root protection and uniform packing.

PharmaRosa® NEONATAL – tray-rooted rose plug plants for further professional production

D1) Block and soil preparation

1) Site selection – “rose-friendly” minimum

  • Good air movement, avoid humidity traps (valley bottoms).
  • Quickly drying soil surface (reduced risk of foliar diseases and root-zone problems).
  • Drainage: roses do not tolerate an airless root zone.

2) Soil cultivation – nursery block logic

  • Basic autumn tillage where possible: loosening/subsoiling to remove compacted layers.
  • Spring bed preparation: fine tilth but not dusty; should not puddle under irrigation.
  • Raised beds are recommended on heavy soils (better drainage, faster warming).

3) Infrastructure

  • Drip irrigation: a key factor (even start, faster leaf drying, fewer foliar diseases).

D2) Timing of planting out (frost-free period) – decision rules

Field decision tree

  1. Risk of night frost? If yes: wait, or be ready with crop cover (fleece/row cover).
  2. Is the soil workable? If it smears or is waterlogged: do not plant (compaction = airless root zone).
  3. Drying wind + sun? Start-up irrigation is essential for success.

Reception operations: do not leave propagation material unprocessed for days; only short-term storage in cool, bright conditions.


D3) Field planting procedure (step by step)

1) Handling tray material

  • NEONATAL: 1 variety / tray, 10 plants/tray – worth linking this to the block plan in advance.
  • Before planting the plug should be moist throughout, but not waterlogged.

2) Planting depth

  • The top of the plug should be placed 2–3 cm below soil level.
  • Do not bury any green tissue.
  • Target: stable anchoring, reduced desiccation stress, better basal shoot formation.

3) Watering-in

  • Thorough watering immediately after planting.
  • First 4–6 weeks: even moisture (without standing water).
  • Later: less frequent, higher volumes (to encourage deeper rooting).

D4) Spacing, row and plant distance options + plant form

A) For bare-root lifting (mechanisable nursery block)

  • Row spacing: 1.0–1.2 m
  • In-row spacing: 0.25–0.40 m
Example spacing Indicative plant density/ha
1.0 × 0.25 m ~40,000 plants/ha
1.0 × 0.30 m ~33,300 plants/ha
1.2 × 0.40 m ~20,800 plants/ha

B) For more robust, airier stands (more IPM-friendly)

  • Row spacing: 1.2–1.5 m
  • In-row spacing: 0.40–0.60 m
  • Example: 1.5 × 0.50 m → ~13,300 plants/ha

Plant form regulation (uniform bush)

  • After establishment, create a uniform “starting level” using guideline heights and batch discipline.
  • Manage dominance: avoid single “shooting” stems that increase variability.

D5) Irrigation and fertilisation (by growth phase)

1) Irrigation – establishment (first 4–6 weeks after planting)

  • Target: rapid plug–soil contact.
  • The plug must not dry out, but there must be no standing water (oxygen in the root zone!).

2) Irrigation – bulk growing

  • Less frequent, higher-volume applications (towards deeper roots).
  • Avoid wetting foliage (drip irrigation is an advantage).

3) Nutrition – structure, not kg/ha dogma

  • Start-up: moderate N (too much N = soft tissue + more foliar disease).
  • Intensive phase: split N applications; monitor K proportion (tissue firmness, stress tolerance).
  • Hardening: reduce N, emphasise K.
  • Soil analysis: the basis of any precise programme (especially P, K, micronutrients).

Weed control: a weed-free root zone is often worth more than “+20% fertiliser”.


D6) IPM – field operations

Prevention (your strongest tool)

  • Open spacing → fast leaf drying.
  • Drip irrigation → foliage remains dry.
  • Weed-free stands → better air movement, fewer “bridge” host plants.
  • N discipline → avoid overly “soft” crops.

Monitoring – minimum protocol

  • One fixed inspection per week (field edges + inner transects).
  • Hotspot marking (stake/tape) + revisits.
  • Records: date–variety–block–symptom–weather–intervention.

Intervention – “cultural first, then chemistry”

  • First improve microclimate and irrigation rhythm.
  • Use targeted treatments only when justified, with product rotation.

D7) Lifting / preparation for despatch

Bare-root lifting

  • Timing: close to dormancy (after leaf fall in autumn or early spring).
  • Soil condition: neither mud nor concrete – for workability and root protection.
  • Rapid root protection: immediate protection against drying-out.
  • Grading: uniform packing and batch-specific handling.

Common mistakes (and fast correction)

  • Standing water / airless soil: lack of drainage → raised beds, loosening, irrigation fine-tuning.
  • Weed competition: root zone not clean → critical in the first 2–3 years.
  • Excess N: soft tissue → reduce N, emphasise K, lower IPM risk.
  • Lack of monitoring: hotspots get out of hand → weekly inspection + hotspot marking + records.

Why is the field route an advantage for the buyer/producer?

  • Operational discipline: large volumes, predictable process with block-based logic.
  • IPM-friendly: spacing + drip + weed discipline → fewer emergency treatments.
  • Own-root advantage: no budding/grafting risk, simpler plant architecture, more stable regeneration.
