Cutting and rooting (28–42 days)
“Time = quality”: disciplined process, stable hygiene, controlled parameters
PharmaRosa® NEONATAL only provides a stable basis for you if rooting is not a matter of “luck” but a planned, disciplined production process. The essence of the system: controlled mother stock, rapid processing, strict hygiene regime, and controlled climate and time parameters.

In short – what is the essence of NEONATAL rooting?
- Starting point: controlled, continuously inspected mother plant stock.
- Processing: freshly harvested shoots are processed immediately – they are not stored for long.
- Cutting type: single-leaflet, semi-hardwood cuttings – with controlled preparation and sticking.
- Controlled rooting: predefined climate and time parameters (heat, humidity, light, air movement, water/nutrients).
- Indicative timing: rooting typically takes 28–42 days, followed by acclimatisation and crop equalisation.
- Scaling to 1,600 cultivars: enabled by stable hygiene and production control, not a narrow group of “easy-to-root” cultivars.
- Own-root advantage: uniform, own-root starting point → more stable behaviour in your further growing.

Objective & risks
Objective
To produce uniform, healthy cuttings with a stable root system that can be integrated quickly and predictably into your growing technology (polytunnel / cold house / outdoor / field).
Typical risks (mitigated by process discipline)
- Water loss and tissue stress during long storage → therefore: immediate processing.
- Hygiene risk (cross-contamination, Botrytis) → therefore: discipline and disinfection at cultivar level.
- Climate fluctuation → therefore: controlled parameters, stable leaf drying and air movement.
- Variation between cultivars → therefore: standardised production programme and batch management.
Brief technological overview (production logic)
- Mother stock inspection: continuous scouting, discipline at cultivar level.
- Shoot harvesting: under controlled conditions, aiming for minimal stress and rapid processing.
- Hygienic collection and handling: strict tool and surface disinfection by cultivar.
- Processing: single-leaflet, semi-hardwood cuttings; sticking under controlled parameters.
- Controlled rooting: climate and time programme (heat, humidity, light, air movement, water/nutrients).
- Acclimatisation: gradual transition to the growing and shipping environment.
- Crop equalisation: required agronomic operations (pinching, equalisation) to secure a stable starting quality.

Hygiene and cultivar handling – why is this the bottleneck with 1,600 cultivars?
Large-scale, multi-cultivar propagation stands or falls on the stability of the hygiene regime and cultivar-level discipline. The NEONATAL production logic therefore manages cross-contamination risk at system level.
Principles
- Tool and surface disinfection by cultivar – to reduce the risk of cross-contamination.
- Hygienically operated storage units – under controlled environmental conditions.
- Minimal storage time – freshly harvested shoots are processed immediately.
- Batch-based thinking – cultivar × batch × date logic for traceability.
Note: the aim is not to “treat a lot”, but to design the system so that overall risk is lower from the outset.
Climate and time parameters – controlled rooting
Successful rooting does not depend on a single “trick”, but on keeping the parameters stable: temperature, humidity, light, air movement, water and nutrient supply. The aim is to keep the cutting’s water balance and physiological status optimal and to secure even root development.
Indicative duration
- Rooting: on average 28–42 days (depending on cultivar and programme).
- Afterwards: acclimatisation and crop equalisation (to support integration at your site).
Note: rooting time and dynamics depend on the cultivar and programme; stability is provided by controlled, disciplined production.
Acclimatisation – a “good root” alone is not enough
Rooted cuttings go through acclimatisation: we gradually adjust them to the further growing and shipping conditions. The goal is that in your system the plant can be integrated quickly and predictably into your own technology.
- Gradual change: stepwise adjustment of climate and operations to the growing environment.
- Crop equalisation: necessary interventions (e.g. pinching, equalisation) to secure batch uniformity.
- Logistical preparation: supporting despatch quality and transportability.

Typical mistakes – useful to know also on your side
1) “Let it stand for a few more days” – the most common source of quality loss
Semi-finished material is highly time-sensitive. If it has to wait: keep it in a cool + bright place; dark storage should be avoided.
2) Humid environment with stagnant air
Persistent leaf wetness and poor air exchange build fungal pressure. Best practice: leaf drying plus gentle air exchange.
3) Overly wet, poorly aerated medium
The root zone needs oxygen. Overwatering and “silted” media cause instability.
Particularly useful on your side: Irrigation principles Substrate, pH, EC
Why is the NEONATAL rooting system an advantage for you?
- Stable starting quality: you are not buying “rooting uncertainty”, but a finished, uniform starting material.
- Better planning: the uniform tray system integrates more easily into batch planning and scheduling.
- True-to-type cultivars and batch management: identifiable and traceable even with a large number of cultivars.
- Own-root advantage: no rootstock–scion junction → simpler plant structure, lower technological risk in further growing.
