Most explanations of the European requirements are written for the pack house and the exporter. Quite a lot of what they demand, though, is satisfied or lost long before harvest — in the propagation unit, which is where the plant, the medium, the hygiene routine and the first records all begin.

This is what the rules mean where the grafting is done.

What changed, and when

The European Union treats false codling moth (Thaumatotibia leucotreta) as a quarantine pest. Inspection rates on Kenyan rose consignments were raised from 5 % to 25 % from 1 May 2024, which made interception a commercial certainty rather than a risk.

Regulation (EU) 2024/2004 then required a systems approach for roses entering the Union, and it took effect on 26 April 2025. A systems approach means the Union no longer accepts a single control as sufficient; it requires a stack of independent measures that together bring risk to an acceptable level. Kenya’s implementation is coordinated by KEPHIS, and the European Commission’s health and food safety directorate audited Kenya’s phytosanitary controls for cut roses and unrooted cuttings in October 2025.

The practical effect for a propagation unit is that hygiene, physical exclusion and record-keeping stopped being good practice and became audited line items.

Separately, there is the propagation standard itself

Nurseries certified under GLOBALG.A.P. Integrated Farm Assurance for Plant Propagation Material (version 6.0, issued 8 July 2025) are assessed against control points that read like a description of a propagation house. Among them:

  • a hygiene procedure has been implemented (PPM 03.02.01)
  • reusable cultivation materials are cleaned so they are free of foreign material (PPM 03.02.02)
  • a schedule exists, and is followed, to clean and disinfect between batches (PPM 03.02.03)
  • equipment that touches propagation material is cleaned and disinfected (PPM 03.02.04)
  • records include the batch number of the substrate used (PPM 01.02.04)
  • registered products are traceable back to and from the registered nursery (PPM 02.01.01)
  • only plant protection products authorised in the country of production are used (PPM 07.01.01)
  • at least 10 % by volume of substrates used are alternatives to peat (PPM 04.03.02)

Read that list again with a purchase order in your hand. Four of those eight are satisfied or broken by what your supplier gives you.

The four that are actually about your supplier

The substrate batch number. If a delivery of medium arrives with no lot code, you cannot record the batch number of the substrate used, because there isn’t one. The control point is not satisfied by writing “vermiculite, fine”. This is the single most common documentary gap, and it is entirely a supplier problem.

Traceability back to the nursery. Your chain runs mother block → tray label → batch card → QC record → despatch. If the first link has no supplier reference on it, the chain does not reach back past your own gate.

Authorised products only. Anything used as a disinfectant or a plant protection product has to be registered for use in Kenya. A drum bought on price from an informal channel cannot be evidenced, and an auditor will treat “we think it’s fine” as a finding.

Peat alternatives at 10 % by volume. This one quietly changes purchasing. Vermiculite, coir and perlite are not just substitutes; under this control point they are part of how the standard is met. If you are buying peat by habit, the specification sheet is now a compliance document.

What “hygiene procedure” means in practice

An auditor is not asking whether the house is clean. They are asking to see a procedure, evidence that it was followed, and evidence that it was followed at the strength it specifies.

That means, at minimum:

  • a written dilution for each application — tool dip, footbath, bench wash, line shock, terminal clean
  • a stated contact time for each
  • a record of when footbaths and dips were refreshed
  • a safety data sheet for the product, current revision
  • a certificate of analysis or equivalent showing the strength you are diluting from

The last point catches people out. Sodium hypochlorite loses strength with heat and time. A drum bought six months ago and stored in a hot shed is not the concentration printed on it, so a dilution calculated from the label is not the dilution you made. Dating drums and rotating stock is a documentation requirement as much as a chemistry one.

Greenhouse integrity is a propagation problem too

Physical exclusion — insect-proof mesh, sealed entries, intact structures — is usually discussed as a production-house measure. It applies to propagation because young plant material is where an introduction does the most damage: one infested batch moves into every block it is planted out to.

What to have ready before an audit

A short, unglamorous list:

  • current safety data sheets for every hygiene product on site
  • certificates of analysis, or equivalent, for the batches you are using now
  • the written hygiene procedure, with strengths and contact times
  • refresh records for footbaths and dips
  • substrate batch numbers recorded against propagation batches
  • lot-level traceability from mother block through to despatch
  • your own QC records for take, losses and corrective actions

None of that is difficult. All of it is impossible to reconstruct afterwards, which is the point of keeping it as you go.

Why this matters commercially, not just procedurally

Kenya’s agricultural inputs sit in a market with a documented counterfeiting problem. In national surveys published by the Anti-Counterfeit Authority in 2025, 89.16 % of respondents named agricultural inputs as the most counterfeited product category, with the majority of counterfeit agrochemicals moving through informal channels. In that environment, a supplier who cannot produce documentation is not neutral — they are indistinguishable, on paper, from the problem the regulation exists to control.

The cheapest thing you can do about your own audit exposure is to buy from people who hand you the paperwork without being asked.
