A month on from the introduction of the new system, growers are reporting that up to 25 per cent of garden centres to which they are delivering do not have sufficient numbers of tagged trolleys to exchange, said the HTA.
This means many plants have to be hand-balled off the trolleys, adding extra time and cost to the distribution process.
HTA president Caroline Owen said: "With the season fast approaching, it is in all of our interests to make sure that the supply chain operates smoothly and efficiently. I encourage all garden retailers to pull out the stops and register their trolleys into the scheme so that we can get those plants in front of our customers."
Garden Industry Manufacturers' Association director Neil Gow, who like Owen also runs a garden centre, said: "One in three tags is not scanning from what we've seen. We haven't got a scanner and we haven't fitted the tags for our contract trolleys because most people are still delivering in untagged trolleys. I don't know whether it will bed in or not though. I hope this doesn't bugger up the industry in key times."
Container Centralen corporate marketing manager Susanne Arnsted said: " I couldn't agree with them (HTA) more - we also recommend that people get their containers tagged. Nobody wants to change tagged containers for non-tagged ones."
