The Garden Centre Association (GCA) has released a further three modules as part of its e-learning initiative Garden Retail Online Workshops (GROW).
The latest modules for the scheme include wild bird care, starting a new lawn and soil types.
GCA interim chief executive Iain Wylie said: "Our e-learning initiative has really taken off and we now have 49 modules available.
"We understand a lot of our members don’t have the time or resources to fully train all of their staff, so we came up with this idea to keep their customer services standards at the highest level possible.
"We plan to keep on adding further topics that will focus on all areas involved with running a garden centre. We are currently working on two further lawn-care modules, which will be available later this year."
GROW is available to all GCA members to ensure their staff are fully trained with minimal input required from management.
The aim of the GROW e-learning modules is to give garden centres an opportunity to train all their staff to ensure they have a basic horticultural understanding.
Wylie added: "All our members who have signed up to GROW so far have been incredibly impressed and enthusiastic so we want to remind those that have not yet registered that they can sign up now to get the full benefit from all the modules.
"Members who would like to find out more should contact firstname.lastname@example.org."
Meanwhile, the GCA has advertised the chief executive role. Wylie took over from Phil Slinger, who was at the association for a short time last year having succeeded Gillie Westwood. Wylie said he was enjoying the role and that it was always planned to advertise the post. It's understood Wylie may apply.
