Grower Technical Workshops

The workshops are a great opportunity to catch up with developments in key areas of production, see a range of trials and demonstrations undertaken within a commercial environment, exchange findings and results and generally network with other growers and colleagues.

Please find below a summary of the grower member workshops and masterclasses for 2024, in association with Zest Sustainable ICM, covering a range of topical technical subjects, on various nursery locations around the country.

Note, that the workshop format is the same as in previous years - up to 30 delegates, nursery and local venue based, with various presentations and practical applications; while the new masterclass format is - up to 10 delegates, nursery based, more in-depth detail, a chance to modify your own programmes and procedures.

Please book into those that are relevant. Note, that there is a limit of two people per business for the workshops, and one person per business for the masterclasses to allow as many member businesses to attend as possible.

More detailed content will be e-mailed out in advance of each event and BASIS and NRoSO continual development points will also be made available. If, having booked, you are unable to attend for any reason, please inform us as soon as possible so we can offer the space to other HTA members.
