We welcome applications from previous members of the Institute who would like to re-join. To ensure our records are up to date, please complete and return the Rejoin form, together with a direct debit form.
If you wish to upgrade your membership when you re-join the Institute, we will also need an up-to-date CV or completed Qualifications and Experience Form, together with copies of certificates for any qualifications gained since your membership lapsed, to enable the appropriate membership grade to be assessed. A referee will also be needed if you are applying to upgrade your membership when you re-join the Institute. Upgrading your membership may entitle you to additional membership benefits.
Upgrading will depend on your current qualifications and experience. Please check the membership criteria for guidance on the qualifications and experience needed for each grade of membership. If you are not sure of the appropriate grade, please leave this section blank, in which case your application will be assessed according to the membership criteria, and you will be informed of the outcome.
Please note that there are separate processes if you wish to become a Fellow of the Institute or to apply to be granted the title of Chartered Horticulturist.
PDF versions of all the Forms can be downloaded on the right of this page. These documents are in Adobe Acrobat format. If you don't have the reader, please follow this link to Adobe and install the free reader.
