For over 20 years the HGT has been actively involved in researching historic landscapes in Hertfordshire, protecting them for future generations to enjoy and, through our education work, encouraging children and schools to get involved with horticulture. We also run a popular programme of outings, lectures and fundraising events for members. Please read more of what we do on this website.

The Trust's new Constitution, adopted on July 16, 2013, is available as a downloadable file click here to download.

From the President:

“Our new Chairman has not let the grass grow under her feet and under her leadership this has been another productive year for the Hertfordshire Gardens Trust.

There is plenty of activity in all departments which is impressive.  The Hertfordshire Gardens Trust provides interesting opportunities for its members and I do encourage you to bring your friends along to see what is going on as there is something of interest for everyone.  It would be an advantage to widen the circle of membership."
