The Tender Shoots Garden Club Network is a national collective of UK garden clubs set up by a novice gardener ( Indy Rana ) during Covid so clubs could work together. They hold gardening talks over the autumn and winter months via Zoom. Individuals and clubs are very welcome to join, it’s open to anyone, and there’s no charge to attend, click here for more information
There are lots of talks on a very wide range of topics. Zoom meetings are held both evenings and afternoons. There is sure to be something of interest to you.
