The three-week festival will also include daily talks, tours and demos across a wide range of gardening topics for gardeners of all abilities. It is free with an Eden Project day ticket.

The hour-long talks will cover everything from allotments and growing your own, to composting, wildlife gardening, flowers and ornamentals, and exotic gardening.
