Among places Don has filmed for the series are Kew and Glendoick Gardens in Perthshire, where owner Ken Cox talked about plant hunting.
Don is also filming this spring and summer a new BBC show called Big Dreams, Small Spaces, creating gardens for people with little space.
Don presents Gardeners' World for the BBC, which returns to BBC2 on around March 6 as well as the BBC's RHS Chelsea Flower Show coverage.
Don has also been confirmed as the keynote speaker at the 9 March supply chain efficiency project Horticulture Wales is staging titled Bringing Growers Together at the National Botanic Garden of Wales, Carmarthenshire. The event is a one-day conference specifically for fruit, veg, flower, plant, and tree growers, along with other representatives from the wider horticulture industry.
In addition, Stephen Hedderly, Bedfordshire Growers managing director, will speak at the Carmarthenshire event about the opportunities offered by collaborative working, while Simon Goodenough, curator of horticulture at the botanic garden will explore the role of botanic gardens in the 21st century and how they can build relationships with commercial growers.
