Approximately 10 per cent of visitors are expected to attend from outside Scotland, "demonstrating the strength of the country's gardening industry on both a UK-wide and international scale", say organisers.
Gardening Scotland’s Floral Hall, sponsored by the Royal Caledonian Horticultural Society, will showcase more than 400 exhibitors, including plant nurseries, outdoor furniture suppliers and food and drink specialists. Local businesses such as Pentland-based Secret Herb Garden and Fife nursery East Neuk Perennials will be amongst the exhibitors.
The 2016 event has also attracted interest from further afield, and this year one third of exhibitors will come from outside Scotland, such as Warmenhoven.
Preparation for the three day outdoor living show will commence at Ingliston in late May, and will see the involvement of 25 contractors. Gardening Scotland will also create 20 temporary jobs.
Organiser Martin Dare said: "This year’s Gardening Scotland event is going to be our biggest and best yet, and the fact it will generate more than £1 million for our economy is testament of that.
"Scotland’s wider garden tourism industry generates approximately £200 million for the economy, and there’s no question that more and more people are taking an active interest in their gardens, including growing vegetables and embracing their outdoor living space.
"This event is not only about gardening though. It is also the perfect day out for foodies, families and everyone who is interested in what our great outdoors has to offer. Whether you enjoy al fresco dining, growing herbs on your windowsill, or the beautiful scent that flowers bring to an outdoor space all year round, Gardening Scotland is the place to be."
