Gardening Scotland, which returns in May for its 10th anniversary, will feature more show gardens than ever before and many new grower exhibitors.
The centrepiece of this year's event will be a labyrinth created by the British Trust for Conservation Volunteers (BTCV). Other exhibits will feature edible crops in place of flowering plants.
Gardening Scotland chairman Jim McColl said the rise in the popularity of grow-your-own and grass-roots gardening among community groups, schools and volunteer organisations was behind this upsurge in interest.
"Many people are turning to gardening at the moment and that is reflected in the strength of this year's show," he said.
