The national flower and outdoor living show, which next year will take place from Friday, 30 May until 1 June at The Royal Highland Centre, Edinburgh, will have a dedicated area for show gardens.
Show director Martin Dare said: "We are delighted to welcome David Wilson Homes as Show Garden Avenue sponsor for 2014. The show gardens are one of the most hotly-anticipated features of the event and the David Wilson Homes brand is synonymous with high quality and great design.
David Wilson Homes East Scotland sales director Anne Ross said that gardens were high on the wish list of many home buyers and David Wilson homes were designed with the importance of outside space in mind.
Gardening Scotland has been held annually for 15 years and attracts more than 35,000 visitors.
As well as the David Wilson Homes Show Garden Avenue next year's show will include a plant fair, a cookery theatre, workshops with gardening experts and more than 400 exhibitors selling everything for the garden.
