Restoration of the walls and the planting of hundreds of plants has started at the site.
The developments have been made possible thanks to the hard work by the gardening team, volunteers and the Board.
Work is continuing on the east and south walls as well as restoring the listed sundial in the centre of the Gardens back to its former glory.
Last weekend the west border was planted out by volunteers under the supervision of gardener Donald Robertson and consultant gardener Susan Burgess, formerly of Pitmedden Gardens.
The Ellon Resource Centre have an area of the lower garden which they manage themselves and they are currently producing vegetables.
The Garden has also welcomed local clubs and societies for guided tours, and is beginning to involve local schools to use the space as a valuable enhancement of their curriculum.
Chairman Stuart Wale said: “We have an ambitious long-term programme for the Gardens to make it a stunning tourist attraction for north east Scotland and a unique community resource.
“The programme will take many years to complete and a lot of hard work to achieve, but it is something that should benefit everyone in the locality.
“A considerable amount of work is carried out by volunteers who help in the Gardens on a regular basis, helping both with horticultural work and welcoming visitors.
“If you would like to join the band of volunteers please come along to the Gardens during the week and make yourself known to someone working in the Gardens.”
The Ellon Castle Gardens is open every Tuesday, Wednesday and Thursday from 10am until 4pm. There is a small charge for non-members.
