Around 50 children, including Beth Higgins, four, took the chance to carve terrifying faces into pumpkins - grown in the garden.
The Botanics greenspace, in the West End, gives city children the opportunity to get outdoors.
They grow a range of vegetables, flowering plants and fruit in the special garden.
And organiser John Hancox let children celebrate the end of harvest by creating pumpkin lanterns from vegetables they had grown.
Mr Hancox said: "It's good for children growing up in the city to have the chance to see where their fruit and veg come from and be able to spend time outdoors growing things.
"I thought it was nice to mark the end of harvest, especially as it's Hallowe'en, and make the most of the pumpkins we had grown.
"One little girl refused to hand back her broomstick at the end of the day.
"But, honestly, I think some of the parents had even more fun than the children."
This year the Children's Garden, which includes a Children's Heritage Orchard, celebrates its 10th anniversary.
In the orchard, each tree is a different Scottish heritage variety of apple and was chosen as part of the Commonwealth Orchard project.
Mr Hancox has arranged a series of events to run throughout this year to mark the garden's special milestone.
The garden is open to children, families and schools all year round.
