Pupils from Westfield First School in Berkhamsted joined scouts from across Dacorum in helping plant orchard trees in the garden at Ashridge House.
The children dug holes for 60 plum, pear, apple and cherry trees – all heritage varieties which are native to the county.
The project was funded by The Tree Council as part of its National Tree Week initiative.
Scouts from 2nd Hemel, 1st Apsley, 1st Kings Langley, 1st Bovingdon, and 1st Warners End also joined the schoolchildren in the task of planting the fruit trees.
Ashridge craftsman gardener Matt Smith said: “The orchard will help to improve the diversity and wildlife of the gardens.” “The trees and the meadow grass that will grow in the orchard will encourage nesting birds such as blackbirds and starlings and butterflies. It will also attract the bees and will provide them with alternative pollen.”
However, it will be around five years before the trees have matured enough to bear the first crop of fruit.
