Staff and pupils at Ripon Cathedral Primary School planted three trees to pay tribute to teacher Andrew Ebbage, who died in 2008 at the age of 51.
The cherry trees were delivered and planted by Sodexo's ground maintenance team after the head teacher approached contract manager Mick Hasson, whose daughter attends the school, for advice.
Hasson explained: "The school wanted to pay homage to Ebbage because he was a fantastic teacher who was well-loved by pupils and colleagues alike."
The Sodexo team also provided a mixture of recycled soil and compost to enhance the rough sub-soil present on the site, in line with the primary school's commitment to sustainability.
Hasson talked the children through every part of the planting, from using cable avoidance tools to correctly placing the trees.
"The very fact that a memorial to such an inspirational teacher gave the opportunity to build on the children's knowledge is very fitting and I am sure they will ensure that the trees are very well looked after for years to come," he added.
