Youngsters from Western Primary School and staff from Bettys donned their wellies to plant young willow whips.
The willows, which will help to conserve the soil on the upper meadow following the winter storms, are marking the next stage of Bettys & Taylors Trees for Life Wood in partnership with the Royal Horticultural Society.
The family business is working with the RHS to create the woodland.
In all it will host 1,000 trees, with an emphasis on native species, and will illustrate the uses of trees in transport, livelihoods, food and fodder, shelter and medicine as well as their fundamental role in helping to prevent and adapt to climate change.
Bettys & Taylors Trees for Life champion, Sam Gibson, said: “It is wonderful to see the progress of the woodland.
“Through our planting and protection projects we’ve come to realise the huge value of trees, not only to our planet, but also to the communities who depend on them around the world.
“We hope the Trees for Life wood will provide an opportunity to share our passion for trees with local schools and Garden visitors alike.”
Paul Cook, Curator at Harlow Carr said: “New tree planting is crucial to keep woodland rejuvenated and to provide woodland for future generations to enjoy.
“It is an exciting opportunity to use the new woodland to educate our visitors on the uses of wood for building, medicine, and art.
“It is great to be working with Bettys to bring a new area of Harlow Carr into life for everyone to enjoy”.
