Squires Wokingham is pledging to donate hundreds of silver birch trees in September.
The scheme aims to collect 5p from every customer who purchases a plant or tree in Squires to plant trees.
Wokingham Borough Council is working with the garden centre to make spaces greener.
Sarah Squire, Squires chairman, said: “We strive to be part of the local communities where our garden centres are.
“We want to thank our customers by giving back to the local area. What better way to do this than by providing Silver Birch trees that people can enjoy for years to come?
“Silver Birch’s are native British trees that are fantastic for the environment. They can improve air and soil quality, and they are great for wildlife too.”
In 2018, the garden centre donated over 230,000 tulip bulbs to brighten spaces in the area.
Councillor Gregor Murray said: “It’s great to see local businesses doing what they can to help fight climate change. I commend Squire’s garden centre for their scheme, and for giving something back to the local area.
“Tree planting is an essential step in offsetting our carbon footprint across the Wokingham borough. Silver birch trees are a fantastic choice.”
