Trewithen trees cut carbon footprint

Trewithen Gardens unveils a green initiative, planting 9,000 trees to combat climate change, enhance biodiversity, and captivate visitors.


Visitors will be able to see the mixed conifer and broadleaf trees, sourced from regional suppliers, when the top-rated garden re-opens for the season on Saturday, March 1st. Trewithen's owner, Michael Galsworthy said: "Tree planting to me is always a top priority but in this day and age we also need to off-set our carbon footprints."

"Research shows that over a year one hectare of mature woodland can absorb the carbon emissions of 100 average family cars. The nine thousand trees we have planted cover 10 hectares and as they are young they will be even more efficient at absorbing carbon dioxide which they use to fuel growth."

Trewithen's woodland manager, Bryan Elliot, explained that the new trees will also link up the estate's existing woodland areas and create corridors for wildlife as well as acting as wind breaks.

Although the new trees are not part of the main gardens famous for early flowering Magnolia, Camellia, Azalea and Rhododendron, visitors will be able to see them on the garden's woodland walk.

The newly planted species include classic English trees like Ash, Oak, Sycamore and Chestnuts as well as conifers and other evergreen trees.

Head Gardener, Gary Long explained that unfortunately there will be no beech trees – in fact many of the existing Trewithen Beeches have needed replacing recently as the species is no longer flourishing in Cornwall.

He said: "The problem is that the Beech has a shallow root and has not adapted to the changing weather patterns of long periods of drought followed by flood. Evidence shows that Beech are ‘migrating' and are far more likely to grow well in the North East of the country now."
