When a new wing was constructed for St Ann's Hospital in Dorset, the car park was laid out in a geometric fashion with Scots Pines (Pinus Sylvestris) planted within this geometric pattern. Tree pits were joined together to maximise rooting volume, and to give the trees the best chance of long-term survival.
Like much of this area, the soil is very sandy, and struggles to retain moisture, so a high-quality topsoil was used within the GreenBlue Urban StrataCells to ensure that the trees established well in this exposed situation.
As can be seen in the photos, the trees are growing to the leeward side – not actually leaning but growing at an angle due to the windy conditions.
Recognising the benefits that trees bring to reduce stress levels, lower blood pressure and improve mental health, GreenBlue Urban tree planting products were specified as a long-term solution to ensure that these benefits were felt by visitors and patients for decades to come.
