Planting a new English yew (Taxus Baccata) hedgerow along the front garden boundary between our property (number 13) and house number 15, where there is currently no hedge in place. The aim is to improve the definition of the border and make it easier to maintain, as weeds are currently growing through. A very small section of the existing hedge near the pavement will be removed so the new hedge can join seamlessly and fill current small gap
