Thanks, Lowenna ... that's very encouraging! We do have established (70-odd years old) privet hedges in other parts of the garden but are about to replace a 6' tall Lleylandii hedge which is dying (YAY!!!). We live just outside Edinburgh, so I suspect a new privet hedge may take a little longer than yours in Cornwall to give us back the privacy that the Lleylandii provided, but perhaps not! Only 16 months ago I planted a mixed hedge - hazel, guelder rose and sloe gin

to reinforce an old hawthorn hedge and it has raced away ecstatically
