These always make two growths in the season, and the best time to
perform the clipping or dressing of them is before the plants begin
their second growth. Choose if possible dull and cloudy days for the
operation. The general practice in forming these, is to have the sides
even, and the top level, forming a right angle on each side. However
neat in appearance this may be considered, it certainly is stiff and
formal. We never approve of shearing where it can be avoided, and when
adopted, nature ought to be imitated. We consider that all hedges and
edgings ought to be narrowed at the top.
