Shape
An ‘A’ shaped or topped ‘A’ shaped hedge has advantages for wildlife. An ‘A’ shape
promotes thick growth at the hedge base which is important for food and shelter for
wildlife. A shaped hedges also provide an effective wind break, directing the wind over
the hedge. Tall, thick hedges with woody outgrowths are of the greatest value for
breeding birds. A rectangular shape normally means that one side of the hedge is
severely shaded, which will inhibit growth.
