If your hedge is a species that flowers and you wish to let the hedge bloom, then you can only trim the hedge once per annum which will be straight after the hedge has flowered. This is also the case for wildlife hedges such as native species mixed hedges. Only once per annum or once every 2nd year to maximize the amount of food available for the wildlife. For formal, neat and tidy hedges this will usually be twice per annum. Hedges that are shaped or topiarized or wanted to be densely flat faced and formal, will require the most trimming by pruning off new growth shortly after it appears. Fast growing species will also need more trimming than normal to keep them from growing long branches and allowing the hedge to become loose, leggy and gappy.
