Is it safe to clip the hedge now?Have all fledglings flown by now or do some birds hatch later in the summer? Thank you ! 1 Answers 0 Vote Up Vote Down Gerry Daly Staff answered 7 years ago In a good summer, birds may have several broods of chicks. Check the hedge before clipping. If this is a farm hedge, it cannot be cut until the end of August. Â
