I would leave it alone until it gets some new growth on, if you trim it now you will be cutting the new growing points off, and may take some time for it to develop new growth buds, Derek.

My beech, in fact most of the trees are very late this year, they have buds that are starting to get ready to open, more of this lovely sunshine will help
Spring I think is at least three weeks later than normal this year

Thank you for the advise! I will leave the trimming until later in summer.

The advice we read and follow is to cut beech hedges in early autumn.

Generally we get the hedges cut in the autumn,
After the birds have finished nesting is important, some birds have second broods and. Dislike disturbance
Our are mixed country hedges so the man with the flail hedger does it.....
