I have a large boundary of conifers at the bottom of my garden. They are hedged up to about 14 foot and then tree out with lots of branches. I have asked our gardeners to tidy the hedge area by trimming it up with hedge cutters. They are not known for their over activity and I was told that it was the wrong time of year to do this and would result in conifers going brown and that this should be a winter task. Does anyone now if this is true? Logically I would have thought now was better when there is sunshine and no frost but I have no idea. Thanks.
I think all trees are best cut in Autumn winter aren't they? When there is no sap rising or something. I cut the lower branches off my mum's conifers years ago in a mis-guided attempt to 'tidy them up', and they never re-grew. She was left with very bare trunks with just a tuft of green at the top
