Pruning a beech hedge
We have a newly planted beech hedge (well, about 3 years ago) - and we want to prune it to encourage it to be more bushy - at the moment you can still see the individual whips we planted.
Does anyone know when is the best time to do this? Is it like roses where you prune now to encourage vigourous growth ?
I know you would normally wait til much later in the season to trim a hedge - but that is when you don't want it to grow back too vigourously - so wondered whether this would be different?
