Hard pruning Hawthorn
HI we are looking to cut back our hawthorn hedging by about 12 to 18 inches, it is a long established approximately 50 year old hedge. Is it best to do this before the leaf buds appear or leave it until late autumn. Our problem is we have a large community of hedge and house sparrows and last autumn we had baby chicks well into October. Thank you for any help you are able to give.
