try thinking over several seasons rather than one lump of a hedge,
try these ideas plant a single row of hazel whips or willow, these are the quickest you can evan use beech or rowan or birch the idea is to start the hedge off then whilst they are growing and helping with the hedge we can plant hundreds of over plants, but rather than a single mono block of say 500 box plants lets mix it up, why not ask everyone on the forum to supply one cutting from what ever they have i would rather you pay postage but you can always promise to stick the postage money into the local church poor box instead, i would have cotton ester for a start the bees love em and as the hedge gets establised you can either cut the willow and birch out all together,
so to start it off, i offer some lavender cuttings and some cotton ester cuttings and some willow, all will be fresh cutting taken the day of postage and then wraped up in a plastic bag
