Hi - we have a very exposed small garden with a frequent, strong south west wind. (It blew a secured 10ft trampoline 2 fields away last winter!!). We'd like to plant a new hedge and favour some fruit bushes. My preference would be for blackcurrant, raspberry and, if possible, a smaller sloe. I'm just not sure if they would survive. Should we mix with other hedging? Is there anything we can do to make it stronger?
