I got a customer of mine who has a sloping backyard not even 5,000sqft. it falls off to a marsh in the backyard. My question is he is wanting some bushes that stop erosion?? i was thinking about something along the lines of junipers maybe dwarfs 3to5gal? he is eventually adding a privacy fence but wants the bushes to be tall? Im designing some flower beds for him as we speak. I was thinking about a retaining wall of some sort as an alternative? Also he was thinking about blue berry bushes whats all involved in care wise for these? any help would be appreciated thanks..
