I live in south western Ontario, Canada (zone 5B) and want to plant a living privacy fence (approx. 40 ft) around part of our lot. We want something that: - will stay thin and not bush out (max 6') - about 15' height in about 10 years - it will have full sun - no problems with deer or any animals - shallow roots, as part of the fence goes over the septic system. What should we plant???
