I'm interested in surrounding my UK front garden with a evergreen hedge border.
The garden is small, enough for 2 small family cars.
So is it possible to grow a "slim" evergreen hedge which is at least 6ft high?
Yews should do the job as they can be trimmed easily and sprout new growth on old wood. They are slow growing unless you pamper them with water and fertilizer the first few years.
Even easier, and thinner, is a wood/aluminium/steel fence with vines growing on it. You can get privacy, flower and fruit with less than three feet of width. Some vines that would work are roses, clematis, wisteria.
