What the experts say. 1  One of the best black runs in the Alps, the Piatta de Grenon is scarily steep in parts, but with plenty of terrain so you can let your skis run and build up speed. Catch the Coulis 2 chairlift, then ride the small escalator to the top, wizz back down and repeat until your legs give in.
The height that a shrub will grow is dictated by its species and to a lesser extent by its variety. No matter how much fertilizer you give a barberry shrub, for instance, it will never grow much taller than 2 feet in height.
A plant/tree/shrub marked slow growing will only grow about 6 inches or less a year when established. A plant marked medium will grow between 6 to 12 inches per year. A plant marked fast growing will grow 12 inches or more a year. This assumes the plant is planted in optimum conditions. Factors that will effect growth are, how much sun, morning or evening sun, water and dirt. So too your Boxwood. A boxwood in the Midwest is usually considered a slow grower.
