ABSTRACT
The number of plants required to cover a certain area of ground is dependent on a number of factors – the habit, form, growth rate, and eventual size and spread of the plant. The prior table is calculated from a rectangular grid arrangement of planting, where the area of planting is divided by the square of the planting distance. However, unless a specific geometrical effect is required, odd number plant groupings, with the plants arranged in loose staggered rows, usually work best visually. Converting densities from the plan to planting on site needs to take account of the third dimension, where the actual area of ground to cover on a slope is greater than the area measured from the plan.
