Cotoneaster shrubs are often used for a privacy fence. The leaves of this shrub are dark green and the shrubs can grow to heights of 10 feet. Growing cotoneaster shrubs for a hedge doesn't require much care or pruning. During the summer, the cotoneaster hedge will have small, star-shaped flowers that attract bees. In the winter, the cotoneaster hedge produces red or orange-red berries that provide a source of food for birds and other wildlife. Determine how many cotoneasters are needed for your hedge by measuring the area's length and then dividing that number by 12.
Dig a trench 12 inches wide and 12 inches deep down the entire length where the cotoneaster hedge will be planted. If planting the cotoneaster between two property lines, plant the cotoneaster 1.5 feet within your property line.
Amend the soil that you removed from the trench with a 2- to 3-inch layer of compost. This will provide nutrients for your hedge to grow.
Fill the trench with water. This gives the cotoneaster hedge a head start and ensures that the water goes deep into the ground. Allow the water to drain naturally away before going to the next step.
Insert the cotoneaster's root ball into the trench. Space each cotoneaster 12 to 15 inches apart, after the water has drained into the soil.
Push the amended soil into the trench around the root ball, filling the trench only half full.
Lightly firm the soil around the root ball.
Water the hedge, filling the trough. Watering at this point helps remove any air pockets in the soil. Continue filling the rest of the trench with amended soil until the root ball is even with the soil. Firm the soil down with your hands or foot.
Water the hedge with a dripper hose around the hedge tree's roots. Keep the soil moist until the cotoneaster hedge is established.
Cover the ground around the hedge trees with a 2- to 3-inch layer of organic material.
