Select a fast-growing plant for your hedge. Boxwood, privet or Leyland cyprus grow very quickly.
Plan the layout of your hedge. Make allowances for walkways and driveways that may border your hedge. Although hedges can grow to a variety of sizes, plan for your hedges to reach their upper limits. Many hedges are 2 or 3 feet deep although you can grow them to be bigger, if desired.
Remove any grass or sod, with a shovel, from where you are planting your hedge.
Estimate the number of plants you need for your final hedge. Because different varieties of hedges require different planting distances, talk with your nursery or plant supplier for proper planting density.
Prepare the soil either by roto-tilling or digging down 2 or 3 feet to loosen the soil. Break up large clumps and clods.
Remove the plants from their containers and dig out an area larger than the root ball.
Place the young tree in the hole and backfill the hole. Different types of hedges may do well with different types of fertilizer, however, adding a handful of fish meal or other natural organic fertilizer helps almost any hedge planting.
Plant all of your trees at the recommended density for the variety you have selected. Make sure they are in a fairly straight line as it will take some time for your hedge to grow in. The exact amount of time will depend on the variety and your local growing conditions.
Water your hedge for the first time, ensuring that the top several inches of soil are wet.
Water the hedge with an inch or 2 of water each week for the first couple of weeks, then taper off as the root structure begins to grow.
Prune the hedge to the desired shape once your hedge has started to grow in. At first, you can prune the hedge to a size smaller than your eventual desired size. However, this will slow the growth of your hedge. For fastest growth, consider letting the hedge get to its desired size before the first pruning.
Prune your hedge lightly a few times a year to encourage thick growth. Single annual prunings don't encourage as much thick growth, which is desirable in a privacy hedge.
