Choose a fast-growing hedge variety. Consult your local extension service if you are unsure as to what type will grow best in your area. Most evergreen hedge varieties such as juniper, holly and cypress will grow quickly under most conditions.
Plant your hedges close together to create a privacy screen faster. Depending on the space you have available, you may want to plant more shrubs closer together to create your screen.
Purchase shrubs that are almost full grown to reduce the amount of growth time needed. You can purchase shrubs almost full-grown from area nurseries. This is a more expensive option, but the fastest way to get hedges full size quickly.
Fertilize your evergreen hedges any time from early spring to mid-summer to help them grow faster. Use a complete, all-purpose fertilizer such as a 10-8-6 NPK (nitrogen, phosphorus, potassium).
Test the soil and make sure soil conditions are appropriate for an evergreen. Evergreens prefer a more acidic soil. Adding a mulch of sphagnum peat can help enhance the acidity of your soil and encourage faster growth.
