Hedges
So you’ve got an area that you want to screen out. Your neighbor’s junk pile or those neighbors who have their windows at just the perfect level to look at you at all times of the day. Whether for screening or privacy, hedges are a good choice for any homeowner. Hedges are often better looking than a fence or wall,can have some sort of interest during the year, provide shelter for wildlife, and can grow to suit your needs.
What should I look for in a hedge?
Ask yourself these questions to determine your needs-
- How much room can I spare?
Often the limiting factor when it comes to hedge choice, this is really important. Sometimes you may only have a few feet to work with before the hedge is residing in your living room. Keep this in mind, as you can only fit so much in a certain space.
- What am I trying to block?
Do you want a dense screen that blocks everything, or simply something to act as a boundary line? Are you trying to block a view, or just keep people or animals out/in? Is there a sound issue? One note on sound blockage: Larger leaved plants are more efficient at blocking sound than smaller leaved plants.
- How long of an area do I have to cover?
If it’s a really long area, and you have the width capacity, you may want to consider going with a plant that spreads a bit more, as this will require fewer plants to cover the same length. For example, it will usually take more arborvitae to cover an area than any other plant. A Leyland cypress would cut the number of plants needed down to about a fifth of the number of arbs needed. Also, if it’s a long area, do you want to look at a long expanse of the same thing? You may want to consider mixing the plants in your hedge to make it more interesting.
- Am I looking for a simply functional plant, or does it have to be pretty?
Back fence hedges, or fences way out where no one notices them simply need to be functional. But when you get into a more
prominent place, like a front yard or high traffic area, you may want to consider a blooming plant, or something with some sort of interest.
How do I plant a hedge?
For small areas, planting will be the same as with a normal shrub. For long areas/more plants, you may want to dig a trench wide enough for planting, and then set the plants in and backfill. Be sure to find out about the plants’ growth habit and size, and determine the recommended spacing to use. Planting the plants too close will result in poor health down the road, so don’t fret if it looks sparse to begin with, it’ll fill in. Water your hedge deeply and regularly during the first 2-3 years.
What kinds of plants will work as hedges?
Many plant materials can be used as a hedge. Your choice should be based on your needs and experience. If you are a new gardener, or someone with limited knowledge or time, you will probably want to just use a plant from the list or ask for advice on a commonly used hedge plant. These plants have been proven successful over the years, and should work fine for you. For those of you with a bit more practice and confidence in your green thumb, go ahead and use your imagination. Just because it’s not widely used doesn’t mean it doesn’t work.
What care will maximize the health and lifespan of my hedge?
Water is usually a key issue, especially with longer hedgerows. It is recommended that you run drip irrigation the length of your hedge, so all plants get adequate water. Oftentimes sprinklers will miss some plants, and you won’t notice problems until one plant starts to die. Fertilize with a good shrub fertilizer just be sure to follow the directions on the package. Pruning is also very important. Keep on top of it! Too often people will let a hedge go for years with no pruning, and then experience poor results when they decide to finally cut that overgrowth off. This often results in a row of stumps. The trick is to mold your hedge as it grows by yearly pruning. If you even shear a little off a year, your hedge will respond by branching, and become denser and more vivid. When your hedge gets to be the ultimate size you want, keep it there! Yearly shearing will result in a more uniform, denser, healthier, and longer lasting hedge.

Emerald Green Arborvitae

Zone: 3
Full Sun
15′ x 4′ – Plant 3-5′ on center for the average hedge
Growth: Average 12″ a year in height

Drawbacks: Can not grow in shade or under trees successfully
Description: Often used for a tall hedge that naturally stays narrow. Can be sheared to make look more formal or to keep even more narrow. When shearing it is important to maintain it at the desired height or width. If you try and cut back more than the first 3-4” you start to see the brown interior. Shearing is best done in the in the spring or early summer on the new growth.
Tips: The larger the plant you start with the more water it will take to get established and Arbs don’t bounce back once they’ve gotten too dry. A simple solution to this is to set up a soaker hose going down the newly planted row both across the front and the back. This way you can water your hedge deeply without water run-off and they get the water they need evenly.
