What is a Living Fence?

A living fence is a row of trees or hedges that are tightly spaced and hardy against change. Being both tight and sturdy, they act like a standard fence . These fences can be used to separate property boundaries or different parts of your yard and come with the added benefit of being versatile and beneficial to native wildlife. A living fence comes in many different shapes and sizes, ranging from a row of sturdy trees tied together with shrubs at their base to a thick hedge of evergreen, giving you a robust screen of privacy. Depending on your climate and knowing what you’re looking for, the homeowner can narrow their search for the correct type of living fence.

Is a Living Fence Worth It?

Modern fences typically serve one purpose. They’re manufactured to be placed in the ground until no longer needed or until the dire need of replacement. A living fence establishes a barrier that can be used to provide small crops, herbs, fodder for animals, or even coppice for your fire pit. A living fence celebrating a diversity of plant species can do many things simultaneously, with the most significant difference from conventional barriers. If properly managed, it can grow for many years. Choosing a living fence for your property is a lot to consider, so take time and think about it. Take advantage of the first permaculture principle; observe and interact by seeing the site's needs before you begin. The living fence is an excellent example of the permaculture principles in motion: Integrate rather than segregate, use and value diversity, and use edges and value the marginal .

How Do You Make a Living Fence?

There are different ways to create a living fence. Some require more inputs at the beginning, while others may require more maintenance over time. Choosing the right tree can make a big difference. Let’s consider the willow tree briefly in your future living fence. They are durable yet flexible in their sapling stage, and they are great at holding soil, thus limiting erosion . The typical way to create a willow fence is to place the saplings in the ground at around 35 rods to a 10-foot line, and as they mature, weave them into a diamond lattice pattern . You can trim them to allow line-of-site through the diamonds or let them fill in as a privacy screen. As easy as they are to use in fence making, the willow also has a more nefarious side that homeowners with mature trees probably already know. Willows love moisture and will force their roots anywhere that’s wet. Willow roots will clog drains and sewage systems as it searches for water, making it less than ideal in neighborhoods and better for country properties. It would help if you also considered what you are planting around your living fence. Will you be using sun-loving or shade-tolerant plants? By placing the sun lovers on the sun-facing side of the design with shade-tolerant in the back, you create a level of complexity from the two different microclimates. Introducing nitrogen-fixers can be a great way to help feed your hedge by pulling that free nitrogen out of the air and putting it back into the soil. Plants of the Alnus genus—or alders—are nitrogen fixers and make great additions between your staple fence trees. Try planting an average of one alder for every two or three trees. Or better, use the same principles of a food forest and different layers of beneficial plants to support the hedge.

Are Living Fences Secure?

If security is an issue, consider some naturally defensive plants at locations across the property. If you’re in the southwest, you may find the cactus as a fantastic guard. Living up north, you can consider plants like thorny blackberry or even rose bushes for food, drink, and deterrence. Even honey locusts with their aggressive thorns can be a deterrent.
