The world’s longest fence, known as the Dingo Fence, spans over 3,500 miles in the Australian desert and costs around $10,000,000 annually to maintain. Fortunately, many low-maintenance options like the living fence exist, so you don’t have to spend your hard-earned money on upkeep.
A living fence provides all the same benefits as a man-made fence while inviting a healthy relationship with local wildlife and the environment. From deciduous to evergreen, spiny to fruit-bearing, read on to discover the best plants for your living fence.

What is a Living Fence?
Unlike the Dingo Fence, which caused animal populations to become unbalanced, living fences invite harmony with nature, creating a complete ecosystem. The natural barriers of a living fence comprise trees, shrubs, or vines instead of traditional materials like wood, chain-link, or wire.
Trees or shrubs interlock, undergoing the self-grafting process of inosculation, to create complete privacy screens and natural windbreaks. Known as living fence, agricultural fence, natural fence, or hedgerow, all provide the same benefits as a traditional fence with added greenery and require minimal maintenance once they mature.
Living fences offer many benefits to homeowners, including:
- Reduced maintenance costs
- A balanced ecosystem inviting beneficial pollinators
- Natural wind and noise reduction
- More nutrient-dense soil
- Better outdoor living
Best Shrubs for a Living Fence
Living fences come in all shapes and sizes and can include soft scape and combination types. Some homeowners opt to install traditional, hardscape fencing with plants or trees next to or on top of the artificial fence to keep children and pets inside.
Shrubs make great choices for a living fence. These plants range in size from 3 to 15 feet tall and benefit small yards. Depending on your needs and climate, deciduous, evergreen, and coniferous species are available. Many shrub species require only annual trimming, making them a great low-maintenance option.

What to Look for in a Good Living Fence Plant
A strong natural fence relies on the trees, shrubs, or plants holding it together. Growing a living fence requires a little labor and a lot of patience. You can make the process easier by selecting the right type of plants for your new fence.
Consider the following factors when making your selections:
1. Go Native
You cannot go wrong selecting native species for your living fence. These plants support local wildlife, are not invasive, and grow well in your climate.
Ask yourself the following questions to help narrow down your choices:
- What will the plants look like in your existing landscape?
- What type of soil do you have?
- Is your soil well-drained or wet?
- Is your yard and climate shady or sunny?
If you select plants outside of species native to your area, ensure they grow in your USDA zone.
2. Consider Purpose
Consider the purpose of your living fence. If it is purely decorative and a simple boundary marker, select any type of plant. If you need a natural deterrent from local wildlife like deer or coyotes, select plants with thorns or spines.
If you need year-round privacy coverage, opt for evergreen species with tight, dense branches and foliage. For quicker results, select a faster-growing species.
Many homeowners select a combination of species for their living fences. Evergreen trees make an excellent base. Plant faster-growing ornamental plants alongside for immediate coverage.
3. Maintenance
Even the slowest-growing plant needs trimming eventually. When making your plant selections, consider the time you can dedicate to pruning your new fence. Low-maintenance varieties only require annual pruning.
Ensure your living fence will not block traffic sight lines or encroach on neighboring properties by considering the height and spread of the species you select. Ensure your selections thrive when planted close together.
FAQ About Living Fences
It doesn’t matter how small or large your property is. If you have room for a man-made fence, you have room for a living wall. Simply select plants, shrubs, or trees native to your region in a size that works best for your yard – bushes for small yards, and taller, sprawling trees for larger properties.
Unlike many garden plants, trees do not need to be fertilized regularly. Fertilize the soil with a nitrogen-rich mixture before planting your seeds or saplings to ensure a healthy start.
Many fast-growing species can grow as much as 3 feet per year or more. However, all plants grow differently. Your unique climate, water, soil, and average sunlight will affect your growth rates. If privacy is your primary concern, consider planting fast-growing ornamental grass at the base of your living fence for increased density.
