Drawing of trees on fence line

In this guide, we’re exploring the best trees to enhance your fence line. Whether seeking privacy, shade, or beautifying your boundary, the right tree can transform your space. 

Each tree offers unique benefits, from the lush Lilly Pilly to the majestic Jacaranda. Join us as we unveil 14 superb choices that thrive in Australia’s diverse climates, ensuring your fence line is not just a boundary but a highlight of your garden. 

Can trees grow around fences?

Trees can grow around fences, but it’s a dance of balance and understanding. When we plant trees near fences, we invite nature to coexist with our manufactured boundaries. The key lies in selecting the right trees and understanding their growth patterns.

Root systems are the underground architects of a tree’s life, and they can be as expansive below ground as the tree is above. Some trees have deep taproots that dive straight down, while others spread beneath the surface. It’s these outward-bound roots that can play friend or foe to fences. They might sneak under a fence, lifting and warping it over time or grow into and around it, causing structural damage.

The challenge is to choose trees with root systems that are less invasive and more fence-friendly. It’s a bit like choosing a housemate – you want someone who respects your space and doesn’t take over the living room! With careful selection and strategic planting, we can enjoy the beauty and benefits of trees without compromising the integrity of our fences.

Benefits of planting trees along a fence line

Planting trees along a fence line is like giving your garden a multifaceted gift. Let’s unwrap these benefits:

  • Privacy: Trees are nature’s privacy screens, especially for narrow spaces. Tall, dense foliage can shield your space from prying eyes, creating a secluded oasis. Imagine relaxing in your garden, surrounded by the leafy embrace of a Lilly Pilly or the broad leaves of a Magnolia ‘Little Gem’.
  • Shade: On scorching summer days, these green giants are saviours. Their canopy offers a cool retreat, lowering temperatures and providing a comfortable outdoor space. Picture lounging under the dappled shade of a Crepe Myrtle or the wide umbrella of a Moreton Bay Fig.
  • Wind protection: Trees are natural windbreakers. They soften the blow of harsh winds, protecting your garden and home. This is especially beneficial in areas prone to strong winds or coastal breezes. The robust form of an Eucalyptus or the dense foliage of a Bottlebrush can be particularly effective.
  • Aesthetic appeal: Trees add an artistic touch to your landscape. They bring colour, texture, and structure, enhancing the overall look of your property. Whether it’s the vibrant purple blooms of a Jacaranda or the unique shape of a Queensland Bottle Tree, these living sculptures make your fence line a visual delight.

In essence, trees along a fence line are more than just plants; they’re functional, living elements that enhance our quality of life and the beauty of our surroundings.

Considerations before choosing trees for your fence line

When selecting trees for your fence line, it’s crucial to consider several key factors to ensure they complement rather than complicate your garden space. Here’s what to keep in mind:

  1. Tree size: Understand the mature size of the tree – both height and spread. A tree that grows too tall or wide could overwhelm the space, overshadow smaller plants, or even overhang into neighbouring properties. Compact trees like the Magnolia ‘Little Gem’ might be ideal for smaller spaces. At the same time, larger areas can accommodate the grandeur of a Moreton Bay Fig.
  2. Root system: The root structure is a hidden but vital aspect. Some trees have invasive roots that can damage fences, underground utilities, or the foundation of nearby structures. Opt for trees with non-invasive roots to avoid future complications. For instance, the Olive Tree (Olea europaea) is known for its less aggressive root system.
  3. Growth rate: Consider how quickly the tree grows. Fast-growing species provide quick coverage and privacy, but they might require more frequent pruning and maintenance. Slower-growing trees, on the other hand, take time to establish but typically need less upkeep. Crepe Myrtles are an example of fast-growing trees, while Japanese Maples grow more slowly.
  4. Maintenance needs: Some trees require regular pruning, watering, and other care to stay healthy and look their best. Assess how much time and effort you’re willing to invest in maintenance. Trees like the Bottlebrush (Callistemon) are relatively low-maintenance, making them a popular choice for busy gardeners.
  5. Local climate: Trees must be suited to the local climate to thrive. Consider factors like temperature extremes, rainfall, humidity, and soil type. A tree that’s well-adapted to your area’s conditions will be more resilient and require less intervention. For instance, Lemon-Scented Gum (Corymbia citriodora) is well-suited to warmer climates.

By carefully considering these factors, you can choose trees that enhance your fence line and thrive in your garden, creating a harmonious and sustainable landscape.

Planting and maintenance tips

When planting and maintaining trees along your fence line, following the right techniques and care practices is crucial for the health and longevity of the trees. Here are some practical tips to ensure your trees thrive:

Planting techniques

  • Choose the right location: Ensure enough space for the tree to grow above and below ground. Consider the tree’s mature size and root spread.
  • Dig the right size hole: The hole should be twice as wide as the root ball and just as deep. This allows roots to spread easily.
  • Position the tree correctly: The top of the root ball should be level with the ground. Avoid planting too deep or too shallow.

Soil preparation

  • Test the soil: Understand your soil type and pH level. Amend the soil if necessary to suit the specific needs of your planting tree.
  • Add organic matter: Mix in compost or aged manure to improve soil fertility and drainage.

Watering

  • Water deeply and regularly: After planting, water the tree deeply to settle the soil and eliminate air pockets. Regular watering is crucial during the first few years.
  • Mulch: Apply a layer of organic mulch around the tree’s base to retain moisture and regulate soil temperature.

Pruning

  • Prune for shape and health: Remove dead, damaged, or crossing branches. Prune to maintain the desired shape and size, especially for trees grown for privacy or aesthetics.
  • Best time to prune: Generally, the best time to prune is during the dormant season. However, this can vary depending on the tree species.

General care

  • Fertilising: Following the manufacturer’s instructions, apply a balanced fertiliser in early spring to promote healthy growth.
  • Pest and disease management: Regularly inspect for signs of pests or diseases. Treat promptly with appropriate methods if any issues arise.
  • Protection from elements: In extreme weather conditions, such as prolonged drought or frost, provide extra care like watering or frost protection.

Remember, each tree species may have specific needs, so it’s important to research the particular requirements of the trees you choose for your fence line. With proper planting and care, your trees will grow healthy, strong, and a beautiful addition to your landscape.

Challenges in maintaining trees along a fence line

Maintaining trees along a fence line can pose unique challenges. Awareness of these issues and implementing strategies to prevent or mitigate them is key to ensuring a harmonious coexistence between trees and fences.

  1. Root invasion: Tree roots can grow extensively and potentially invade the area under fences, leading to lifting or cracking. To avoid this, choose tree species with non-invasive root systems. Consider installing root barriers when planting to direct root growth deeper into the soil and away from the fence.
  2. Overgrowth: Trees can grow larger than anticipated, causing overhanging branches that may intrude into neighbouring properties or interfere with fence integrity. We recommend regular pruning to control the size and shape of the tree. Be proactive in trimming branches that come close to the fence line. Selecting the right tree species that match the available space can also prevent overgrowth issues.
  3. Fence damage: Apart from root invasion, falling branches or increased shade and moisture can deteriorate fence materials over time. Consequently, regularly inspect the tree and the fence for early signs of damage. Prune any dead or weak branches that pose a risk of falling. If possible, choose fencing materials that are resistant to rot and moisture. Providing adequate space between the tree and the fence can also reduce the risk of physical damage.

By understanding these challenges and taking proactive steps, you can enjoy the benefits of having trees along your fence line while minimising potential issues. Regular care, appropriate tree selection, and preventive measures are key to maintaining a healthy and beautiful fence line landscape.

Design ideas for fence line trees

Integrating trees into your fence line can transform a simple boundary into a stunning landscape feature. Here are some creative layout and design ideas to effectively incorporate trees along your fence line:

  1. Layered planting: Create depth and interest by planting trees of varying heights and forms. Place taller trees like Eucalyptus or Jacaranda at the back and smaller ones like Crepe Myrtle or Bottlebrush in front. This staggered approach can create a visually appealing, multi-dimensional effect.
  2. Symmetrical planting: For a formal look, plant trees along the fence line at regular intervals. Choose uniform trees like the Magnolia ‘Little Gem’ or Lilly Pilly and prune them to maintain a consistent shape and size.
  3. Mixed borders: Combine trees with shrubs, perennials, and grasses for a diverse, layered border. This not only adds variety in texture and colour but also supports biodiversity. For instance, pair the Lemon-Scented Gum with native shrubs and flowering ground covers.
  4. Espalier trees: Train trees like Olive or certain fruit trees to grow flat against the fence in an espalier pattern. This technique is perfect for narrow spaces, adding a unique architectural element to your garden.
  5. Natural screen: Create a privacy screen with fast-growing, dense trees like the Tuckeroo or Sydney Red Gum. Allow them to grow naturally for a lush, informal hedge that provides privacy and wind protection.
  6. Focal points: Use striking trees like the Illawarra Flame Tree or Jacaranda as focal points at corners or gates. Their vibrant blooms can draw the eye and add a splash of colour.
  7. Canopy overhang: If space allows, let the canopy of larger trees like the Moreton Bay Fig overhang the fence slightly. This creates a sense of enclosure and cosiness, perfect for creating a secret garden feel.
  8. Wildlife haven: Choose trees that attract birds and wildlife, like the Bottlebrush or Eucalyptus. Planting these near bird feeders or baths can create a lively and engaging environment.
  9. Climber support: Plant trees that can naturally support climbing plants. For example, a sturdy tree like the Lemon-Scented Gum can support climbing roses or jasmine, adding another layer of beauty.
  10. Seasonal interest: Select trees with different colours and textures throughout the seasons. For example, combine the autumn foliage of Japanese Maple with the spring blooms of Crepe Myrtle for year-round interest.

Remember, the key to successful fence line tree design is to consider the trees’ growth habits and maintenance needs in relation to the available space and overall garden style. With thoughtful planning and creativity, trees can enhance the beauty and functionality of your fence line.

Final Thoughts

Incorporating trees into your fence line is not just about aesthetics; it’s a commitment to enhancing your environment sustainably. Choosing the right trees, considering their growth habits, and maintaining them responsibly creates a living boundary that offers privacy, beauty, and a haven for wildlife. 

Embrace this opportunity to positively impact your landscape and the ecosystem, one tree at a time.
