Why Choose a Curved or Arched Trellis for Your Garden?

These panels use a frame with shaped upper edges to provide both functional and visual benefits.

• Curved-top trellis panels create gentle arches or bow shapes, adding elegance and transforming a plain fence into a feature. Many manufacturers describe these as offering a ​“softer look” than flat-top options.
• Adding an arched trellis above an existing panel or wall increases height while maintaining a light, open feel.
• The trellis’s open lattice supports climbers such as roses, clematis, or honeysuckle. Arch-top versions offer extra planting space at the top as well.
• You can mount curved trellis panels on existing fences, walls, or posts. They work as decorative elements or as part of a fence run. A major fencing guide notes that trellis panels are often mounted on top of standard fences for extra height or fixed to walls for plant support.
• The open lattice provides privacy while allowing light and airflow. Curved designs ensure screening without feeling heavy or bulky.

What to Look for When Selecting a Curved/Arched Trellis Panel

Here’s a checklist in line with Walford Timber’s standards and garden fencing best practices: At Walford Timber, our trellis panels are built from softwood battens measuring 18 mm thick by 38 mm wide (our standard size), cut and assembled in our UK workshops. Each panel is then treated under pressure with preservatives, available in brown or green, to protect against rot and decay.
When choosing a curved or arched top trellis:

• Verify that the timber is pressure-treated specifically for durability against UK weather, including rain exposure, freezing temperatures, and fungal attack.
• Ask for a clear specification of the treatment (e.g., above-ground use)

Shape and Profile

With arched or curved-top panels, you’ll typically see two types of shape:

• Convex (bowing outwards) or concave (bowing inwards) curves depending on style.
• A gentle arch (or ​“bow top”) or a more pronounced arch (an ​“arch top trellis”). One supplier describes ​“concave/convex curved framed trellis-topper” for these uses.
  When reviewing the profile:
• Ensure the curve is well-constructed and stable (i.e., the frame supports the arch)
• Check that the height and width match your fence run or wall length
• Consider whether the arch will interfere with other garden features (e.g., roof lines, windows, neighbours)

Lattice Style and Gap Size

• Panel lattice styles include square (forming a grid), diamond (angled squares), or double trellis (two connected lattice layers). These are standard in our product range.
• When using curved or arched panels as toppers (the section above an existing panel), smaller gaps in the lattice are often preferred for increased privacy. Despite smaller gaps, these still allow light through and provide subtle screening, as emphasized by some installers.
• Decide whether the trellis is a main panel (full height) or a topper (just the curved section above).

Installation & Compatibility

• For wall-mounted or topper panels, check fixings and if the panel can be trimmed.
• If mounting above an existing fence, check that posts or cappings can support the extra width and weight safely.
• With curved panels, measure carefully so the highest part of the arch aligns with existing fence or wall heights. Slight misalignments in arch height can be very noticeable visually.
• Our own guidance page states that panels can be ​“securely fixed using panel clips or by nailing through the side battens into the post”.

Maintenance & Lifespan

• A pressure-treated timber trellis, when properly installed, will last for many years. This is why selected trellis panels supplied by Walford Timber come with ten year product guarantees.
• Curved trellis panels may expose more edges at the arch. Ensure that this curved timber section is thoroughly sealed or fitted with a cap to prevent water absorption, which can lead to rot.
• Plan for access: climbing plants add wear to fixings. Keep fixings tight and treat as needed.

Using Curved Trellis Panels in Your Garden: Ideas & Practical Applications

Here are some practical ways to make the most of a curved or arched trellis installation:

• Top existing fences with arch-trellis panels for extra height and elegance, avoiding a heavy look.
• Place a curved trellis above a gate or archway to highlight an entrance.
• Install a curved trellis against a wall or fence where you want to train climbers. The arch decorates and adds space for plants to grow.
• Use arched panels to divide large gardens into zones, keeping an open, airy feel.
• Fix a curved panel to a wall at eye level for a planting or lighting backdrop.
• Replace some flat fence panels with curved-tops at intervals to add rhythm and soften the look.

Frequently Asked Questions (FAQ)

Q: Can I simply replace my flat trellis panels with a curved top version?
A: Yes, in many cases you can — but you’ll need to check that the posts or supporting structure allow for the extra height and weight of the arch. Also, ensure the arch suits the neighbouring panels for a uniform look.

Q: Does a curved top trellis compromise privacy?
A: Not necessarily. The lattice gap and panel height determine how open or screened the finish appears. A well-selected arch-top trellis can still deliver significant screening while offering extra style.

Q: How do I maintain an arched trellis panel?
A: Much like any timber panel: keep fixings tight, ensure the top curve is free of debris and moss, treat or stain timber periodically if required, and check for damage where climbing plants attach.

Q: Is an arch-top trellis more expensive than a flat one?
A: Typically yes, due to additional timber framing and shaping. However, we believe the added style and function make it a worthwhile investment for many gardens.

If you’re looking to elevate your garden boundary, support climbing plants or bring an elegant flourish to your outdoor space, a curved trellis or arched top trellis panel is an excellent solution. With the right quality timber, correct installation and thoughtful design, this style not only adds height and screening but also a decorative feature that enhances the overall look of your garden.
