Light annual plants can make do with slim trellises. Look for durability, easy assembly and a design that suits your garden. Our comparison will help you make the right choice.
A trellis transforms bare walls and corners into green oases. It gives your climbing plants support and structure. But which model is right for your clematis, rose or runner bean?
Our 2026 test and comparison analyses the most important criteria. We show you how to assess stability, materials and design correctly. This helps you make a confident buying decision for your garden.

What types of trellis are available?
Not all trellises are the same. The type you choose determines where and for which plants you can use it.
Wall-mounted trellises
The classic model. You attach it directly to a house wall, masonry or fence. Make sure there is enough space between the trellis and the wall. This prevents moisture build-up and damage to the façade.
Freestanding trellises and obelisks
These models do not need a wall. They stand freely in a bed or planter. They are perfect for adding height and structure to a planting scheme. An elegant example is the
climbing obelisk.
Rose arches and pergolas
They create dramatic walkways and gateways in the garden. They often support heavy plants such as roses or honeysuckle. They require a very sturdy construction and secure anchoring in the ground.
Trellises for planters and window boxes
Compact models that are integrated into or attached to planters. Ideal for balconies and patios. The
cleverly combines a planter and trellis.
Tip: For flexible solutions, sets such as the
are practical. You can distribute several small plant supports around the garden as needed.
Choosing the right material for your plants
The material determines stability, lifespan and appearance. It must be suitable for the weight of your plant.
Metal: Steel and iron
Metal trellises are very strong and durable. Galvanised or powder-coated steel does not rust. They easily support heavy, perennial plants. The design is often slim and modern.
Disadvantage: They can become very hot in midsummer. This may burn tender shoots.
Wood: Rustic and natural
Wood blends harmoniously into the garden. Pressure-treated wood (KDI) is protected against rot and lasts for many years. Durable woods such as chestnut or oak are also suitable.
Wood requires a little more care than metal. Untreated wood weathers more quickly.
Plastic: Lightweight and low-maintenance
Plastic plant supports are lightweight, weather-resistant and require no maintenance. They are well suited to light annual plants.
Stability is often limited. They can break in strong winds or under the weight of heavy plants. High-quality plastic is UV-stabilised, while cheaper versions become brittle.
Warning: Be careful with very cheap, thin trellises made of metal or plastic. They bend quickly and do not provide your plant with secure support. It is better to invest in quality once.
Assembly and fixing: What do I need to consider?
A trellis is no use if it falls over or damages the wall.
For wall mounting: Always use spacer sleeves or stand-off brackets. This allows air to circulate behind the trellis. The screws must be long and strong enough. Secure the wall plugs firmly in the masonry.
For freestanding models: Look for stable feet or a way to bury the trellis deep in the ground. With obelisks, ideally insert the rods 20-30 cm deep into the soil.
Assembly should be straightforward and possible without specialist tools. Pre-drilled holes make the work easier.
Design and shape: The invisible support
A good trellis supports the plant without taking centre stage itself.
The mesh size is important. Gaps that are too wide do not support young shoots. Mesh that is too fine can restrict growth. A mesh size of 10-15 cm is ideal for most plants.
The shape should suit the plant's growth habit. Strongly branching plants such as clematis need plenty of horizontal support points. Climbing roses often prefer to grow more vertically.
The colour should be subtle. Green, black, brown or natural wood blend into the background visually. This keeps the plant at the centre of attention.
Which trellis is right for my plant?
Here are our recommendations for popular climbing plants.
For roses
Roses become heavy and need robust support. Choose sturdy wall-mounted trellises made of metal or wood with vertical and horizontal elements. Freestanding rose arches must be extremely securely anchored.
For clematis
Clematis climbs using its leaf stalks. It needs many thin support points. Trellises with lots of horizontal crossbars or fine mesh are perfect. An obelisk in the flower bed provides an attractive climbing frame.
For annual plants (runner beans, nasturtiums)
Lighter solutions are sufficient here. A simple bamboo trellis, a slim metal trellis or a set of several stakes is enough. Browse our plant supports category for suitable models.
For vegetables (cucumbers, tomatoes, beans)
Here, stability and practical harvesting are key. Cordon tomatoes need tall, strong stakes or trellises. Cucumbers prefer wide, sturdy nets or trellises from which the fruit can hang.
Note: Always plan for something larger than you think you need. Plants grow quickly and more abundantly than expected. A trellis that is too small will only restrict them.
Care and durability
With little maintenance, your plant supports will last for many years.
Metal: Check the coating annually. Treat rust spots immediately with rust converter and repaint. Tighten any loose screws.
Wood: Check the protective treatment. If the protection is wearing off, re-treat with wood stain or oil. Areas in contact with the ground and walls are particularly vulnerable.
Plastic: Clean it in spring to remove dirt. Check for cracks or breaks, especially after periods of frost.
After the season, you can store lightweight plant supports. Heavy, permanently installed models remain outdoors.

Frequently asked questions
- Which material for garden trellises is the most durable?
- Galvanized steel or powder-coated metal are extremely durable and weather-resistant. High-quality pressure-treated wood also lasts for many years. Avoid thin, untreated wood or unstable plastic for permanent solutions.
- How do I securely attach a garden trellis to a house wall?
- Always use suitable wall spacers. This keeps the trellis from sitting directly against the facade and allows air to circulate. Attach it with sturdy wall plugs and screws in a solid substrate such as masonry. Check its stability regularly.
- Can I also use a garden trellis for tomatoes?
- Yes, particularly sturdy trellises or obelisks such as PRODUCT_74028 are suitable for this. Choose a model that can support the weight of mature tomato plants. For tomatoes in pots, mobile metal or wooden plant supports are ideal.
- What is the difference between a garden trellis and a plant support?
- The term garden trellis usually refers to flat, wall-mounted grids. Plant supports is the general term and also includes freestanding obelisks, arches, pyramids and trellises. You can find an overview in our plant supports category.
- How do I clean and care for a wooden garden trellis?
