10+ Best Materials for a Trellis (Plus Where to Find Them)

A trellis is a great way to support flowering or fruiting vines that like to climb, such as tomatoes, squash, clematis, and roses.   But what material is best for a trellis, and how do you decide when to use each one? 

So, what are the best materials for a trellis?  The best materials for a trellis are bamboo, aluminum, and vinyl.  Bamboo is best for a natural appearance that will last.  Aluminum is best for a light trellis that won’t rust.  Vinyl is best for vines that do not produce fruit.

Of course, there are many more materials to choose from.  The material you use for your trellis will how long you want it to last, how much you want to spend, and what you are planting.  Let’s take a closer look at the best trellis materials.

What are the Best Materials for a Trellis?

There are four basic categories of materials you can use for a trellis:

  • Wood
  • Metal
  • Plastic
  • Recycled (can be made of any or all three of the above categories)
A trellis can be made of wood, metal, plastic, or other recyled materials.

When making your decision on a trellis material, the main factors to take into account are:

  • Availability (how widely available is the material?)
  • Cost & Availability (how expensive is the material?)
  • Durability (how long will the material last?)
  • Effort (if building a custom trellis, how difficult is it to work with the material?)
  • Type of Plants (what plants will you be supporting with the trellis?)

Let’s start off by taking closer look at the types of wood you can use for a trellis, along with when you might want to use each one.


No other material can match the natural appearance of a wood trellis.  It is easy enough to work with, as long as you have the right tools available (saw, hammer & nails, or screwdriver & screws).

Although wood is sturdy, it will eventually rot, unlike metal or plastic materials.  Wood is best used for a trellis that is easy to move or replace (like a lean-to trellis lying against a fence, or a vertical trellis on a wall).

A wood trellis with a lattice pattern allows plants to climb, but it will eventually rot away due to the elements.

There are many types of wood you can use for a trellis, some of which are much more expensive than others.


A bamboo trellis can last up to 10 years before it needs to be replaced.  Bamboo is strong, so it can hold up to the weight of vining and fruiting plants.  It is also lightweight, making it easy to move if you change your mind about the location.

Bamboo is strong but lightweight, making it a good choice for a trellis to support plants.

You can buy a ready-made bamboo trellis from a garden supply store.  For example, this expandable bamboo trellis from Home Depot allows you to adjust the height and width as you like.

You can also build your custom bamboo trellis.  All you need to do is to buy your own bamboo stakes, such as these ones from Gardener’s Supply Company.

You could drive bamboo stakes into the ground in a row and connect them with wires or twine at varying heights.  This would give your plants a few different wires to hold on to.  It would also help you to keep your rows straight!

Bamboo is somewhat expensive, so it is best used for a quality trellis that you can use for years to come.

Soft and Hard Woods

Using wood for a trellis might not be a problem if you want a temporary support structure for your plants.  After the wood rots away, you can use the leftover material as mulch, or add it to your compost pile.

Just make sure the wood is untreated if you put it in your compost pile!  Treated wood contains chemicals that can leach into the soil and then into your plants.

After a trellis rots, you can build a new one and put it in a new location.  This is useful if you like to experiment with growing in different areas of your garden.

Here is a list of common types of wood you might use for a trellis.  They are listed in order from least to most rot-resistant:

  • Pine – a soft wood, often used for furniture.  It is not quite as useful for outdoor projects, since it does not resist the elements.  Pine does not hold up well when exposed to soil, water, and insects.  In most cases, this wood will rot within a few years if untreated.
  • Oak – a hard wood, which is stronger than pine, but more difficult to work with.  Oak will last longer than pine when used for building a trellis.
  • Cypress – a soft wood, which nonetheless holds up against rot when it comes in contact with wet soil.  Cypress contains natural oils that preserve the wood so that it can resist decay and insect damage.
  • Cedar – a soft wood, this one holds up very well against the elements in outdoor conditions.  Much like cypress, cedar contains its own natural oils that help to protect it from insects and rot.  Remember that the red appearance of cedar will naturally fade to gray over time, before the wood eventually rots.  Cedar is more expensive than other types of wood.  Here is a cedar grid lattice, available from Home Depot.
  • Redwood – a soft wood, which is one of the longest lasting.  Even in outdoor conditions when exposed to wet soil and insects, redwood is a champion at resisting the elements.  Redwood is very expensive, but it can last up to 30 years.  Here is a redwood garden lattice, available from Home Depot.
Redwood is expensive, but it holds up well against the elements, even if untreated.

Keep in mind that you can treat or paint wood to make it last longer outside.  However, you need to be careful about leaching chemicals into the soil and into your plants, especially if you grow vegetables or fruit on the trellis!

Heavier wood is a good choice for a trellis that needs to support more weight.  For example, a trellis meant to support lots of tomato vines, which will become heavy as the plants grow taller and produce fruit.

Wood is easy to work with, since you can cut it to the size you want or find someone to do it for you.  Some of the wood listed here is expensive, but you will pay a higher price for more durable wood that lasts longer in the great outdoors.


If you want a strong, durable trellis and you don’t care about a natural appearance, then metal might be the right material for you.

Some metal, such as wrought-iron, are heavy, making it difficult to move a trellis after it is placed.  Metal is also a bit harder to work with than wood.

You have a few different options if you choose a metal trellis.

Wrought Iron

Wrought iron trellises are beautiful, but iron is one of the heaviest materials you could use for a trellis.  A wrought iron trellis is sturdy and will hold plenty of weight from vines and even fruit on your plants.

A wrought iron trellis is heavy and sturdy, but it will rust over time.

However, the weight of a wrought iron trellis means that it may not be able to stand on its own.  You will probably need to prop a wrought iron trellis against a wall or fence, or else drive supports deep into the ground to keep it upright.

Wrought iron will resist rust, but it is not completely rust proof.  You can find wrought iron with a special finish that will help it to resist rust.

Wrought iron is tough and durable, but it is expensive.  You can find wrought iron trellises here on the Rustic Garden website.  You can also https://www.etsy.com/market/wrought_iron_trellisfind wrought iron trellises on Etsy.

Stainless Steel

Stainless steel, like wrought iron, is a heavy material for a trellis.  It will hold lots of weight, but it will be difficult to move a steel trellis.

According to Wikipedia, stainless steel is an alloy of steel (iron and carbon) together with chromium (at least 11%).  Chromium helps to prevent rust (iron oxide) from forming on stainless steel.

As with wrought iron, stainless steel is expensive.  You can find stainless steel trellises here on Gardener’s Supply Company.  You can also find stainless steel trellises on Wayfair.

Copper, Bronze, or Brass

Copper, bronze (an alloy of copper and tin), and brass (an alloy of copper and zinc) are good options for a metal trellis.  Copper does not form rust (you need iron to form rust, or iron oxide!)

However, copper does corrode (or “tarnish”) and turn green over time as it oxidizes (reacts with oxygen in the air).  Bronze and brass will resist corrosion better than copper.

You can buy a ready-made copper trellis here on Etsy.

If you know a plumber (or are a plumber) and like to build things yourself, you can try this copper pipe trellis project from Fine Gardening.

If you have some copper pipe scraps, you can try to build your own trellis.

Copper, bronze, and brass are less dense than iron or steel, but they are still heavy.  They are ideal for a long-lasting trellis that will serve as a unique feature in your garden.


Aluminum is a much lighter metal than iron, steel, or copper and its alloys.  As such, it is easier to work with aluminum, and to move a trellis made from this material.

Aluminum does not rust (there is no iron in it to form iron oxide!).  However, aluminum does corrode as it reacts with oxygen in the air over time.

The aluminum oxide that forms will protect the aluminum underneath from further damage.  However, you can get find aluminum with a special clear coating protect it from corrosion.

You can buy a ready-made aluminum trellis here on Etsy.

You can also order a custom aluminum trellis here on Garden Metalwork.

Aluminum is a great choice if you want a long-lasting metal trellis that is light, just in case you want to move it later.

Plastic (Including Vinyl)

If you want a lightweight trellis that will hold up against the elements, then a plastic trellis is probably the best choice for you.

plastic trellis
You can make a custom plastic trellis out of vinyl boards after cutting them to the length and width you need.

Plastic does not rot like wood, and it does not rust or corrode like metal.  It is not too heavy, so it is easy to move a plastic trellis, or to build one on your own.

Vinyl is one of the more common types of plastic that is used to build trellises.  Plastic is a common material, so there are plenty of plastic trellises available online.

For example, you can buy a vinyl lattice panel trellis here on Wayfair.

You can also opt for an expandable plastic trellis, like this one from Kinsman Garden.

Recycled Material and Junk

The recycled material and junk category has its own place, for two reasons.  First, some of these trellises are made from one or more materials, so they defy categorization.  Second, you can find many of these recycled materials for cheap or free!

Construction Materials

Are you doing home renovations, or do you know someone who is?  Ask for anything that can be used as a potential trellis (or part of a trellis) for your garden, including:

  • Door frames
  • Window frames
  • Support beams
window frame
You might be able to re-purpose that old window frame as a garden trellis!

Just make sure that the materials you set aside are non-toxic.  Treated wood, lead, and so forth are hazards that are more likely to appear in older homes.

Wire or Twine

If you have some old fishing wire, metal wire, or twine lying around, then you can use it as part of your trellis.  You can easily make a grid pattern with any of these materials (almost like a rope ladder).

jute twine
Twine is one good option for making a lightweight lattice pattern to act as a trellis.

You can also drive stakes into the ground and run a length of wire or twine between the stakes at varying heights.  This will give your plants several different “levels” to climb as they grow.

A ready-made variation on this idea is chicken wire or rabbit wire.  These materials are often used for cages or fences to keep animals in.  However, you can use them for gardening if you have some leftover material, or if you want to recycle fencing that you have lying around.

You can also use a fishing net as a trellis.  A fishing net has a ready-made lattice pattern, and would be perfect for climbing plants and their vines.  Ask a fisherman who needs to buy new nets if you can recycle the old ones for gardening.


Are you annoyed by the sticks in your yard and garden after a heavy snow or strong wind?  Well, don’t be!

You can use the sticks to build a trellis.  Look for long, tall, straight sticks to build the vertical and horizontal pieces for a grid trellis.

You can also drive sticks into the ground and run a length of wire or twine between them at varying heights, as mentioned earlier.

A variation on this idea is to use an old ladder as a trellis.  Just lean it up against a wall or fence (or open up an “A-frame” ladder and put it anywhere!)  Then you can let your plants climb up the ladder freely.

Different Types of Trellises

Now that you’ve chosen a material, you need to choose the type of trellis to buy (or build).  There are lots of options, and some are easier to find (or make) than others.


An A-frame trellis is just what it sounds like.  It is shaped like a capital ‘A’, and it touches the ground on two sides.

This gives an A-frame trellis more stability against wind and heavy plants than a vertical trellis.  The best part of an A-frame trellis is that plants can grow up both sides of the trellis.

Alternatively, you can start plants on one side of the trellis and let them grow all the way up to the top.  They can then start working their way down the other side.

The plants growing up an A-frame trellis will provide some shade underneath the trellis.  This can be the perfect place to put shade-tolerant plants (as long as they don’t grow too tall!)

You can see an example of an A-frame trellis from Walmart here.


These are sometimes called tomato cages, but you can use them to support any plant that climbs.  Usually, these are either round or square, with 3 or 4 stakes that you can drive into the ground to secure them.

pepper in cage
Tomato cages can be used to support any plant, not just tomatoes (here a pepper plant is shown growing inside the tomato cage).

Just pay attention to the height of the plants you are supporting with a cage trellis.  Many cages are only 3 or 4 feet tall, while many plants (including indeterminate tomato varieties) will climb much taller than that (easily 6 feet or higher).

You can find tomato cages from Gardener’s Supply Company here.


A fence trellis is just what it sounds like: it has a lattice pattern and looks like a fence.  A fence trellis will need some kind of support to keep it standing, especially in windy areas.

chicken wire trellis
A fence made of chicken wire or chain link can be used as a trellis to support your plants.

There are many options for a fence trellis if you buy one ready-made.  For example, you can buy a trellis made of willow saplings from Home Depot.


An obelisk trellis is often round, similar to a tomato cage.  However, they tend to be taller than tomato cages, and the vertical supports meet in a point at the top of the obelisk.

Wayfair has a steel obelisk trellis set available here.

Trellis Height and Alternatives

If you are unsure about how tall to make your trellis, I go into detail about it in this article.

If you like the idea of using trellises to decorate your garden while allowing plants to climb, then you might want to check out pergolas and arbors as well – you can read more about them in my article here.


Now you have some idea for the materials you can use for a trellis, and when it might be best to use each one.  You also have some ideas on what shape your trellis might take.
