How to Build Raspberry Trellises (3 Simple and Effective Ideas!)

Growing raspberries requires more than just planting them in the ground.

For healthy, productive plants, a proper trellis system is essential. Trellises provide support for the raspberry canes, helping them grow upward and preventing them from sprawling out of control.

With the right trellis, you’ll also make harvesting easier and improve airflow, reducing the risk of diseases.

In this article, I'll walk you through three simple and effective raspberry trellis designs. Whether you’re looking for a basic setup or something more durable, these ideas will work for gardens of all sizes.

From a simple ladder shape to wire posts and even stakes with wire, we’ve got you covered.

Let’s get into each option and find the best solution for your raspberry patch.

1. Simple Ladder Shape Trellis

A simple ladder shape trellis is a straightforward, easy-to-build support structure for raspberries.

It has vertical supports (acting like the “legs” of the ladder) and horizontal crossbars (the “rungs”), providing a stable framework that encourages the raspberry canes to grow upward rather than sprawling on the ground.

This design is ideal for small gardens or for gardeners who prefer a simple, efficient solution. It also helps keep the raspberry plants organized, improves airflow, and reduces the risk of disease.

How to Build a Simple Ladder Shape Trellis

Building this trellis is an easy project that even beginners can complete with basic tools. Here’s how to do it step by step:

Materials Needed:

• Cordless drill and jigsaw (for cutting and assembling).
• Wooden stakes or similar vertical posts (to act as the “ladder” supports).
• Post anchors (to secure the posts into the ground).
• Crossbars (for horizontal support).
• Screws, wire, string, or clamps (to attach the crossbars and secure the structure).
  

Steps:

1. Prepare the Raspberry Bed
   
   Start by preparing the bed for your raspberries. Clear a space of approximately 3 x 0.5 meters where you’ll set up your trellis. This will give the plants room to grow and spread out.
   
   
2. Install Post Anchors
   
   Place three post anchors evenly spaced at a distance of about 1.5 meters apart along the length of the trellis. These anchors will hold the vertical posts in place and provide the stability needed for the structure.
   
   
3. Cut the Square Timbers
   
   Using a jigsaw, cut square timbers (or similar sturdy materials) to about 1.8 meters in length.
   
   You can adjust the length depending on the type of raspberries you’re planting. For smaller varieties, you may want to shorten the timbers slightly.
   
   
4. Secure the Vertical Posts
   
   Insert the cut timbers into the post anchors, making sure they are standing straight.
   
   Use a cordless drill to secure the posts tightly into the anchors, ensuring they are firmly held in place. The posts should be deep enough in the ground for added stability.
   
   
5. Attach the Crossbars
   
   Once the vertical posts are securely in place, attach horizontal crossbars to the vertical posts at the desired height.
   
   You can adjust the height based on the size of the raspberry plants.
   
   Typically, the first crossbar is placed about 30 cm from the ground, and subsequent bars are added every 30 cm or so. Use screws to attach the crossbars firmly.
   
   
6. Plant Your Raspberries
   
   With the trellis now in place, you can plant your raspberries underneath it. The plants will naturally begin to grow upward along the vertical posts and horizontal bars.
   
   Ensure that you plant them with enough space between each plant to allow for growth.
   

Why Choose the Simple Ladder Shape Trellis?

This trellis design is perfect for gardeners looking for a simple and low-maintenance way to support raspberry plants.

The ladder shape allows for good air circulation around the plants, which reduces the risk of disease and makes harvesting easier.

Additionally, it requires fewer materials and tools, making it an excellent choice for beginners or those working with limited space.

It’s also easy to build and flexible enough to accommodate different raspberry varieties.

2. Wire Trellis with Wooden and/or Metal Posts

A wire trellis with wooden or metal posts is a more robust and customizable option for supporting raspberries.

This design uses horizontal wires or cables to provide the necessary support for the plants, and the posts (whether wooden or metal) act as the base.

It’s ideal for gardeners who need a stronger, more adjustable solution, especially if they’re growing larger or heavier raspberry varieties.

This setup offers more stability and allows you to adjust the tension of the wires as the plants grow.

How to Build a Wire Trellis with Wooden and/or Metal Posts

Building a wire trellis might take a bit more time and effort, but it provides a sturdy, long-lasting solution for your raspberries. Here’s a step-by-step guide for beginners:

Materials Needed:

• Wooden Posts: Two vertical wood posts (e.g., 2x4s or 4x4s), four smaller horizontal pieces for support.
• Exterior Wood Screws (about 2.5 inches).
• Eye Hooks (for attaching wire to the trellis).
• Durable Wire (10-12 gauge, or wire cable if preferred).
• Turnbuckles (optional, for tensioning the wire).
• Post Driver (if using metal T-posts).
• Pipe Hose Clamps (for securing wood to metal posts, if using T-posts).

Steps (Wood Posts Method):

1. Cut the Wood Posts
   
   Start by cutting your vertical and horizontal wood pieces to the desired size.
   
   For taller raspberry varieties, the vertical posts should be around 2 meters high. The horizontal pieces should be cut to about 1 meter in length, and you’ll need at least two for each side of the trellis.
   
   
2. Attach Horizontal Support Bars
   
   Secure the horizontal support pieces to the vertical posts using screws and wood glue.
   
   The first horizontal piece should be placed about 1 meter above the soil, and the second piece can be positioned about 60 cm higher, depending on how tall you want your trellis.
   
   
3. Install Eye Hooks
   
   At both ends of the horizontal support pieces, add eye hooks. These will be used to attach the wire. You’ll need a total of four eye hooks—two on each horizontal support piece.
   
   
4. Set the Posts in the Ground
   
   Install the vertical posts into the ground. Use a post driver to secure the metal T-posts, or dig a hole for wooden posts and fill it with gravel or concrete for added stability.
   
   Make sure the posts are deep enough (at least 60 cm) to prevent the trellis from tipping over as the plants grow.
   
   
5. String the Wire Between Eye Hooks
   
   Cut a length of wire long enough to reach from one eye hook to the other. Thread the wire through the eye hooks and secure it tightly.
   
   For stronger support, you can use wire cable and a crimping tool to attach it securely to the eye hooks. If you want to adjust the tension, consider using turnbuckles between the eye hooks.
   

Steps (T-Post Method):

1. Install T-Posts
   
   Place one 6-foot T-post at each end of the trellis line. Use a post driver to secure them firmly into the ground.
   
   
2. Attach Horizontal Support
   
   Attach horizontal wooden supports between the T-posts using pipe hose clamps. This will create a frame to hold the wire.
   
   
3. String the Wire
   
   Run durable wire across the horizontal supports, securing it with the eye hooks, as in the wood posts method.

Why Choose the Wire Trellis with Wooden and/or Metal Posts?

A wire trellis offers excellent support for heavier raspberry varieties, making it perfect for those looking for a more durable, long-term solution.

The flexibility to adjust the wire tension allows you to maintain a sturdy structure as the plants grow.

It’s also customizable, letting you choose between wooden posts for a natural look or metal posts for extra strength. This option is ideal for gardeners who want a more permanent, reliable solution that will last for years to come.

3. Simple Stakes and Wire Trellis

A simple stakes and wire trellis is an easy and budget-friendly way to support your raspberry plants.

This method doesn’t require much more than a few tall stakes, durable wire, and a little effort to set up.

The design works by driving stakes into the ground along the raspberry bed and then running wire horizontally between the stakes.

This setup allows the raspberry canes to be contained within the structure, helping them grow upright while keeping them organized.

The beauty of this design is its simplicity. It’s perfect for small gardens or areas with limited space, as it doesn’t require any complex structures or large posts.

Additionally, the wire system is easy to adjust as the plants grow, making it a flexible solution for those just starting out in gardening.

How to Build a Simple Stakes and Wire Trellis

Building a stakes and wire trellis is one of the easiest and most cost-effective ways to support raspberries.

This method doesn’t require heavy tools or a lot of time, so even beginner gardeners can handle it. Follow these steps to set up your trellis:

Materials Needed:

• 6-foot tall stakes or posts (wooden, metal, or bamboo, depending on availability).
• Wire (10 or 12 gauge galvanized wire works well).
• Mallet (for driving the stakes into the ground).
• Old carpet or cardboard (to outline the raspberry bed, optional).
• Pruning shears (for trimming the raspberry canes).

Steps:

1. Outline Your Raspberry Bed
   
   Before installing the stakes, mark the area where you’ll plant your raspberries. You can use old carpet, cardboard, or even string to outline the bed.
   
   This helps you visualize where the stakes will go and ensures your plants have enough space to grow.
   
   
2. Install the Stakes
   
   Using a mallet, drive the 6-foot stakes into the ground at each of the four corners of the raspberry bed.
   
   If your bed is longer than 6 feet, add stakes halfway along the long sides to provide additional support. The stakes should be driven about a foot deep into the ground to ensure they’re stable.
   
   
3. Attach the First Wire
   
   Once the stakes are in place, take your wire and stretch it horizontally between the stakes, about 18 inches from the ground.
   
   You can tie it loosely to the stakes or use clamps to secure it in place. The wire should be taut, but not overly tight—just enough to hold the raspberry canes in place.
   
   
4. Add a Second Wire
   
   Stretch another length of wire at the top of the stakes, roughly 5 to 6 feet from the ground. This second wire will provide additional support as the raspberry plants grow taller. Again, ensure the wire is taut and securely tied to the stakes.
   
   
5. Tuck Raspberry Canes into the Wire
   
   As your raspberry plants begin to grow, carefully tuck the canes into the wire frame.
   
   You don’t need to tie the canes to the wire—simply guide them so they grow along the structure. The canes will naturally follow the wire as they grow.
   
   
6. Prune Regularly
   
   Prune your raspberry canes to about 6 feet in height to encourage healthy growth and fruit production.
   
   Make sure to trim any dead or weak canes, and regularly tuck new growth behind the wires as it appears. This will help maintain a neat and manageable trellis.
   

Why Choose the Simple Stakes and Wire Trellis?

The simple stakes and wire method is an affordable and straightforward solution, making it ideal for beginner gardeners or those with limited space.

The design is flexible, allowing for easy adjustments as the plants grow. Since it doesn’t require large or heavy materials, it’s a great option for small gardens, raised beds, or even against a wall.

Additionally, this system provides just enough structure to keep your raspberry plants contained without being overly complicated, making it perfect for those looking for a hassle-free solution.
