10 Blackberry Trellis Ideas (DIY + Photos)


To build an I-trellis for blackberries, you can use any existing fence or sturdy railing. You can also purchase DIY trellis kits at a local hardware store if you have the time and inclination.

If you want a unique, customized look, you can even build it from scratch.

To learn more about different types of trellises, visit the North Carolina State University Cooperative Extension Service website. They have illustrations of various blackberry trellises. They also offer information on how to prune blackberries.

Building an I-trellis is an easy and affordable way to grow blackberries. You can buy all the necessary materials for about $20, and it takes an hour or less to make your own.

When planting your berries, choose a trellis design that allows you to train them to grow in a long row. The spacing between trellises should be ten feet apart because the blackberry vines need space to grow laterally.

Once you’ve positioned the trellis, you can plant the blackberry plants. You can use bare root plants or tie them to the wires of the trellis.

You can plant the blackberries any time of the year. They can grow as high as three feet. However, it is not recommended to grow plants taller than this. If you do decide to grow them taller, you should be aware that the canes may break off in the wind or be damaged by falling trees.

Some blackberry plants do not require trellising, and they may grow on their own. However, in this case, it’s best to build an I-trellis higher than four feet, which will allow the plant to get more sunlight and air circulation.

A 4-foot trellis is not suitable for this purpose, as it might result in a low yield. A higher trellis should be built with 8-foot-long end poles.

They should also be buried at least two feet underground and should poke into sand or gravel. In addition, they can be concreted to ensure their stability in bad weather.

To build an I-trellis for blackberries, you’ll need a few materials and tools. First, you will need some sturdy wooden posts and galvanized wire.

Use heavy-duty galvanized wire for the wires, and space them around fifteen feet apart. Be sure to wrap the wire tightly to ensure that it won’t be loose when the blackberry bramble grows.

Rotating cross arm

A new method for blackberry trellising may increase yields and berry quality while cutting down on labor costs.

Researchers have been testing the Rotating Cross Arm (RCA) system, which may improve productivity by orienting berries in a shaded position and reducing the need for handpicking.

Although no published comparisons of the RCA and standard T-trellis systems have yet been conducted, some growers have reported positive results.

The RCA trellis system was designed to allow growers to train blackberry canes in a specific way. It helps reduce sunscald by allowing growers to place their canes on a horizontal trellis. The system also allows growers to force blossoms onto a trellis to protect the fruit from sun damage.

The RCA trellis is available from a variety of retailers. It is designed to be placed horizontally in winter and rotates to a vertical position once the flower buds open.

Aside from increasing the yields, it helps preserve fruit quality and reduce the incidence of white drupelet syndrome, or red cell disorder. By increasing the amount of Grade-A fruit, this system also increases profits.

A Blackberry trellis is a great way to support canes and prevent fruit from falling to the ground. It also improves sunlight exposure, air movement, and pest control, and makes harvesting much easier.

Once the trellis is established, you can attach the canes and reposition the cross arm as needed. A trellis system also allows you to cover the blackberry plants with a thin polyethylene cover in the winter and remove it in the spring.

The Rotatable Cross Arm trellis system was developed by USDA-ARS scientists at the Appalachian Fruit Research Station in Kearneysville, WV. It is manufactured by Trellis Growing Systems, a partner of the ARS. The RCA system is easy to install and requires no professional training.

The new Rotating Cross Arm is a new design for a blackberry trellis. It uses fiberglass-reinforced plastic components and is manufactured using a pultrusion process. Both arms are secured with detent pins. In addition, both arms are attached to the plates with RCA trellis wires.


If you’re growing blackberries, you may already have a trellis. If not, you can simply purchase a trellis kit at your local hardware store.

Or, you can create your own using a DIY plan. North Carolina State University Cooperative Extension Service has pictures and instructions for making several types of trellises for blackberries.

Pruning blackberries can be challenging, but some people have found success by trellising their plants.

While you can easily build a basic trellis with basic DIY materials, a more complex design may require more skills.

If you’re comfortable doing DIY projects, a bamboo trellis might be easier to build than a wooden one. You can use bamboo poles instead of posts to create a trellis with a square shape.

When choosing the size and spacing of the trellis, consider the size of the blackberry plant. You can plant upright varieties in rows eight feet apart while trailing types should be planted in rows six to ten feet apart.

You should also plant the plants one inch deeper than they were in the nursery. Planting is best done early in the spring, and they need at least one inch of water per week.

Blackberry Oregon Thornless is a popular ornamental variety that bears fragrant, white cup-shaped blooms with a golden-green center.

It has thorn-free stems and produces a heavy crop of juicy, mild berries. This variety grows well in containers and is useful in small gardens.

When planting a blackberry, choose a spot where the plant will receive adequate light. It should also have good drainage.

Water blackberries regularly, and don’t forget to mulch their roots. This will provide additional nutrients and suppress the growth of weeds. You can also use bamboo canes as a trellis for your blackberry.

Birch tree

When you want to grow blackberries in your backyard, you can build a trellis. You can purchase medium-sized trellises from garden centers for reasonable prices, or you can make them yourself for a little more money. Trellises come in many classic and unique designs.

One of the most classic is the square grid design, which promises to be beautiful when the vines have grown over it. If you have the time, patience, and the right measurements, you can make your own trellis.

Another popular design is the V-trellis, which consists of steel posts placed 20-30 degrees off the vertical. This type of trellis is based on the Gjerde system used in Norway.

The posts are moved to nearly vertical during the winter season, encouraging new fruiting laterals on the floricanes.

Trellis for Blackberries: Conclusion

When building a trellis for blackberries, you can tie bare roots to the wires with string, or place a bush near your trellis posts.

You can use a trellis to grow thornless blackberries, which are a common choice because they don’t require additional support.

Once they are planted, they should receive at least an inch of water per week to keep them healthy.

Another option is to build a triangular trellis. This style is a streamlined upgrade of the two-sided trellis and uses similar logic to save space.

Unlike the previous design, this style has wires coming down the pole axis, creating a larger surface for vertical growth.
