There aren’t many things quite as satisfying as biting into a juicy blackberry on a warm summer day.
Packed with edible seeds and offering a sweet and tart flavor, these deep purple berries are a must-have summertime staple that can brighten up your salads, cocktails, and even your breakfast oatmeal.
To be able to eat them, you must plant them. Do Blackberries Need a Trellis? Some breeds require a trellis to help support the vines.
Blackberries contain high levels of antioxidants, including vitamin C, vitamin K, potassium and fiber. They are generally very low in fat and zero saturated fat.
They contain a small amount of protein, but most of the calories come from carbohydrates.
Blackberry cultivars are generally classified according to their growth habit.
However, there are several factors to consider when choosing a blackberry plant, including choosing between thorny and thorn less blackberries, as well as flowering or primrose fruiting blackberries. common types of bramble plants.

1. Upright growth habit
Blackberry plants with an upright habit form erect branches that do not require a trellis. There are varieties with thorns and without thorns.
Popular upright cultivars include :
Navaho,Natchez,Ouachita,Apache,
Arapaho,Prime-Ark Freedom and Kiowa berries.
2 . Semi-upright growth habit
Semi-erect blackberry plants produce erect canes that require trellis for support. Within this broad species there are also thorned and thornless varieties.
Semi-erect blackberry plants tend to be sturdier than upright varieties. Wild blackberries (also called brambles) belong to the semi-erect category.
Popular semi-upright cultivars include:
Chester and Triple Crown blackberries.
3. Creeping habit
Blackberry bushes with a creeping habit need a trellis to support their sprawling shoots. These strains do best in warmer climates and produce very heavy yields.They must be provided with a trellis.
What is the best way to support blackberry bushes?
As mentioned above, creeping blackberries need a trellis or support.
In smaller spaces, garden arches are a great solution as they offer a very large growing area while taking up very little space on their own
Traditionally, three different training methods are used to support blackberries and their hybrids, these are the Rope, Fan and Weave training methods.

Rope Method
This is the easiest training method, but not the most productive as the poles are tightly packed and the leaves can shade each other.
In this system, new sticks (primocane) are tied vertically or wrapped around the bottom wire. Although this method is less labor intensive, it requires much more handling of the sticks, so gloves are required to avoid thorns!
Fan Method
This training method provides high yields, but is labour intensive, and is recommended for less vigorous varieties (such as the compact and thornless varieties).
With this system, fruiting canes are tied to both sides of the trellis in an arching fan shape, and new canes (primocanes) are trained vertically, and then tied at the top wire.
After fruiting, the old canes are cut to ground, and the vertically tied new canes are spread and tied to each side to take their place.
Weave Method
This training method provides the highest returns, but requires the most effort!l.
With this system, fruiting canes are woven to both sides of the trellis, and new canes (primocanes) are trained vertically, and then tied at the top wire.
After fruiting, the old canes are cut to ground, and the vertically tied new canes are woven and tied to each side to take their place.
Blackberries only need a little pruning to keep them healthy and happy. Every spring you need to prune the central primocanes of each plant to three to four feet in height.
Modern method: Three-Wire Wrap
A modern, highly efficient and productive method of growing blackberries and their hybrids requires only a three-wire grid.
In a group of six reeds, three canes are bundled together and loosely woven around two top wires, one on each side of the trellis.
The new canes (primocane) are braided around the bottom wire to separate them from the fruiting rods on the two top wires
This will encourage the plant to focus its energy on growing side shoots. But you will also need to cut them back, to about 30cm in length.
Loosely tie the oldest fruit canes (floricanes) together near the base. After fruiting, cut off the canes tied in a bunch on the ground.
Then unwrap the younger primocanes from the bottom wire and wrap them around the top wires to take their place

Do I need a trellis for blackberries?
All blackberries are perennials;the roots survive year after year. The above-ground plant, however, is what is called a biennial. This means that the canes will grow vegetatively for one year, bear fruit the following year, and then die.
Regardless,the plant sends out new canes every year to replace the dead ones.
Blackberries are enthusiastic and vigorous plants, so make sure they have plenty of room to grow. As the stems grow they will also need support in the form of sturdy wires or a trellis.
Creeping blackberry plants have trouble staying erect because of the sheer weight of their stems. The trellis makes sure that the fruits last till they are harvested by protecting them from soil moisture,insects and trampling.
The best fruit-bearing blackberry bushes will require a trellis.
Another reason why your blackberry plant needs a trellis is, if the canes rest on the ground, they will root into the soil and a new plant will emerge with its own roots and vines from that point.
How do you make a trellis for blackberry bushes?
This is an inexpensive way to grow thornless blackberries in the garden.
Construction of a trellis for blackberry plants requires little.
To build your own trellis, all you need is a few DIY materials that you can get at any hardware store. If you already have the posts, you can order the other items online if you want.
- Wood screws
2. heavy-duty garden wire
3. 4 by 4 wooden posts about 60 inches long and
4. eye bolts
These are all you need to build a simple blackberry plant trellis.
Painting the wood is optional, but you can extend the life of your posts if you take the time to do so. The eyebolts used should be suitable for outdoor use and have an eye large enough to pass two wires through.
If you don’t have these on hand and want to save money, you can use regular screws and wrap the wire around them.
In case you are wondering what are the benefits of vine screws over regular screws,they space the wire away from the wooden post, allowing more room for the sticks between them. If you use screws, the canes will be bound against the post and could rub against it in the wind.
All the same, it is not a deal breaker and you can choose any one.
It is advised that you use 2mm or thicker garden wire. If you use thinner wire, you risk sagging or breaking the wire when the canes are full of leaves, flowers, and berries.
A thicker cable is probably better if it has more spacing between posts,but it can be a bit more difficult to manage.
Constructing the Trellis(7 steps)
- To build the trellis, measure the length you will build the entire structure. Each bramble needs at least two meters on each side to extend its canes.
2. Sink each post two feet into the ground and tighten very securely.
3 . If you want really solid posts, you should think about cementing them.
4. With all the posts in place, screw in the eye bolts. Two go in each post and all must be placed on the same side of the poles.
5. Ideally, the bottom eye bolt should be placed 12 inches from the ground and the top eye bolt ,3 inches from the top.
6. This next step is very important in securing the wire:you can thread a piece all the way to the end of the trellis, but be sure to wrap it around each screw to the end.
7. As the berries grow, make sure the canes grow over the wires. If the canes try to grow along the ground, you can loosely tie them to the wires with loose ribbons or zip ties.
Finally,
Depending on whether you’ve planted erect, semi-erect, or trailing varieties, you may need to grow your vines against a trellis for support.
Blackberries grow in most fertile soils, especially slightly acidic soils rich in humus. Choose a planting spot with good drainage and maximum sun exposure to ensure your berries ripen evenly.
Remember to harvest your blackberries on time,before the birds get to them.
