I'm aware of that but that's not going to happen in a container is it.
The plant has only just been purchased and the reason it's a foot or so tall is because the 3 stems have been cut by the grower (a recommendation anyhow on planting apparently).
Perhaps I'll build a bamboo fan then for the pot if they really have to be trained like that in pots.
Blackberry plants are large ... they cannot be kept small ... how had you thought you were going to grow them ... when you bought them did you visualise the space they would ultimately need? Did the seller provide you with appropriate information?

All turning unnecessarily confrontational...when all it has to be said is that most blackberry varieties are not suitable for growing in containers due to their vigour and need for feeding. It's that simple. But since you have the plant @pierre_de_gaye you may as well give it a shot and see if you get any fruit. But it may well be a newer cultivar that can be grown successfully in a container like this one: https://www.rhsplants.co.uk/plants/_/blackberry-purple-opal/classid.2000028534/
Not confrontational simply trying to see if the OP has mistaken or been misled about its requirements. If it’s not what he wanted I would suggest he returns it or exchanges it for something he has the space for ... that’s all 😊
I get a bit annoyed by the misleading way some suppliers describe their plants and the space/size of container needed.

Ok then, Dove - you clearly want me admitting that I got it wrong on this occasion, so I will do so if it makes you feel better. Have you never made purchases in error yourself? I was only going on what I'd read and the fact that merton thornless was supposedly a really good one to go for. It appears that the people who recommended it for containers obviously didn't know what they were talking about then.
I'll now have to go and order something like Loch Ness. Apparently it is self supporting, compact and good for containers. If this doesn't meet your approval, please say so before I make a second purchasing mistake.

It's a Merton thornless and I'd read that these are in fact suitable for container cultivation.
One of the country’s pre-eminent fruit growers states that they need a lateral space of around 8’ to train the canes on wires.
