I just got a blackberry plant and I'm a bit confused by the instructions I've been finding online. There are a bunch of vines coming from the ground, and then those vines have smaller branches coming off of them. The instructions I've seen are that you're supposed to prune primocane branches to be no longer than two feet long. Does that mean I should be pruning the vines coming from the ground, or only the branches that are growing from the main vine?
And should I be pointing the tips of the plant back into the pot to grow more vines in the future, or will the plant naturally grow more vines?

What blackberry variety is it?
The two foot suggestion would be for the side branches. The main vine generally would be cut between 4 and 6 feet tall. Unless you want to tip propagate them like your mentioned, in which case you can grow it longer and straight into another pot. The vine will recognize the tip is in dirt and start putting out roots. Once it is rooted good you can cut it off and leave a one or two foot length of vine with the new plant, which will grow new vines the next year.
