Plant them in the ground instead of leaving them in their packages to cook on the driveway.
Seriously, their are books on rasberry and blackberry culture. I had some diagrams that showed same "T" supports that looked good. I think you want to avoid letting them get all in a tangle.
Lots of people on this board know a lot about it. But leaving them on the hot driveway to "cook" is NOT the way to go. That's what happened to mine.
“Plant them in the ground instead of leaving them in their packages to cook on the driveway.”
I will definitely follow your advice.

I cooked mine in the garage ... you can do that in Louisiana. The leaves were blanched out entirely white, but I planted them anyway. They actually turned green and the plants grew.
Some things do well in spite of me!
