Gardening Questions SOME KIND OF BERRY VINES?

They could either be Blackberries or Loganberries. They flower on wood produced last year. so if you leave them alone now, they should be ok for next season. Then after fruiting, you cut off the canes which have fruited and tie in the new ones for the follwoing year.
6 months? Gosh you have done a tremedous amount. I am totally impressed.

Have a look on this webpage, very good photo's of blackberry leaves and I think they are different from your photo.

Looks like a cane fruit of some sort, the growth it makes this year will fruit next year, the canes can get very long. Train them where you want them the leaves drop then sprout again in spring, if you cut them down again this autumn you will sacrifice next years fruit, In spring mulch with compost and keep well watered and you will have lots of lovely soft fruit next year. It could be a tayberry or a cultivated blackberry, loganberries are thornless. To make new plants pin down the tip of the cane on the soil and it will root

loganberries are thornless
Sorry, but whilst there is a thornless variety of Loganberry, they are most definitelt THORNY! Indeed there are thronless varieties of Blackberry.
In both cases they can and do produce extremely thorny shoots too.

Thank you for the ideas, I guess we will wait until next year to finally know. They are so tall, so I think I will pin most down.
