rannvieg, Oh dear, that will take over your greenhouse! You do need to leave the new growth for blackberries next year, cut out the old ones when they have finished fruiting, that will help! I think I am correct here! They look to have thorns too, you might find a thornless variety easier in a greenhouse. My daughter has one, it has very tasty berries.

I grow my grape vine in a 8' wide by 6' deep greenhouse with the roots at the back. I trained a growth to either side, and have steel reinforced plastic washing line strung from front to back tied to stays either end, and one nearer the top in the middle. I also tied more pieces from the sides over the top one to support branches over the top.
