I am new to vines. Yes yes, thank you, I am excited too. I have planted three different vines to cover some lattice work that is-crossing my fingers-going to be shade for our patio this next hot az summer. My question. How do I get my vine to grow in thick? We have about three long lines that are growing like crazy. They-and only they-have reached the top of the house. Should I cut them back? How do I promote fullness?

Thank you for helping thie vine-ignorant person!
