I have recently purchased a climbing hydrangea. I would like some advice on how to plant. I would like it to grow up some bamboo I have attached to the side of a garage. The plant came with a supporting cane. I was advised that these plants support themselves but I was just wondering do I need to train it to climb up the building or lean it towards the building in any way? Should I remove the original supporting cane that the plant came with? And how far away from the building should I place the plant? Thank you in advance.
