Pruning and training Lady Banks on a pergola
Hi. Thanks in advance for any help.
I am a rare Gardenweb.com user, but I know that this is the place for expert advice.
I have a 16' x 16' by 9' pergola which I have planted four Lady Banks, one at each corner (photo below). The goal is for the plants to grow up and cover the pergola providing shade and overall beauty. As the plants get tall enough to pin horizontally across the top I would like to prune them as narrow as possible along the vertical section.
So, two questions:
1) Do I have too many plants, and if so how many should I remove? I think I do have too many, but I'm wondering if I should only have ne or if I should have two.
2) What is the best way to acomplish this?
