Passion Flower Vine
We have a passion flower vine growing on a trellis. The vines have parts that look dry and dead in combination with parts that are greening. Should we prune the dead looking areas? We have had it growing now for about 3 years. Each year it has looked the same, and although there is lots of vine, we don't get many flowers. We live on the south end of Vancouver Island British Columbia.

Add some phosphorus rich fertilizer or bone meal to the soil to help with flowering.
