I've successfully (so far) over-wintered my passion flower vine indoors and have also established 3 new plants from cuttings last fall. Last summer, the vine grew to over 30 feet up a wall on a west-facing deck, but produced very few flowers. I found conflicting information on how often to fertilize. Does anyone have advice for how to prepare the plant for moving outdoors (re-pot??), and how to coax more flowers throughout the summer? Thank you!
