Hi all, Nothing to do with pruning or growing of, but a story.
I had a Passion Flower growing up and over a garden shed, it died, or so I thought,it reappeared the other, more sheltered, side of the shed and has lived there happily for many years. The shed is on a concrete base with a homemade stone filled drain running underneath. The Plant followed the drain. As Tom would say its probably "not unusual"
