Hi
Only have the ornamental types ,a red and a purple.Have no idea which types.Both grow at unbelieveable speed.
For the red I'd suggest pruning every other day lol.
It is beautiful but soooo invasive . Can't help with the edible kinds as I only grow useless plants for some reason, lol gary

Thanks. I think I'm going to cut them hard back. They are such vigorous plants I'm sure they'll resprout. How long can you expect a passion flower to live on average? Or are they just old soldiers...?

Once again, I'm green with envy! :> I have a passiflora decainsea (sp?) that is barely clinging to life at the moment. The poor dear is not happy about the drafty cold room we are in right now. But, it's not dead yet! I pruned off the dying main stem, and it's still slowly turning brown. : Hopefully in my next life I can be reincarnated into a tropical place. :D

I chop them way back when they grow out of control and get on my nerves. I've never had a problem with any of my passiflora putting out new growth no matter if I cut it a little or almost to the soil line. All my passies are grown in containers.

I plan on cutting my passion vines back pretty good this winter so I can clear the fence for next year. I have never had a problem of them coming back although sometimes I wonder. I was just wondering how much water to give them during the winter months so they don't take so long in the spring to start growing?

Unless you are having a severe drought I wouldn't water inground passies at all during the cold months while they are dormant. Cold wet roots promote rot.
