Answer 1

A soil test may help determine if certain nutrients are lacking. You can get one at your nearest Extension office. Passion vines are considered heavy feeders so I don't think the compost was a problem. Have you fertilized any other times? Here is an article on fertilization and also on leaves turning yellow. Hope this helps.
