Over the past few years, my Passiflora caerulea has developed severe
chlorosis - it looks just like magnesium or iron deficiency on an
cacifuge plant, but P. caerulea is not one such. Has anyone got
any ideas?

I have given it a foliar feed and watering with a mixture of Epsom
salts and Miraclegrow ericaceous, but neither have worked very well
before.

I also have two out of 3 Cistus cuttings in small pots with the same
problem, and have given them the same treatment.

There is a new virus called Passiflora chlorosis virus, but why
should it have appeared, and is anyone familiar with what it looks
like? I can't find a picture.

Nick Maclaren.
