I planted the vine in Autumn last year. It grew profusely and had plenty of flowers which turned into fruit this year.However on cutting a ripe fruit open,it was lined with a thick layer of white pith and the seeds all dry and under-developed with no juice.I fertilised it with Dynamic Lifter.What have I done or not done to cause this?

How disappointing to see your vine growing profusely only to produce fruit that is not edible. What you have described is called 'Woodiness of passionfruit'. This is a viral disease that has been carried principally by aphids. As you have mention. when you cut through the fruit, you will notice a thick rind and a small pulp cavity. All you can really do is to keep your vine healthy by making sure it receives plenty of sunshine, fertilise and water on a regular basis. In spring, when the vine is flowering, you may need to spray with a Yates Pyrethrum Insect Pest Killer Concentrate spray to control any aphids that may be present. Good luck for next season.
