The passion post

It's the Labour Day holiday in Brisbane.  Beautiful clear blue sky and 24 degrees.  May to September is just great weather here...pity the daylight hours get short.

Anyway, a boring post about this plant:

We have a yellow passionfruit vine growing out of a not very big pot, over an arch that' only about 1.5 m wide.  It is about 2 years old and has produced fruit before, but at the moment, it has gone berserk.   I reckon there are about 35 fruit coming on this  rather small area vine which we basically ignore, apart from watering in dry weather.

I have no idea what will happen if I actually fertilize it.  Or should I just let a happy plant be?
