Feijoa not fruiting this year

Mike J says...
I haven't grown feijoas before but when I hear cases like this, it often comes down to starvation for potassium. Fertilizing with high nitrogen fertilizers will trigger this condition so look for low N combination fertilizers. For the moment, spray the foliage with a quarter teaspoon of potassium permanganate (condys crystals) per 8 litres of water with a wetting agent three times, a week apart. Spread a handful per square metre around the base of the tree with potassium sulphate and water in. Check the pH of the soil and adjust to around 5.5 to 7.0. It could also pay to give your ground a light dressing of trace elements. Obviously, you are not going to get a crop this year, but if you build up the soil nutrients over the next 9 months, you should do much better. Mulching with 25% lucerne chaff to other mulch like wood chips will help in the long term. Never use new wood chips without putting at least 25% by volume of lucerne with it. Lucerne helps the wood chips, or bark chips to break down and helps to prevent fungal root diseases.

I moved into a house many years ago that had a feijoa in the front garden. I had no experience of these and did nothing. It was in poor sandy soil, I never watered it, and it fruited every year - unfortunately loaded with friut fly.

A friend who lives in Donnybrook says they are the easiest plant she has ever grow, needing very litle care. I don't think she gets FF.
