Kiwi problem

I have 4 Kiwi Jenny plants that are over 5yearsold ,every year full of flowers bees love them but no fruit, please can anyone tell me why no fruit.

I have a kiwi plant too that has not fruited at all dispite all its growth and the fact it is self fertilizing .I am at a loss as well.

I have two Kiwi plants, one male one female which are around 5 years old, they have flowered and fruited a little but last year they surpassed themselves by growing 75 fruit. This year there has been nothing at all, I think it is all to do with the weather.

thank you both for your replies seems I need a male kiwi plant do you know were I can  buy one from?

I had a Kiwi Jenny back in Sydney. It doesn't need a pollinator so your lack of fruit is down to other things. The Sydney climate was perfect - endless warmth. Apart from needing plenty of warmth, they also need to be kept in check, I found. Left to grow with wild abandon they can forget about fruiting.

I purchased mine from a garden centre who sold both male and female plants. I also cut them back quite severely as they put on a huge amount of growth

If c.woodward's plant is indeed a Kiwi Jenny it doesn't need a pollinator.
