Kiwi fruit flower

Our 15 year old Kiwi fruit plant flowers but never produces fruit.

Research now reveals the following from Wikipedia

“Kiwifruit plants generally are dioecious, meaning a plant is either male or female. The male plants have flowers that produce pollen, the females receive the pollen to fertilise their ovules and grow fruit; most kiwifruit requires a male plant to pollinate the female plant. For a good yield of fruit, one male vine for every three to eight female vines is considered adequate. Some varieties can self pollinate, but even they produce a greater and more reliable yield when pollinated by male kiwifruit. Cross-species pollination is often (but not always) successful as long as bloom times are synchronised.”

I am going to use a soft lens brush and try to pollinate some flowers. The problem is that the vast majority of the flowers are very high up on the woody vines that rise up to find the sun.
