Kiwi fruit form on the current seasons growth...ie: the
shoots/canes that form during the current spring. Hacking the vine
off at ground level is probably going to be fatal (to the plant).
Male and female flowers grow on different vines the problem being
the female flower has no nectar and bees show little interest.

Asearch in 'google' will also bring up numerous good sites with
more info.
