I have a male and female kiwi vine. Both have been in the ground for 6 years and were a year old when planted. The male has been blooming anually for 3 years and is covered with blossoms. The female has nevedr bloomed. The male plant is more vigorous than the female but both plants are in the same soil, get the same fertilizer, water etc. How can I tell if I in fact have a female kiwi vine (it was bought as one) and if so how can I get it to bloom? Hope someone can help. Thank you.
