  • Question
    My kiwis bloom but they fall off. What can I do?

    Community Answer
    In order to get fruits, the female kiwi plant needs to be pollinated by a male plant. The latter never bears fruit. In general, a ratio of at least 1 male plant for 7 female plants is recommended. There are also kiwis that are self-pollinating, but cross-pollination will most often result into more fruits.
  • Question
    Do kiwi vines die down in the winter to just sticks?

    It is deciduous, so the leaves fall off in late fall, but will leaf out again in the spring.

    How do I tell a male plant from a female plant?

  • Question
    Is it possible to grow the tree inside to protect it from bugs outside that eat plants?
    Community Answer
    Kiwi has very few if any insect pests. As far as growing inside, I'm assuming you're talking about a greenhouse. It would have to be a huge space because it grows so fast. It is not a house plant.
  • Question
    My vines bloomed with tiny fruit but the fruit is already beginning to wilt and die. Last year was the first time they bloomed with only a few tiny fruit that didn't mature. Is this normal? Any suggestions?
    Community Answer
    This is totally normal. Wait a couple more years and bring it in if it gets cold. Water it about once every week. If it does not start to bloom in the next 6 months, it probably won't grow.

  • Question
    How do I know if I can grow kiwifruit in my area?
    Community Answer
    If you live in the US, you can grow kiwifruit in hardiness zones 7 and 9. If not, you need a frost-free season of 225-240 days since vines leaf out in March, bloom in May, and are harvested in October or early November. Temperatures below 10°F (-12°(C ) in mid-winter will kill all young vines and some old bearing vines. Frost below 30°F (-1°C) in spring will kill shoots and ruin the crop.
  • Question
    What do I do if my kiwifruit is several years old but it still has no blooms?
    Community Answer
    Kiwifruit plants require full sun and appreciate some afternoon shade in hot locations. They also need decently rich soil, regular water, and good drainage. If your kiwifuit is not blooming, it may be due to insufficient sunlight, overly dry soil, water-logged soil, or insufficient nutrients in the soil.

    Half a meter (50 centimeters) would work very fine. That would give sufficient space for the root,s as well as an abundant amount of soil and moisture.
  • Question
    What should I do if the kiwifruit plant I am growing is losing its leaves?
