10 kiwi berry seeds. Kiwi berries are vines. They prefer full sun, well-draining soil, and regular watering. Most varieties require both male and female plants for pollination, though some are self-fertile. Pruning is essential to manage growth and encourage fruiting. They take about 3–5 years to produce fruit, with harvests in late summer to early fall. Please note due to the fact the these are seeds we can not guarantee male or female plants.
