If the seeds sprout within a few weeks, it indicates that they are viable and capable of growing into kiwi plants. However, keep in mind that even if a kiwi fruit has viable seeds, the resulting plant may not produce the same type of kiwi fruit as the parent plant.

Kiwi trees are typically propagated through grafting to ensure consistency in fruit quality and characteristics. Nonetheless, growing a kiwi tree from seed can still be a rewarding and enjoyable project, even if the fruit produced may differ from the parent plant.
