How to hasten the ripening of kiwifruit?

To hasten the ripening of kiwifruit, you can place them in a paper bag with an ethylene-producing fruit, such as bananas or Apples. The ethylene gas released by these fruits will speed up the ripening process. Additionally, storing the bag in a warm area can further encourage ripening. Check the kiwifruit daily to monitor their progress and avoid overripening.
