How do you ripen passion fruit? To ripen passion fruit at home, place it at room temperature and give it a few days to ripen further. Keep it away from direct sunlight. Green passion fruit won’t ripen fully off the vine, but ripe fruits will develop deeper, sweeter flavor if left uneaten for several days.
Will passion fruit ripen after picking? Beware – Usually passion fruits take up to 30-40 days to ripen after it picked. But with this method, it will happen much faster. So be careful and don’t let your fruits be rotted.
