You can plant it, but you need to be patient, because it takes half a year to germinate. I also discovered it by accident. Don’t follow the method of inserting toothpicks on the Internet. It doesn’t work. Soak the core in water after you eat it. You don’t need to use too much. After soaking for a period of time, there will be no change in the core. Yes, insert it upside down into the soil. I always insert half of it, and then remember to water it. It will sprout in half a year. Two have sprouted successfully. I hope this can help you. I wanted to show you the picture, but I didn’t know how to upload it, so I forgot about it.
