1. Leave the black seeds of the dragon fruit and soak them in tap water. After 24 hours, take them out and place them in a cool place to dry.

2. Place some gravel on the bottom of the flower pot, fill it two-thirds of the way, and spread the seeds evenly in an even layer. Then spread a thin layer on the seeds and use a watering can to spray water on the dragon fruit seeds.

3. Wrap the mouth of the flower pot with a layer of plastic wrap, then place it on the windowsill to receive light.

4. Open the plastic wrap and spray water on the dragon fruit to moisturize it every day. The dragon fruit will sprout in about a week. If you spray it with water frequently to moisturize it, it will not take long to grow into a small green potted plant.
