1. Cut the pitaya in half, and gently scrape the pulp into the container with a stainless steel spoon.

2. Dilute the pulp with water and gently rub it with your fingers to separate the pulp from the seeds as much as possible.

3. Pour the pulpy pulp into the short stockings and continue rubbing for a few times. Then soak in water 1 day for no more than two days, or it will germinate. Continue rubbing the next day, so that all the pulp is squeezed out, leaving only black seeds, which look a bit like black sesame seeds.

4. Lift the stockings and drain. You can use toilet paper to dry the water on the seeds, take out the seeds and lay them flat on the plate. Blow gently with an electric fan to make the seeds completely dry and separate from each other, and then you can start planting.

5. Choose a suitable pot without a hole, or fill the hole with a pot with a hole, put it in sterile culture soil, spray some water to make the surface soil very wet, and then spread the seeds evenly on the culture soil.

6. After spraying water on the seeds several times, wrap them with plastic wrap to keep the surface moist, then open them and spray them once a day until new buds grow.

7. After a week, the whole basin surface will grow, about 1 cm high. The seed shells will fall off one by one, and the whole pot will feel green, thriving and full of green.

8. After two weeks, it grows taller, about 2 cm high, and the leaves are more compact and thicker. The color of the two leaves turns yellow-green, which is very suitable for placing in the office or living room, and has a refreshing and comfortable feeling.

9, about four months, the second level will start to grow like a cactus thorn.
