Dragon fruit (from the genus Hylocereus), also known as a pitaya, is a member of the cactus family and native to Mexico and Central and South America. The fruit of the cactus is known as dragon fruit, and it is red with large, green or red scales scattered along the surface. Dragon fruit has served as an important food source for indigenous people for centuries and is an important export in Vietnam, according to horticulturists with the University of Florida. Dragon fruit seeds germinate quickly and are easy to get started.
Mix equal parts of potting soil and perlite and pour it into the seeding tray to within 1 inch of the rim. Add a 1/4-inch layer of perlite over the top of the soil, but do not mix it in.
Place the seeds, 1/4 inch apart, on the perlite layer in the seeding tray. Place a layer of perlite over the seeds (just enough to cover them).
Use the misting bottle to mist the seed bed with water. Give it enough water to moisten the bottom layer of soil.
Cover the tray loosely with plastic wrap and place it in an area that is out of direct sunlight. Check the soil periodically to make sure that it isn't drying out. If it has, mist it lightly with water. The dragon fruit seeds should germinate within a week.
Move the seeding tray into a brighter area when all of the seeds have sprouted. Allow the seedlings to get two hours of morning sun for one week. Gradually increase the seedlings' time in the sun over the next two weeks. Keep the soil moist by misting it with the misting bottle.
Thin the planting bed when the dragon fruit seedlings are 3 to 4 inches in height. Remove and dispose of any seedlings that are smaller than the others.
Pour equal parts of potting soil and perlite into 3-inch pots. Carefully dig out the seedlings and plant them in the pots, covering the roots with soil. Handle the roots as little as possible.
Place the pots in the same amount of morning sun that they were receiving while planted in the tray. Leave them in the sun for one hour more every day until they are growing in full sun.
