How to Grow Dragon Fruit From a Seed
An easy way to grow your own dragon fruit cactus is by buying a dragon fruit at the grocery store and planting the seeds. However, be aware that if you grow a dragon fruit plant from a seed, it may take several years (sometimes as many as five) before it begins bearing fruit.
Prepare the soil bed. Dragon fruit needs full sun, so choose a sunny area in your garden or a sunny windowsill that gets at least six hours of sunlight a day. For the soil, choose potting soil that is well-draining (dragon fruits are sensitive to “wet feet,” or consistently wet roots) and rich in organic matter. Don’t use cactus soil—as tropical plants, dragon fruits like more water than other cacti and want something that retains moisture slightly better.
