Sandy, unless youre planning on doing cross-pollination experimentation, I would avoid growing from seeds. I would almost say don't do it. Not only are you going to add years to your wait for fruit production, you're also going to be playing roulette with the type of fruit you get when the plant matures. The preferred method for reproducing dragon fruit is from cuttings for a reason: you know exactly what youre going to get, a copy of the plant the cutting came from. Seeds have a random chance of picking up traits, both good and bad, from their parent plants. And if you self-pollinate, theres a chance you can come up with weak or genetically inferior stock. Self-pollination is fine for fruit production, because we're eating the flesh of the plant, basically the unaltered womb of the mother plant, but the developing seeds (aka offspring) can still end up undesirable. However, if you do plan on trying your hand at finding new varieties, wash your seeds, dry them and store them in an air tight container, preferably with one of those Silica Gel packs that come in packaging, the ones that say "Do Not Eat" on them. This will keep your seeds dry for storage.
