I'm not sure if they use micropropagation or twin-scaling more, or a combo of both, for commercial propagation. I know for hybridizing they have extensive seed operations to grow them out and select the best ones. Here's a good twin-scaling article on PBS wiki. https://pacificbulbsociety.org/pbswiki/index.php/… Modern hybrid Hippeastrums are super-easy to propagate by almost any cutting method. A simple one is just halving or quartering your bulbs, vertically. Think slicing an apple! Each section must have a portion of the basal plate, or course. You can do a version of twin scaling easily at home. I've got resources I'll eventually put on the wiki if you are interested. It's fun, and faster than seed production, and gives you a clone. I know there are PBS members with lots of experience with Hippeastrum hybridizing and propagation. Ken. 1 degree F this morning.
