Hi Bob, One thing that has worked for me is to bisect the bulb, saving the larger half to plant (after treating with fungicide) and chipping the smaller portion. The chipping protocol also involves fungicide. The main advantage is you will likely get a bloom to pollinate from the larger half without skipping a season, but you still have the same risk as with chips alone regarding infection. I would leave the roots on the half you don't chip. I wouldn't risk twin-scaling alone until you get good results from chipping. Another protocol I saw involves less trauma. Remove the roots and do a tic-tac-toe saw cut through the basal plate up into the scales a fraction of an inch and set the bulb on its side in a dark place. Bulblets will appear in each segment over time. Hope this helps, Tim On Fri, Dec 1, 2023 at 9:41 AM Robert Lauf via pbs < pbs@lists.pacificbulbsociety.net> wrote: > Does anyone have a recommendation for vegetative propagation of > Hippeastrum?
