3 leaves per Alocasia plant seems sparse
Last summer I picked up a few small Alocasias (Aurora, gageana California, lauterbachiana in 3" pots) and converted them to soil-less media. Had a bit of a time getting the sunlight levels right, and then we had whiteflies and thrips, and then came the fall. Not the easiest start, but they're all doing fine, slowly but actively growing. So far, though, I can't seem to get more than 3 leaves at a time per plant, so that the opening of each new leaf coincides with the demise of the oldest leaf. The A. lauterbachiana produced a pup, but it too has only three leaves.
Is this typical (in which case denser plantings could solve the "problem")? Or, is it typical of young, or container-bound, or cold, or improperly cared-for Alocasias? I'd like to get a few more species, but more importantly I want to help the ones I have live up to their potential!
