I think you're right. About the rotting bulb and scale bulblets.
In my defense, things got moved around more than once over the last few years, meaning my mental map of lily pot locations was terribly inaccurate... and I had thought that somewhere I
did have a pot of very small miscellaneous species bulbs - survivors from a long-ago purchase that I couldn't remember the contents of clearly. I do recall seeing what I thought was this pot in a different place last year, and it had a pair of non-flowering, very short grassy stems... I didn't even bend down to examine them... I just thought, 'oh yeah, they must be the survivors from that Marcus [Harvey] purchase' and watered something else instead.
As for the years prior to that... no recollection.
But as we've observed, at least now we know the secret to making
L. cernuum happy. Don't weed and don't water.
Tracey... for every deceased cernuum we have racked up between us... the next ones get ignored and will flourish!
