Planting depth for Lycoris

Hi Tony,
That's fascinating! I hadn't thought of Zephyranthes buds forming and then
sitting dormant until conditions are right, but it makes perfect sense.
How else could they appear so quickly after rain? It seems reasonable that
Lycoris might do the same thing.
Only one of my four clumps of L. x squamigera bloomed this year, which
isn't too far off their usual production, but my L. longituba bulbs--which
had been very reliable--didn't have a single inflorescence. Until I see
some foliage, I will be worried that they rotted in the wet weather. Most
of my L. x squamigera originally came from a patch that my wife's
grandparents planted in Pennsylvania, probably more than 70 years ago. I
doubt if it has been thinned or replanted since then. The house is still in
the family, but we rarely visit at the right time of year to know how well
the bulbs flower. I guess I should ask.

Hi Nick;
This brings up another puzzling lycoris issue. Everything I’ve ever read
has repeated that Lycoris x squamigera flowers only after a very cold, long
winter, which is why it flowers reliably in cold climates, but not in
warmer regions...Bill suggested that our long, cool spring in 2020 caused
the buds to break, despite the mild winter temperatures. Others have long
linked rainfall with lycoris flowering, which is certainly the case with
zephyranthes. Sounds like a great grad student project.
