tuberlet revival (was Arisaema hybrids)

[Adam Fikso]

Too dry seems quite likely.  My other thought is that they may do better
with more light to initiate the chemistry that enables them to grow roots.
The fading without rotting sounds like dryness to me, but it could also
include a "dry rot" that you don't see, like a premature senescence.

What's coming up for me this week and last seem to be fargesii and some not
fully identified Chen Yi things that are either concinnum or consanguineum.
Three weeks ago some asperatum came up.  Haven't seen candidissimum.
Sikotak and sikokianum were up about early May.

Was hoping to see nepenthoides this week, and/or dahaiense.  Regards,
Adam
