A. sikokianum

[Danielle]

Carlo,

I have no problems (rot, discoloration or otherwise) with sikokianum.

There has been mention of the importance in keeping tubers dry during
dormancy.

Mine are planted under a large cedar tree, with nice woodland soil.  They
stay dry, unless I water them.
Your area is much colder than mine, which increases the importance of
drainage.  Barry, from Asiatica Nursery, mentioned planting them on a slope.
What about planting deeper?

Occasionally lifting them to check for rot is probably a good idea, though I
haven't done it for a couple years.

Yellow discoloration could indicate the need for a light fertilizer
application.
Black flecks as in rot?  Or just purple coloration?
I have noticed that lean watering during early development causes all kinds
of leaf and spathe disformities.

Ohhh and beware....Slugs LOVE the golf ball tip of spadix...darn things
didn't touch any other part!!!

Does A. sikokianum have any particular problems making it short-lived? I'm
aware of one or two relatively large planted colonies that have been
significantly reduced in size to only a few scattered individuals. Those
remaining show symptoms of a problem in their leaves (some discoloration and
dark flecking). So far in this discussion, no one appears to have kept if
very long.
