Then sit its container in some water to encourage the root growth down to find that water - do not water from above. Colocasias and Alocasias always respond to heat from below too,
but with a 20lb corm that could be unfeasible. Hopefully that will encourage things to begin again with a fresh sprouting from the viable centre of the corm.

1. questions about Amorphophallus titanum (Nancy Greig)

Hello! I just joined the IAS and I am happy to know there is such a
group. Currently we have an
A. titanum about to bloom - perhaps
tonight, finally! We also have a corm (about 20 lbs) of a second plant
acquired in 2006 that just recently went dormant. It seems to be having
some problems - some mushy areas and a bit of whitish fungal growth
on/in the mushy areas. But it is not mushy throughout - the central
portion where the growing tip emerges seems to be fine. Parts of the
bottom of the corm are mushy, and there are some good-sized craters in
the sides. When we unearthed it recently (when the leaf died back) we
found many small snails in mushy areas and also some tiny white insects.
There was an orangish mass of fungus, mushed up corm, and insects on the
sides and bottom when we dug it up. Now it sort of looks like a tooth
with cavities... Is there anything we can do? We would hate to lose
this plant. David Hunt (orchids) told us to spray it with Consan
action 20... Any thoughts? Should we keep it completely out of the
soil (and at what temperature/humidity)? Normally we have left the
tubers in soil in a pot but not watered them for several months while
they are dormant...
Are people familiar with the list of "publicised titan arum blooms" on
wikipedia? I assume someone British (from Kew) puts this together? I
see from the list that several institutions have plants that bloomed/are
blooming this year. It seems that June/July is prime bloom time.
However, as noted our second plant is on a totally different cycle. How
common is this?
Thank you - I look forward to being a member of this group!
