[Aroid-l] re questions about Amorphophallus titanum

From: Scott Radford <s.rad4d at ymail.com> on 2010.07.21 at 17:18:50(21218) Hi Nancy Welcome the the wonderful IAS from another relative newcomer. I grow mainly Colocasias and Alocasias and some other aroids. From my experiences with similar condition corms of these species to your own then I would try the following: Firstly cut all the mushy infested areas off right back to firm material then treat the corm with a fungicide. I would not leave it in the soil but leave at ambient room temperature resting on top of (or just semi submerged in) DRY compost (I use a peat free growing medium myself) 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. Good luck with whatever you try Scott HTML +More From: "aroid-l-request@www.gizmoworks.com" www.gizmoworks.com> To: aroid-l@www.gizmoworks.com Sent: Wed, 21 July, 2010 18:00:11 Subject: Aroid-L Digest, Vol 72, Issue 22 Send Aroid-L mailing list submissions to aroid-l@www.gizmoworks.com To subscribe or unsubscribe via the World Wide Web, visit http://www.gizmoworks.com/mailman/listinfo/aroid-l or, via email, send a message with subject or body 'help' to aroid-l-request@www.gizmoworks.com You can reach the person managing the list at aroid-l-owner@www.gizmoworks.com When replying, please edit your Subject line so it is more specific than "Re: Contents of Aroid-L digest..."

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 triple 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!
