I have a question for amorphophallus lovers about watering my titanum. I have brought it in my greenhouse and it stays above 60 in there all winter. Right now it has a huge leaf and i don't want to rot the bulb... How often should i water it ?
Titanum Question?
I'm not sure why no one has responded to your post. Guess everyone is busy. Hopefully someone will come along soon with some advice for you.
I don't know anything about these plants and I see there is no reference to watering in the info given in Plant Files: http://davesgarden.com/guides/pf/go/69521/
Sorry I couldn't help but maybe with me posting it will bump your thread up so someone will see it.
Thanks,
I think everyone is depressed that it is winter...
TT77, I was hoping for some more input too! The pictures of A. titanum looks really cool in PlantFiles. I guess that species is a bit more complicated than the A. konjac
I bought a couple months ago. It had two leaves on it. The smaller one yellowed last month, but the larger one still looks great. I'm worried about killing it with kindness by overwatering, so I'm being really stingy. The high humidity here seems to keep it happy.
I'm keeping my fingers crossed...

I'd love to help, but I can't seem to grow the A. titanum at all, and furthermore, can't find anyone who will tell me how to do it successfully! Incredible but true. I even tried to get info from a vendor at a plant sale; this person had beautifully grown specimens of A. titanum for sale, and I would have bought one from him if he would have told me simply how he did it, but he didn't tell me. So he lost a sale! Other Amorphs I have no problems with, but A. titanum is nearly impossible. I have one that I've had for nearly three years and it is only 4 or 5 inches tall and the tuber stays about the size of a large pea. That's it! Some Titan!
Now, I can grow a titanic Alocasia, though . . .

Hi Guys,
It's just my thought but given the habitat they come from and the kind of controlled greenhouses I've seen them grown in online I'd guess they would want higher temperatures and more humidity than most other aroids whenever they are in growth, but you would need to combine that with a highly organic and perfectly draining soil mix with plenty of available nutrients - remember Borneo is true tropical rainforest territory. I would think that overnight low temperatures at or over 80F and humidity levels over 80 % would be the key. Here in South Australia I can just about do the heat, but our summer humidity is usually 20% or lower. I am experimenting with my first Amorphs ever this year, but I am starting with my sights set a bit lower than A. titanum! TTFN, Kaelkitty.
I recently bought some titanum seeds and, one week after putting them in the propagator, a number are starting to show a small shoot. So, I can't help you with the watering regime, but I hope to have that problem soon!
Truetropical77,
I don't grow your plant but it has come up on a couple sites I monitor. UBC Botanical and aroid-l@www.gizmoworks.com. What they said was don't water when plant is dormant because this will cause rot. I know Steve Lucas at Exotic Rain Forest has correspondence on this and I would suggest you contact Him. Hope this helps. Also, I can send you copies of this information if you want.

Thanks Larry,
I have overwintered many dormant plants, and its relatively easy but my plant isn't dormant. that's why i was confused about how to water. I have a Gigas that sprouted out about the same time as my Titanum and the Gigas is starting to shrivel up, and i'm praying there is a bulb left after it goes dormant! Here is a pic of the Titanum.
Hi, A titanum a does most of its growing in the cooler months of the year. Because of the rapid rate of growth it requires a fairly rich well drained moisture retentive mix. I use 2 parts quality potting mix to 2 parts coarse perlite and one part Spagnum peat. (Not moss.). My plant keeps growing in temps down to 5C (40 F) with no problems. It is quite demanding in it needs, as it will sulk and just sit there if not given the right light, soil , fert, or many other little things . Bob.
Thanks Bob! I will remember this.
