fun observation i had on my smaller titanum the other day..
i was watering/fertilizing.. and i saw this protusion out of one of the
drainage holes of pot..what was it??? a root.. this is like 7" (18cm) below
the top of corm.. thats one longgggggg root..:)
im anxious when it goes dormant and i unpot it..to see how much growth the
corm put on this growing season.
the large corm petiole hasnt broke top of potting mix..yet.. i buried it with
8" ( 20 cm) of potting mix over the corm.. i think with a corm this size it will
need plenty of room for roots to develop..
growing season for me is just starting..so anxious to see how big these
"kids" get.. LOL

wonder if were gonna have a monster hot summer this yr???
i see the NOAA is forcasting well above temps for center of USA..
utah on edge of it..but above temps is the "prediction forcast"..

The titanum I repotted still hasn't surfaced. I sent down an exploratory team to investigate. It appears the tuber is sprouting but still very short. Couldn't risk going under the tuber to check that other growth.

It's been windy again the past couple of days. The titanums aren't liking it. The shade cloth isn't heavy enough and the Poinciana tree it's under is losing its leaves fast. With the hot dry wind and the sun coming through too strong the leaflets are wilting each day but still hanging in. I'm going to have to start looking for another solution.

tropic..im sure u will come up with good solution to your wind and
protection for your titanums..:)
i hear ya on being anxious to know whats going on under the potting mix..
lol.. until we see the petiole show its head..always wondering..??? is it rotting,
still dormant.. growing..??
no strong winds much here..my situation is strong hot direct sun..
luckily neighbours have a big pine tree that gives afternoon shade to small part of
my yard..so thats where my amorphs are going to be spending the summer...
actually thinking of getting something that is strong..and could elevate the pots even
just an inch (couple cm) above the ground..for pots to have even better drainage..
not sure i really do need it..with new potting mix im using..
just always thinkin of "wonder if..." :)

hope u all are doing good out there.. guess in southern hemisphere going into..
autumn.. here full on summer.. yea!!! for me..LOL :)
?? question..a good/new friend and new to titanum..is having slow response
to his titanum corm comming out of dormancy..
he got it from ..what i think..is best source of titanums here..(tindara)
i told him..my very "new" expreriences with titanums as with ive found with
all amorphs.and especially the "tropicals" is they will come out of dormancy
when they are good and ready.. :)
my 3 largest.. 17#,12#,and 6# are just popping there petiole heads out of
top of potting mix..
my friend is in mid south..and is keeping his corm in a greenhouse.. nites
are 70F ( 21 C) which seems good to me..
so..anyone else experiencing there titanums..or any of there amorphs
slow to growth???
much thanks...

With 21C in a greenhouse the titanums should be okay to come up. But remember, they're equatorial, no summer/winter varaition as such. Technically 2 wet seasons, although you could say it rains right through. So their cycle isn't geared up to your summers and winters. They're probably going to respond to the time interval since last growing. Tindara would have them in an artificially heated environment. Their plants are probably on all different cycles. Can't explain why my little ones keep going right through, one of them having grown constantly for about 3 years now with up to 3 petioles at the one time. It definitely seems keen to grow bigger.

good info tropic!!! as always.. :)
im finding that is so true with corms i get from tindara..
ive bought some late spring (my spring) may.. and ive gotten
one in late summer (my summer) august..
as u said.. because they are greenhouse grown..the corms have
developed there own cycles of growth and dormancy..
my small titanum in earlier pic.. has been in almost constant growth..
i think it had a dormancy of maybe a month..if that..and pop..out came
another petiole..
i think ..me having to adapt to what the particular titanums culture is.. dormancy/
vegy growth/hopefully one day FLOWERING !!! :) is what makes it facinating
for me..
its challenging..in many ways.. especially when they get huge.. but also..
when ya see a healthy,agressive vegy growth.. i can know.. i had a hand in
that.. :)
still hoping to get a descus-salvae, and gigas.. making some good friends
over on IAS.. so..hopefully !!!
tropic??? u have any gators make all those ponds u put in... there home???
if so.. be careful man...

By the way, winter starts here 1st of June. Autumn starts 1st of March, spring 1st of September and summer 1st of December.

So far my larger ponds/waterholes dry up in the dry season. Crocs know that's not a time to stay around. But when I start making them permanent they will be fenced in.

well the small titanum leaf shriveled..and unpotting it..theres it is..another
sprout already comming up..
?? tropic..you said you had a smaller titanum that was the"little engine that could" too??
stayed in vegetative growth for along time..without much or any dormancy between
old/new petiole??
looks like thats what this one is doing.. good by me..hope the corm puts on some
nice size again !
heres couple pics of my everrrrrrr so..slooooowwwww growing titanums..
lol.. in the last 8 days or so..they have come more to life..
odd..the taller one..is 2nd one planted..almost a month later..?? go figure..
short one..is the 17# ( 7.7 kg), the taller petiole started at 12 # ( 5.4 kg) as of today..its 21" ( 53 cm ) tall..
both corms have really extensive root growth and developement..so i guess everything is good..
i'll be overwintering them in the house for sure.. i'll have to haul them in early sept..
nites will be to cool for them..
the fully leafed out amorh is a big konjac..

We're on the other side of mid winter, and come August it should stay consistently warmer. The last couple of mornings we had what I call our freezes, got down to 11.5C. Going up now so hope that's it for the year.

The titanum that's never gone dormant (always had one or two new leaves fully open before the oldest withered) is still going with only one leaf now. It was sitting in the biggest titanum's pot and because I couldn't repot (because it's constantly growing) I cut part of the pot away and filled over with new soil. When the old large titanum finally withered I took out the tuber and filled in with new soil. So now the young one has the whole pot to itself.

The seedling that did go dormant is getting ready to unfurl its leaflets. It's much smaller than the seedling that has never gone dormant. But it has new soil so should go well.

The old larger tuber is sitting in a box. Got a new pot and set it up with soil and now letting the soil settle in. Tomorrow I hope to put fungicide through it, and a few days later replant the large tuber. It's not showing any sign of emerging, apart from a small stub at the top of the tuber. But it's better off in the pot. It's always been an end of November/early December starter.

They're all in the new location, shade from tree canopy, up against a tough species of bamboo, and sheltered from wind by lots of trees and other plants.

???
has anyone else noticed that some college/unis greenhouses have
flowering titanums in what i think of as... "not so big pots:"???
another one is blooming in WI ..and is getting the publicity..which i think
is very cool!!!...
but looking at the pot they have it in..it looks like around 24" wide pot..
and to me..for a flowering titanum corm.. around 6 yrs old..and probably
around 50 lbs.. so..im guessing..thats probably around 16 " wide corm..
so.. seems to me ..if it is how im perceiving the pot..as a 24" pot.. thats not
alot of room for the corm... am i nuts????
my understanding with titanums.. they like lots of room..for their root system
to spread out..????
what do u all think?????

heres pic of most leafed out large titanum..
it was 12 pounds ( 5.4 kg) when i potted it up..
its 50 inches tall so far ( 127 cm) im thinking from past experience
that it could put on another 6-10 inches before its done..then the leaves
will spread out..and drop a bit in height..
its 5.5 inches ( 14 cm) in girth at the base of the petiole..
the larger..and definately more stuborn titanum..is comming along..
just at its own sweet time..LOL... :)

I guess in Poland he'd have his work cut out getting titanums flowering and seeding. Unless he has suppliers in Sumatra (or selewhere in Indonesia) sending them to him. Tindara in the US used to sell them. Have they stopped?

dont know the details of why tindara isnt selling amorphs anymore..and the brother
in law is..
it was lou that has the greenhouses and started with the amorphs in the 1st place..as i understand
it.. and he is the one selling on ebay this summer..
i got a couple more from him.. like i really need more titanums.. LOL :)
there is a guy in germany that sells small corms.. titanums,hewittii,gigas,and descus-salvae..as i
understand.. i think he does leaf cuttings..but i could be wrong on that part..
ive gotten to know him some from aroid.org.. really good guy..
he wont have anything for sale until fall.. he deals only in small corms..no big plants.. i dont think he
has the room..

once they get going..
the 12# titanum is now 68 inches (173 cm) tall and the petiole is
just over 6 inches (15 cm) wide at the base..
not sure it will put on much more height..before the leaves open up..and it drops
a bit in height..
heres a couple pics..
the bigger corm .. 17 pounds.. "mr slow" is slowwwwwlllly comming alive.. its now
28 inches (71 cm) tall.. sigh.. snorrrrrr.. LOL

That's not a "mushroom" that grows from the A. paeoniifolius tuber. It's the usual aroid spathe and spadix, just that the spadix is a bit different shaped to most other aroids.

HI Dave,
The titanum is doing great, and the automatic watering system worked like a charm while we were gone for 9 days. It's 11 ft tall (from the bottom of the pot), bumping up against the ceiling of the garage, with parts of the leaf (petiole?) hanging over the rails for the garage door (see the pic with my daughter standing next to it). I still have the plant light sitting on the edge of the pot facing up since there is no room above the plant, and it seems to be working.
I'm starting to think about dormancy and next year. Has anyone trying cutting back on the watering to induce dormancy? It would be much easier if it was dormant over our coldest months, as I'm thinking I could heat the garage so it was a minimum of 65-70 degrees, rather than 80-85. With respect to repotting, Tindara said the bulb could double or triple in size in a year (I should be so lucky, growing it in a garage!), and they also recommended 6-8" between the bulb and the side of the pot. That's going to be one big pot!

hey steve !!! great to hear from you..
and way to go on that vegetative growth !!!
you said your corm was around 20# when u potted it up??
from my very limited experience with titanums..tropic in darwin australia knows more..
but from my experience..only going on 3rd yr now.. is these plants will do what they want
when they want.. sigh..:)
i had same thinking as you.."ok.now what can i do to induce dormancy in dec-march.."
i dont think its possible..sigh..:(
i know lou where u bought the corm from..he is very helpful and open to culture talk..
and the guy has grown 1000s of titanums..
also over on IAS (international aroid society) there are some good people there.. takes time
to get there attention..but especially in germany..there are some pretty serious amorph growers..
what im planning to do.. is when my largest titanums are there..probably 2 growing seasons out
so somewhere in 2015.. im going to have to put up a tall greenhouse.
one reason im sure not so many gardeneres ..in non tropical areas.. dont get to deep into
the "tropical" amorphs.. titanum,gigas,hewiittii, descus-salvae.. is the mature size of the
vegetative growth.. titanum can be as tall as 18 ft ..i bet lou has some taller..
just a thought steve.. where your at..not real cold in winter.. maybe you could put up a semi perminant greenhouse when your monster is in leaf..
move it only when dormant..
and potting.. with size youre at now.. you are going to need a bigger pot.. ive done my google searching.. what im going to go into are huge fabric pots.. there are BIG pots out there..and they
are PRICEY !!!
and ya..if you grow it well.. if you did start with a 20# corrm.. you could easily have a 50 # one
at end of this growth season.. when its done..
keep us posted steve...
?? is that your daughter??? what does she think of dads monster plant???? :)

well "mr slow" titanum is finally gettin the go on !!
snore.. :) im learning..these plants come out of dormancy when they
want.. and they put on the growth ..when they are good and ready..
of course..they need our loving care to give them what they need to
do well...
as of today.."mr slow" is 47 inches (119 cm) tall. above the pot..
it will probably put on another 6+ inches of height before the leaves
unfurl..and spread out..and drop some..
the outdoor "tropical" amorphs probably have maybe another
3 weeks of outdoor living..before nite temps get into low 60sF
and i dont think they will like that..
??? u all think so too????

It's been pretty fascinating reading all of your posts. Sort of on a whim I purchased a 4# A. titanum on Ebay recently, as well as several A. konjac. I'm still waiting for them to arrive. Once I'd actually paid for them I realized that I knew next to nothing about growing them. LOL.

I'm wondering if an orchid mix would be suitable for the amorphophalli as they appear to require good drainage. Also curious if soil sterilization is as important as I have read on certain sites.

As I'm here in southern Florida, I'm wondering if it is "safe" to plant them in the ground or if I'd be better advised to pot them. My gut is telling me that the konjacs may be fine in the ground, but that I should perhaps raise the titanum in a pot.

Any advice you guys can give this budding plant nut would be appreciated. I have a large yard and have been going pretty hog wild collecting plants that I acquire at the Fairchild Botanical Garden and elsewhere. A pricey habit, but a fascinating (and often rewarding) one.

Thanks for reading.

gjames..
these facinating amorphs are facinating plants.. :)
this is just my 3rd season..so i consider myself a "newbie" ..:)
you are fortunate to live so south ..and southern florida too..
i would think konjac would be fine planting in ground where you're at..
im thinking the soil where u r at is pretty compact clay/coral..??
if so..u will need to dig in some ammendment to make sure for good drainage
around the corm ..so they dont sit in to much water..
titanum. even those living in "tropical" areas.. darwin australia.. tropic is there..
plant there titanums in pots..
even though where youre at.."subtropical".. you do have some chilly weather..off and on..
i know lari ann gardiner..in miami area..she puts here tender alocasias under a "greenhouse'
for extra protection from those rare..but happening chilly nites/early mornings..
seems many people use various potting mix for titanum..
winniorchids/tindara.. they use commercial mix..and they are very successful growing titanums
i am sold ..for my purposes.. using 80% pine bark.. 20% pumice.. with added nutrients..
all my amorphs are doing great in that mix.. i do water more often..but no issues with drainage..
and the plants are getting the needed nutrients for vegetative growth..
hope you take pics..and post them...theres so much to learn from each other..
good luck !!!!!

tropicalnut, thanks for your response. I received my A. konjacs today. Will likely find a spot for them in the garden tomorrow. Once the A. titanium arrives I'll decide what size pot it should have. I really am looking forward to this (with fingers crossed).

summer is starting to wind down here..
sigh..means all those "tropical" amorphs get to come inside..
oh boy.LOL
"mr slow" titanum has now surpassed the faster growing one now..
"mr slow" is 87 inches (220 cm) tall ..above the pot..
the petiole girth isnt as big in diameter as other larger titanum..but i noticed
a fair amount of the girth growth with other titanum came after the plant achieved
its full height..??? dont know if thats significant..
we had a MONSTER storm here last sat.. 2 tornadoes, very high winds..some
hurricane like rain.. not typical utah weather..any time of yr..
wind actually blew over the 2nd largest titanum.. i bet that babi weighs over 200#
plant is fine.. sigh..:)
made me think of your weather tropic..u get down under..when you get those monster
tropical storms.. only on a much smaller scale..of course..
still have ceiling room for the titanums..this yr.. LOL
of course the 87 in tall one..will loose some of that height in next couple weeks..when
leaves fill out and spread..
i did take a small peak at the roots of titanum that blew over.. a TON of roots..everywhere
YEA !!! that has to be a good sign..
im liking this new potting mix im using ..more and more..
also..i think using a biological fungicide , humic/fulvic acid,and kelp powder
have helped too..
thanks to tropic for putting me on to using a fungicide.. hopefully that will prevent any
rot in the corms...
i'll get a pic of "mr slow" next couple days..

were solid in winter here now..sigh.. :( but my titanums are doing good..
one ..i would call a small/medium corm..5 # has put up a monster petiole..
??? its the tallest so far..the unfurled leaves hit the ceiling and now are just
starting to unfurl.. if it had the ceiling height room..it would have been over
9ft tall..it'll be over 8ft when it finishes out spreading out..???its only a 5 # corm???
hey to all of u...??? how long do u find the duration of vegetative growth?? not for
small corms..but 7+# corms??? i have one the 12# corm that is going on 8 months..
the leaves got beat up from a late summer storm..we had powerful winds..actually
topped the pot over ..didnt seem to hurt any growth though..leaves did get a
bit shredded..but..its going good.. was thinking it might start dormancy early spring
2014..putting it just under a yr growth.. ??? thoughts???
i know these plants beat to there own drummer.. which i find interesting..im the
one that has to adjust..:) LOL
ive been giving the full stage vegy growth plants a good dose of P every other
fertilizing..otherwise i give 20:20:20 fertilizer..along with fungicide,kelp,amino acids.
hope alls well with u alls plants...

wow..its been over a month and no one posting on our obsession..titanums..
lol ;)
how are all u all's titanums doing???
i have 1 larger one..i think its the 12# starting its dormancy.. petiole is starting
to shrink..leaves are ok..but some drying up..
other large ones going strong..
1 of the small corms..2" diameter.. is comming out of dormancy..i checked before
christmas.. has a nice white shoot potting up.. YEA !!
small hewetti around 2" diameter..is still dormant.. larger hewettii corm in growth now..
(was around 5 " diameter) is starting to look like waining..hopefully just starting dormancy.. its
been in vegetative growth since may 2013..
i backed off watering some since all plants are in house now.. potting mix is on slightly drier
side..hopefully hasnt adversely harmed corm/roots.. plants look great..so..???
best wishes into new year to all !!!!!

wow..new year..and i cant believe jan is almost over.. glad though !!!!!!!!!!
bring on the warmer weather!!!!!! :)
well the one titanum petiole remains finally sluffed off.. so i got to open my
christmas present !! :)
just a kid arent i..:)
heres a couple pics..
i cant remember what size this corm was originally.. i thought it was the
17# one..but its not.. im thinking it was around 7#..but i have 9 titanums now.and
i didnt mark anything down.. im a BAD scientist!!!
one thing i was amazed by are the massive roots on the corm..
?? is this typical of a corm going out of growth into dormancy??
i dusted the corm with cinnamon (just in case of any fungal growths..)
i'll pot it up again this weekend.. im keeping it semi moist in moisted peat moss.
i am going to put it in a larger pot.. i was going to put in in a 80 gal pot i ordered..but
i think im overkilling..and would kill my back..LOL so its going in a 45 gal pot..
its 31" wide..so hopefully good room for root growth..and "hopefully" corm growth!!!
this corm looks bigger than it really is..the roots are so massive.. the corm
is just under 9 inches wide..

i bet u know the answer to that belle...:)
we all find our ways to get gardening..even if the weather isnt cooperating..
lol weve had a couple rainy/wet snow days .. welcome the moisture for sure..
its been a pretty dry winter here..we had snow in nov..then nothin..
i also have a hewettii to unpot soon..the petiole has slumped over now..
hope it put on some size!!! :)
it just like christmas..get to see how the plant did..or how well i grew it..

potted up the hewettii, will get the titanum potted today or tomorrow..
interestingly.. my largest titanum corm (last yr) and potted up 1st..somewhere
early may..is going strong..and showing no sign of wanting to go into dormancy..
whew..i didnt kill it..sigh..
im anxious to see how big the corm is..i do think i wont get the kind of corm growth
results that those of you that grow titanum in greenhouse..or tropical climates..
i do hope that i can keep these wonderful plants going..and MAYBE!!! get some to
bloom one day !!!!!!!!!!!!!! :)
i know theres been discussion on what size titanum corms need to be to flower..
ive read (real examples..not just talk) of titanums flowering as small as 30#..and then
needing to be much larger... again.it will be interesting to see how big my largest corms
got this last grow season..
??? how are all others titanums doing?????

titanum in last pic..is now sending up a petiole..
seems fast to me..???
largest titanums.. 1 is slowwwwwlllllyyyyy going dormant..LOL
i think i should be glad.. :) i am anxious to see the corm..
other large titanum.. going like crazy.. no leaf drying or any signs of
wanting to rest..
3 of the other titanums..that went dormant late last fall (odd seems to me??)
and just sitting there.. corms are nice and firm.. small white petiole showing..
but no significant growth of petiole for months..
these plants truely do grow to the beat of there own drummer..
surely makes them interesting.. :)
??? hows everyone elses doing??????

My largest is still dormant, about 6 months so far, usually starts again about September. One of the smaller ones went dormant a couple of months back, first time since it was a seed. It had been going constantly with sometimes 2 or 3 petioles at the same time. The other small one is still going, probably not too long before it goes into extended dormancy. Seems as they get older they need more sleep (long "nanny naps"?).

The older leaf cutting finally withered without producing any sort of tuber, the younger leaf cutting is still going but slightly yellowed. Seeing it's been going about 3 months I'm more confident it'll eventually produce a tuber. Here's hoping anyway.
