Amorphophallus titanum leaf cutting

I've had good success with this process (100% for 4 attempts) so I thought I would share so others might give it a try.
On 2-18-13 I took 2- 6 inch cuttings from the mature leaf of the mother plant.

I cut them right at the "Y" and dipped them in Rootone.

I used sterilized potting soil with the fine particles sifted out. The soil is damp, but not soaked, and is left kind of loose and fluffy. My container is a plastic "Critter Keeper" with a heatpad (this was a setup for hermit crabs and the box and heater are available at petstores). The temp is stable around 84f deg. The box is under fluorescent light 12hrs a day.

On 5-23-13 the smaller leaf has this small tuber with no roots yet.

On 6-3-13 the larger leaf has a nice tuber with roots.

On 7-6-13 the smaller leaf/tuber breaks the surface with new growth and gets its own 6"pot.

7-16-13 the sprout from the larger leaf broke the surface and was re-potted. The tuber on this one is larger than a quarter.

This is up to date now, I will add more as it develops.

critter cages huh?? seems like an easy set up.. im all for easy.. :)
i'll have to check them out..
keep us posted on progress..time takes for rooting.. when do u transplant to individual pots???

RE: Amorphophallus titanum leaf cutting

139 days from cut to potting up.

RE: Amorphophallus titanum leaf cutting

very cool mike..
and much thanks for step by step progress with this batch..
so?? do u have a forest of titanums?? :)

RE: Amorphophallus titanum leaf cutting

I updated with the potting up of the second cutting. 149 days from cutting to sprouted tuber.
Lomodor--more like a grove now LOL.

RE: Amorphophallus titanum leaf cutting

For anyone, such as myself that is somewhat unsure where to cut...
I figured out a neat truck to help figure it out

The pic is of a leaf bulb forming inside of A. Symonianus... Any leaf bulb forming type will work, simply back light the leaf and you can very clearly see where the bulb is!
No doubt this would correspond with locating a proper sized node location within a Titan...

It's really cool, even if it had no practical purpose, but I think it's rather useful, it's boosted my confidence on where to make the cut on my Titan!

RE: Amorphophallus titanum leaf cutting

ok gonna try it...:)
my 2nd largest titanum is opening up nicely now..
but..geessshh.. the leaves are HUGE.. they are
7 inches long..
i'll get some good potting mix tomorrow at HD..
did u add any perlite to your mix..or just the mix??
any use of kelp ..anything besides the roottone?
also..once u noticed rooting..did u cut the leaf back any?
did u give any fertilizing up to point of potting up tiny corm?
u r my resource for info..:)
im going to use 10 gallon aquariums.. left over from days when i bred angelfish.. glad i didnt get rid of them..
i guess also not to overwater while they are in rooting container.. no drainage..
did u make holes in bottom of the "critter keeper"?
again..thanks man !!!
grab?? have u tried making cutting yet???

RE: Amorphophallus titanum leaf cutting

My leaf isn't mature yet, I want to let it fully unfurl and fill out first, I may give it another week or 2 beyond that to harden off...

It seems like a recipe for disaster to try it will a leaf that's not ready, they are so succulent and full of water I'm sure it would rot!

RE: Amorphophallus titanum leaf cutting

when your leaves are ready..hope u try it grab..
i set my incubator up this morning..cut 4 leaves..
had to find ones that werent
im using a 10 gal aquarium.. cleaned up..
got some good seedling start mix.. added some perlite
cut the leaves.. dipped them in superthrive.then in the
root hormone powder..
all covered..i have thermostat set on heat mat to 85F
now i wait..:)

RE: Amorphophallus titanum leaf cutting

I guess you already started, but :
Its a sealed system, no drainage, no additional water--the humidity is 100% or so.
The soil is damp, but not wet to start, and I left it very fluffy--not compacted or soggy.
No fert till the tip breaks ground.
Keep us posted!!

RE: Amorphophallus titanum leaf cutting

thanks johnson.. i hope im as successful as u have been..
i added perlite to the was a good quality mix..good and light..
i have plastic over it..and its sealed.. temps are holding
at just under 84F now..
now its the wait.. :)

RE: Amorphophallus titanum leaf cutting


Did the cuttings work?

RE: Amorphophallus titanum leaf cutting

nope..:( sigh..
i used leaves from titanum that has HUGE leaves..
some got almost 14 inches long..
i think when i try it again..i'll use leaves from titanum that has shorter leaves..

RE: Amorphophallus titanum leaf cutting

I believe that you may want to use some plant hormones, rooting hormones, and get them into humidity domes underneath a t5 setup in order to give them the best chance possible.

Also it may help to take the leaf cutting when they appear to have the highest starch content.

I'm nowhere close to the level where i can take cuttings yet.

Couldn't you also air layer them?
