If you want it to grow more leaves, then give this plant heat. These particular plants love the heat. Regular room temperature just wont do. Mine go outside as soon as it's warm enough to do so. As a matter of fact, it got really chilly last night, so I moved both of mine into my small greenhouse and turned on my little electric heater to keep them warm. I could've just brought them back inside for the night, but my greenhouse stays at around 85-90°F when I keep it heated.

Well, I grow mine outdoors for most of the year, and all throughout the summer, they grow like weeds. They just love this scorching summer heat down here in the South. I keep them where they only get very bright shade, with some early morning/late evening sunlight. All I do for them is just make sure to keep them well watered, and to not let them dry out. It seems like the hotter the weather gets, the more leaves they send out. They have already sent out more leaves than I realized, because when I moved them back to my greenhouse last night, they almost didn't want to fit. And I've noticed that more leaves are beginning to emerge.

I am not an expert but I'm guessing you could cut the stem, I would let it callous a bit, and root that, you might get a good result by burying it horizontally (more room for buds to develop) I think it's also likely that your original plant may sprout new shoots at the base in response to the pruning. Here's a link that might be helpful: http://www.therainforestgarden.com/2011/05/alocasia-propagation-from-cuttings.html

you don't need to cut the trunk - just position it on a diagonal in the pot - some will still stick out , but that's normal. with time they grow trunks. i prefer to grow them in shorter NOT deeper pots, so with time they grow a trunk and you just can't bury it since the pot is not that deep (they might rot in a deeper pot).

i bare-root and repot mine ev 3-4 years - at this point you can usually find many baby-tubers buried in the soil. you can sprout these on a heat mat while keeping them tented and very moist (i do that ). once you dig up the tuber - you'll see that perhaps the deep end declined somewhat and you can just scrape it off, to make it shorter, but do not cut it, if it's firm and live. i mean, i think you can cut it like a potato as smth...but it might rot. i'd callus it for a week and dust with anti fungal or at least cinnamon. If you really want to do that, i'd recommend doing smth funny - put some sort of a plastic cap at the cut, callused and dusted end to prevent contact with soil.

you can even position it horizontally and half-bury it - it would help to put it on a heat mat, as suggested and keeping it very moist at all times. it should sprout multiple eyes.

in general 3-4 leaves on a trunk is all you ever get, unless you are in the tropics - they like it very hot ...and humid..like 90F is very fine indeed :).. if you can't provide that - plant 3-5 tubers in a wide pot and you'll have a nice looking plant ;).

Wow nice!

So beautiful!

@Paul MI

i am curious what you decided to do - to wack or not and how did it go?

Well the jury is still out and will likely be for a while, I imagine. I vacillated back-n-forth on whether to whack or not. Finally, near the beginning of August I couldn't take it anymore and whacked it. (I was quite surprised how easy it was to cut through ... I was expecting a much tougher, more fibrous stem.) I dusted the cuts with cinnamon and allowed them to callous for a couple days. Then wrapped some damp sphagnum around the lower 1/3 of the upper section of the stem, and enclosed that area with a plastic bag. The bagged portion I then laid across one of the shoplights on my lighted plant stand. (Closest I can come to a heat mat.). The lower section is still in the pot. I've had it outside but we've had an unusual number of cooler days for this time of year which -- while very welcomed from a personal comfort point of view -- has no doubt been unbeneficial from the stump's viewpoint.

Hopefully, both sections will make it. But if they both die, then I'll simply stay on the lookout for another cheap one.

In tropic, this kind of plant grow easy, but still, only 3-5 leaves each trunk. Cut the trunk is common since they grow too fast. 1 trunk usually produce 4 buds. In few months, those 4 grow very big again.

this really temps me to wack one of my trunks next year just see how many buds will grow. i'll wait till summer, of course.

Thanks, Gudang. Now I don't feel inadequate for only being able to get it to give me 3-5 leaves at a time. :-)

So update ...much sooner than I had anticipated.

The stump in the pot has yet to do much of anything.

The upper section has had a couple developments. I had left the leaves intact as I did not know if they might provide useful energy to that unrooted portion. Two out of three leaves have died and the third appears to be following suit. I found it surprising that newest developing leaf died first. Rather expected one of the older leaves to have that "honor". The other development was this --

Root development occurred much faster than I had expected. I have potted this section in the same pot as the stump. If things work out well, both will survive and leaf out for a much fuller looking pot.

yah, it's looking good. try to keep it warm for as long as you can, like at least 2 months (mid 70s). 'cause ;)...WINTER is coming!

better yet, put it on a heat mat for a month or two - it needs to make a new leaf before winter, or else it might go dormant without leaves and then it'll take longer to wake up in spring.

good growing!
