I think mine have the magnesium deficiency, thanks for the tip. i have been using an organic fertilizer that has a little bit of magnesium in it, but it must not be quite enough. My titan arums aren't looking too good, though they are still alive and growing (kinda).

There is a very good possibility that they may be going into dormancy. If you feel down into the soil, and there's an expanding corm down there, then it means they may be coming close to taking a break from growing which can last for 2-3 months.

I've already seen this happen on around 10 of mine. Their leaves turn yellow, then brown, wilt away, and all you are left with is the corm while the roots rot away too. After keeping them sparingly watered, and allowing them to have a break for a couple months, they will start putting out a new petiole, likely larger than the one that finished growing.


I have one that is over 2 feet tall growing its 3rd petiole however that petiole happens to wilt more and more as the 3rd petiole keeps getting bigger. Some go dormant while others just keep growing.

The a konjac produced a flower again this year pretty much the same exact size as the one from last year, but that has since wilted, and the petiole should be up in another year. I wa hoping for it to charge up more energy and produce an even larger bloom, but I guess it will keep splitting and max out at a size of a small pineapple.

I have only kept 1 of the a titanums and that one has since gone dormant 3 weeks ago leaving a corm nearly 2 inches in diameter, bigger than a golf ball, and pretty heavy. Based on its appearance, it shoul activate in 4-8 weeks.

Here are a couple of pictures. I'll try to get more seeds from aliexpress because these things are pretty cool.
