Mine did this too, shortly after I got it. I always thought it was some kind of leaf blight.

I know it sounds awful, but I tend to agree with echinaceamaniac: Alocasias aren't, technically, impossible, but they're very, very difficult.

Probably some of what's going on is that your plant is responding to the change in its environment. This is more or less unavoidable, but also, if that's all it does, fairly minor. The bigger problems are these:

-Alocasia are really, really, really prone to spider mites.
-They need crazy high levels of humidity, which you're not likely to be able to provide indoors except maybe in a terrarium.

I won't tell you it's a lost cause, but . . . well, but you know I'm thinking it, right?

There's a good post by water roots about Alocasia here ; check the second part and see if this is something you want to pursue, and if not, the first part has a lot of alternative plants which are much more cooperative.

Thanks everyone. That article was really good:) Although, after reading it, I'm going to give this temperamental plant my best shot and if it dies I probably won't get another one. Let's hope that the plant didn't hear that..... it might drop more leaves...:P

Anyway thanks for all the advice. I will be back:)

What I found odd about mine, though is like... In one instance, the leaves didn't just turn orange -- they had this rotten, fishy smell to them. Also, it was growing in my dorm, which had... fairly high humidty. And all of the other humidty-liking plants I had (Ferns, NIP, Croton -- which did really well, oddly) did pretty fine.

Anyway, new conclusion: Anthuriums have similar foliage and cooler flowers. I'll get one of THOSE the next time I want an aroid (If I ever find one that doesn't have a white spadix with a red spathe. White spadix's make me think peace lily and I don't like those that much and I'm not sure why).

I tried an Alocasia indoors once & it was too difficult for me. I can only grow indoors, so there's only a certain amount of times I'll try something; 3 seems to be my limit -- Alocasia was so difficult for me that I never gave it a 2nd shot.

AMCC,
I'd suggest fishy & rotten smell is really bad news & - rot & if it were mine, I'd toss it (if you haven't already).

Warning here on Anthuriums, as much as I like them (& I currently DO have one which adopted me last year). They can go dormant which is sometimes hard to distinguish from dying. The one in question I bought at a florist (never again, as they specialize in cut flowers not live plants). Since I thought it was dying (suddenly started yellowing), I questioned the florist who had no ideas, I threw it out, later learned it was really dormant. I went back & informed the florist, suggesting it'd be helpful if they knew something abt what they were selling. Since they hadn't I might have simply thrown that $12 directly into the garbage, won't do that again!!

sincve the elephant ears are grown from bulbs they can rot. my experience with any alocasia, is that they do not need a lot of water. and they like the sun

Depends which Alocasia. Some grow in water, some will rot quickly in water. Alocasia 'Poly' is one that will rot quickly in water. My Alocasia macrorrhizos 'Variegata' and Alocasia cucullata are in pots that have been sitting in a pond for years.

Even though this is an older thread, I thought I'd comment on my experience with these plants, since it came back up.

My Alocasia amazonica 'Polly' haven't been finicky for me. Mine have tolerated some neglect last year. Two of the bulbs went dormant through the winter, while the other two kept their leaves. Despite not getting watered as often as they should have. Now that spring is just around the corner, the two dormant bulbs are sending up leaves, while the the two active ones are shedding theirs. They may be going dormant, but I suspect it won't be for very long.

I have since bought yet another one that my local garden center had just gotten in their latest shipment. I was planning on repotting my Alocasias anyways. So I'll be adding the newer plant in along with them into a larger pot. I absolutely love their interesting foliage. I haven't found them to be difficult to grow either. They have been very tolerant of my neglect.

As for Anthuriums, they don't have any form of bulbs, tubers, or rhizomes. So they do not go dormant and continue actively growing throughout the year.

Anyone who can keep these plants alive indoors must have an actual year round greenhouse? They're picky plants even outdoors. Tropicbreezent's way is the only way I've experienced to keep them alive past winter. Kudos to anyone who succeeds. They do add a lot of interest to pond/garden!
