Yesterday my Colocasias were fine, getting big, they looked great. This morning when I went outside, this is what I was greeted with. I have no idea what happened over night!

They weren't dry and have been sitting in the same place since I planted them in late April/early May (I don't remember exactly when.)

I'm sure these leaves are goners, but are the bulbs salvageable? What can I do to save them?

Oh, this makes me very sad :(

Was it very hot?? Mine have had leaves that looked like this is extreme heat and a lack of water.. Some days i water mine 3 times, but its hot here... However as longs the bulbs aren't dried Unless you have spider mites thats the only other thing i can think of that could maybe do this, but if they were fine yesterday i dont think its that.
good luck

They looked great through all the 100+ degree days and last night it cooled down to mid/upper 60's. They were not dry and I see no spider mites. It's the strangest think I've ever seen!

Mary, from a daytime temp of 100 to a nighttime temp of low 60s can be a shock. I keep my calocasias pretty wet all the time. Usually I get new leaves when others die off. Have faith.

They definitely look like they've suddenly lost water, or were cooked in the heat/sun. You've lost a lot of plant energy there but the tubers should come back. I'd check them all the same to make sure there's nothing 'bugging them'.

Thanks everyone. I'll wait till the foliage is completely dead/dry before cutting off and hope they come back. I really don't know what went wrong!

from what i remember leaves that are dead just take energy from the plant... I say cut all but one or two leaves off, leaving the center one, and wait for the new ones to open.. I've cut all my leaves off a few times through the winter, leaving less then an inch sticking out of the dirt (easier to get rid of spider mites that way) and they are always fine... These plants from my experience are pretty hard to kill, unless they freeze (which i've lost a few to) As longs you give them plenty of water they are happy

I notice some plants in the bed right next to them that are showing burn - did anyone (lawn service, etc.) spray anything on them recently? It looks peculiar that right along the bed edge the plants are burnt along with the Colocasias.

LariAnn, the plant behind them are spent and cut sage. Not really burned, just done. But I do think that is what happened to the Colocasias. I think that I burned them with too much food that I was trying to use up...I didn't measure, though I thought I was close (insert eye roll here.)

Well, fingers crossed that they recover. I don't know why, but I just don't have a lot of luck with EEs. I have an A. Amazonica that just week before last, in the crazy storms we had up here, had a much larger plant land on top of it and broke all the leaves off, but one. Sheesh!

dont give up on EE maryev.. :) last yr was my worst yr with EE's.. they didnt get huge like they usually
do..only..or mostly because i was starving the poor things.. LOL
these plants bring an exotic..tropical affect to our gardening..
and many of them are..or can be challenging..which for me makes them even more desirable..
:)
good luck to ya !!!!

I had 6 new plants i ordered last aug?? sept?? cant remember.. anyways they were small plants and i put them in my homemade greenhouse for the winter... The heater died and it was a few days (im guessing) before i noticed and yep all 6 baby plants died plant bulb ect all turned to mush... So again this year i had to add to my collection... Ears ( alocasias and coloasica havent had the chance to try Xanthosomas yet) are in my top 5 fav plants.. sure they can be challenging at times to get them big, multiply ect.. But i for one love them...
i really hope yours makes a recovery

I do love them, too. They are so tropical looking and I wanted something that would get pretty big beside my back door...they do appear to have some new leaf sprouts - I'm hoping they come out healthily.

I cut off all but the middle couple of leaves (one on each plant that has the new leaves coming out of the sides.) I'm optimistic :)

Hi Belle, They came back, but not well. They were sort of pitiful and anemic looking and the tubers rotted in the middle. I ended up throwing them away. I'll try again with new tubers sometime.

I find some rotted corms too but if there are portions of it that are firm I cut it off, wash them well and dry them and most of the time I have good luck with them. In fact I left some Maui magic potted outside the whole winter checked it and was rotted. i did what I just told you and now I see growth. Do not throw anything.

Even coating them with a bit of cinnamon powder after cleaning helps.

I've just started using cinnamon powder on seedlings. I'll keep that in mind next time!
