Hi there;

please if any one can help me in identifying a great problem affecting my HUGE Dieffenbachias...it is the incurving of the leaves and falling in clusters..means they fall may be one leaf a week....I feel sooooo worried and need a help....
thank youuuuu

Have you moved it? Repotted it? Over watered it? If its conditions have changed it may drop some leaves due to stress.

Thank you for replying...nothing new....at alllllll
to be honest..it happened before and stopped of it's own..i could not figure out what was there...
what about incurving..?

If it's flowering there can't be that much of a problem. Perhaps giving higher humidity would help?

do you mean that humidity might help incurving....?
e.g: misting..?

It's just a guess, but as I said before, if it is flowering then the plant loves where it is and how it is being treated. I don't think you really have a problem at all.

thank you very much, .....
i have read long back some thing about some deficient minerals / nutrients can affect the plants by incurving.....!
do you know some thing about this..?

Found the following quote on houseplants in general and the other citation about ANTHRACNOSE and Dieffenbachia in particular on this page.

Quote:

"Plant distortion (leaf thickening, curling, leaf and flower drop) accompanied by leaf yellowing and browning may be due to gas fumes or pesticides which are toxic to the plant. Plants are very sensitive to gases and will show symptoms before the gas concentration is at a level detectable to humans. Garden soil that is contaminated with agricultural chemicals and used for potting house plants can result in chemical injury to the house plants."

Also, towards the bottom of the same page it describes symptoms of infection by the Anthracnose fungus. Harry

chek for spider mites also .. give the plant a good misting and looks for webs .. also they are touchy to water .. try leaveing your water out over night .

Thank you Marn for advicing......
my plants are great and I don't think there are such infection...though, I will look for it...
I am watering them nearly regular and even using some nutrients which give them a marvelous results....
only the curling of the leaves and the occasional yellowing and falling....are my MAIN problems...
have a great day.
