All of a sudden, leaves on a few of my begonias will do this..

Can someone tell me what it could be..I do not put them in full sun..Morning or late afternoon sun is what I provide..I wait until after the mix has dried out before watering again.... I use a well aerated mix that dries out rapidly..

Any help would be appreciated..Thank you so much..

Thank you very much.

What is the composition of your mix for begonias?

Hi rainygarden..

I was told it was a disease and without looking at the link, I can't remember..

It is one that is still in farfard mix which is basically 80% bark, the rust perlite and peat..

I normally grow most my plants in a gritty mix or a mix with very little peat, such as 5 parts bark, one part peat, and one part perlite..

Do have a recommendation? Another idea?

Thank you for asking..:-)

Hi: No, I don't that's why I was asking. The 5-1-1 isn't working for the very small plants I have. I tried to add more peat and that didn't help. I am now spraying
RD-20 fungicide in case it is some kind of fungus. But I think it's too late and now I'll try to root the leaves from the only plant left.

Hi rainygarden,

Mine is not in the 5.1.1 mix...I usually use it, but this time I was lazy and just used the Farfard mix..

I am really starting to think there is some kind of blight going around....Al at the houseplant forums pointed it out to me and I was reading that this disease, affects begonias and grape leaves especially.. Go figure, right?

I have never grown one before, thought I would try, and the only two I have do this...

I am going to do what Al says, and remove all the affeceted leaves and start a couple of cuttings...
I hope it works....:-(
