It's spreading across the entire row of plants. Many plants are losing all their leaves and disappearing.
It starts with the acne, then the leaf seems to almost disintegrate. Online research indicates that Purple Oxalis has no severe pest problems, but can occasionally be damaged by spider mites or leaf miners.
But I've seen no pictures of leaf miner or spider mite damage that looks like this. Is this happening to anyone else?
You haven't sprayed them with anything have you? Looks like a fungus of some kind, the way it starts with a little circle...
ReplyDeleteLooks like rust, a fungus that thrives in the rain and humidity we've had recently. What do the undersides of the leaves look like--do you see any powdery yellow-orange looking stuff?
ReplyDeleteNo answers for you, but I hope you find a solution for such a pretty plant.
ReplyDeleteWe wanted some rain , right! I think it may be the culprit along with heat and humidity. My oxalis often goes away during the summer but will return when it gets cooler. It is really a cool woodland plant.
ReplyDeleteThanks for all the input; I believe Caroline has identified the culprit: rust.
