I have oriental lilies growing in a pot. I am seeing some powdery stuff on many of its leaves.
Does anyone know what that is and if it bad for Lily plant? Also, how can I get rid of it?
I see some light colored 'debris' (insect bodies?) and what looks like spots of damaged tissue as if an insect has rasped some areas of 2 or 3 leaves.
Overall the foliage looks healthy. I'd rinse the leaves with the hose and check for new debris the following days. Check the undersides of the leaves too.
