Please rescue my sage! Leaves curl! (Pics)
It started last week after rain: Some leaves of my sage (the ordinary, culinary kind) looked a bit crumpled.
Today lots of leaves are dark brown at the edges and/or tips. The more affected leaves have curled upwards. Their tips are completely dry and break when touched.
Some days before the first symptoms occured, I sprayed the plant with a concoction of neem oil and baking soda for powdery mildew. This treatment has not hurt it (or any other of my salvia) before - but maybe the leaves could have got sunburnt this time?
Or could it be a fungus?
I would appreciate any help! I have grown this little plant from seed, and I really like it...
