Anyone know what this is on the basil leaves
I noticed the last week a lot of the different basils are getting these dark spots
If the underside feels "oily" , look for signs of basil downy mildew. Usually the leaves yellow between the veins before the spores become visible. It is unusual to see the leaves look smudged with black first. Sweet basil is the most susceptible.
