Thyme Tempest: A Tale of Woe?

As summer’s fiery breath parches the earth, thyme plants, with their thirst unquenched, become increasingly vulnerable to leaf spot diseases. This insidious assault is often initiated by airborne fungal spores that, upon landing on the leaves, germinate and penetrate the leaf tissue, giving rise to telltale signs of infection.

Initially, small, circular spots may appear on the leaves, ranging in color from pale yellow to dark brown. As the infection progresses, these spots expand, eventually coalescing to form larger, irregular blotches that can engulf the entire leaf. In severe cases, the leaves may turn brown and wither, prematurely falling from the plant.
