Tan Edges Around Parsley Leaves #877438
Asked July 16, 2024, 10:18 AM EDT
One parsley plant (far removed from other parsley plants by about 100 feet) keeps developing tan around leaf edges. New leaves come in unaffected and as they age they develop tan edging. What could be causing this and is it edible? Should I pull the entire plant and dispose? Thanks, in advance.

Expert Response
I think your parsley is suffering from lack of water and the heat.
A survival mechanism used by some plant types is that the outer margins of a leaf will dry up, but the leaf as a whole remains viable. This may be more common in large-leaved plants like squash and pumpkin, where there is more leaf surface area to “spare” and still maintain function. Dry leaf edges can appear similar to disease symptoms.
