Q.Snow Pea Disease
My snow pea plants look healthy & are producing lots of peas. Up until the last week or so the peas have been beautiful. Now they have “pitting” on the pods. Inside is still ok. Can you tell me what is wrong? What do I need to do to stop the pitting? Are they still edible?

Further inspection of the plants may be necessary to diagnose the issue.

I would also suggest taking a sample to your County Extension Service.
