Mrs. Homegrown here:
While we’re inviting questions, we’ve also got a question for you guys. What sort of critter likes to eat cilantro? I think it’s a critter, not a bug. There’s no sign of leaf damage, just nibbling the stems down. There’s no digging or other disturbance.
Whatever this critter is, it has a defined taste for cilantro, because the cilantro is interplanted with parsley and it never so much as touches the parsley, or anything else in the garden, for that matter. It just comes out at night and decimates the poor cilantro.
