What's Eating My Parsley?
The most dramatic parsley 'pest' is a future black swallowtail butterfly, and most gardeners end up planting extra parsley on purpose once they meet it. The rest of the list is minor by comparison.
The usual suspects
Parsleyworm (black swallowtail caterpillar)
The signs: Stems stripped of leaves in patches, striking banded caterpillars in plain view.
What it looks like: Plump green caterpillar with black bands and yellow dots; prod it gently and orange horns pop up with a citrus scent.
What to do: Host them if you can — shift them to a spare parsley or dill plant and take the butterflies as payment. Parsley regrows from the crown quickly.
Aphids
The signs: Curled tips, sticky film, slowed growth.
What it looks like: Green clusters on new growth.
What to do: Rinse hard, harvest often, soap if persistent.
Slugs
The signs: Ragged low holes and slime trails in damp weather.
What it looks like: Night feeders under the dense canopy.
What to do: Morning watering and traps; keep mulch a few inches off the crowns.
Rabbits
The signs: Whole plants cropped to stubs, clean angled cuts.
What it looks like: Row-scale loss overnight.
What to do: Low fencing; parsley regrows if the crown survives.
When it's not a pest at all
Second-year parsley bolting to flower is biology, not damage — it's a biennial closing out its run. Yellowing crowded crowns want thinning and feeding, not forensics.
