Troubleshooting
Parsley problems — and how to fix them
Parsley (Petroselinum crispum) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slow germination
Parsley seed needs 2-4 weeks; pre-soak overnight to speed it up.
Bolting to flower
Heat or under-watering; second-year plants bolt naturally.
Yellow leaves
Hot weather or under-watering.
Carrot fly damage
Same fly as carrots; cover with mesh.
