Troubleshooting
Dill problems — and how to fix them
Dill (Anethum graveolens) 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.
Bolting fast
Heat triggers flowering; succession-sow every 3 weeks.
Falls over
Top-heavy stems; stake or grow against a fence.
Swallowtail caterpillars
Beneficial; plant extra for them.
Aphids on shoot tips
Rinse off or use horticultural soap.
Poor germination
Old seed; use fresh and surface-sow (needs light).
