Troubleshooting
Bouquet Dill problems — and how to fix them
Bouquet Dill (Anethum graveolens 'Bouquet') 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.
Lodging (stem toppling)
Tall stems snap or fall over in wind or rain, particularly in rich, wet soil. Stake plants when they reach 45 cm, or site them against a fence or hedge for natural support.
Swallowtail butterfly caterpillars
Black swallowtail larvae feed heavily on dill foliage. Many gardeners plant extra dill to share with these pollinators; otherwise, hand-pick caterpillars if yield is a priority.
Premature seed drop
Ripe seeds scatter quickly once umbels brown. Monitor seed heads closely and harvest when 60–70% of seeds on an umbel have turned brown. Cut heads into a paper bag to capture seeds.
