Frequently Asked Questions

What pest or disease commonly affects Anethum graveolens (dill), and how do I control it?

Dill (Anethum graveolens) is especially prone to aphids and, in humid weather, powdery mildew. Spray aphids off with a strong water jet and repeat every 2–3 days for a week, or use insecticidal soap if infestations persist; for powdery mildew, improve airflow by spacing plants and avoid wetting the leaves, then remove heavily affected foliage early.

How can I tell when Mammoth Long Island Dill is ready to harvest?

Harvest dill leaves once plants are about 6–8 inches tall and actively growing, typically around 35–45 days from sowing. For the best flavor, cut leafy sprigs in the morning before heat builds, and harvest flower heads when they start to form and broaden if you’re aiming for seed (they mature after further flowering).
