Frequently Asked Questions


What pest or disease most commonly affects Cynara scolymus (artichoke) and how can I control it?
Artichokes commonly suffer from downy mildew (often seen as yellow patches on leaf tops with a gray-purple growth underneath) and botrytis/stem rots in humid conditions. Improve air flow by spacing plants and removing heavily infected leaves, then water at the base to keep foliage dry. If mildew appears, apply a labeled fungicide for artichokes and repeat as directed, especially during cool, damp weather.
How often should I water Cynara scolymus during active growth, and what soil moisture level should I aim for?
During the main growth phase (from leaf-out until bud set), keep soil evenly moist but not soggy—aim for the top 1–2 inches to dry slightly before watering again. In typical summer conditions this often works out to about 1–2 inches of water per week total (more in heat, less in cool cloudy spells). Use deep watering to reach the root zone because consistently wet soil around crowns can invite rot.
How do I tell when Cynara scolymus is ready to harvest?
Harvest when the buds are fully sized and the bracts are still tight—usually when the central choke is just beginning to loosen but before the buds open and show purple flowers. For best eating, cut buds early in the morning and harvest as soon as buds reach maturity (around 120 days). If you wait for bracts to spread and flowers to appear, the artichoke becomes tough and less flavorful.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 45°F before moving outdoors. Harden off for 7 days first.

Expert Note

Start early and transplant only when nights are reliably mild, then keep crowns evenly moist for the biggest bud size.
