Frequently Asked Questions

What pest or disease most commonly affects globe artichokes (Cynara scolymus), and how can I manage it?

In home gardens, globe artichokes commonly suffer from artichoke plume moth/caterpillars and Botrytis (gray mold) during cool, damp weather. Inspect plants weekly for webbing or bored buds/leaves, then remove affected buds and use an appropriate BT (Bacillus thuringiensis) spray on caterpillar stages. For Botrytis, keep the crown and bud area drier by spacing plants for airflow and watering at the soil line, then remove any gray, soft tissue immediately to prevent spread.

How often should I water Cynara scolymus during the main growing phase?

During active growth (after establishment through bud formation), keep the root zone evenly moist but never waterlogged—aim for about 1–2 inches (2.5–5 cm) of water per week depending on heat and soil. Water deeply when the top 1 inch (2.5 cm) of soil feels dry, and avoid frequent light sprinkling that keeps crowns and outer leaves wet. Mulch helps stabilize moisture, which is critical because globe artichokes are sensitive to drying out right before and during bud development.

How do I tell when Cynara scolymus 'Green Globe' is ready to harvest?

Harvest when the buds reach full size and the bracts are still tightly closed, typically about 60–90 days after first bud emergence. Look for buds that feel firm and heavy in the hand, with a bright green color and minimal separation at the tips—if the bracts start to loosen and open, quality declines. Cut the bud with 2–3 inches (5–7 cm) of stem before the flower opens for best eating.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 40°F before moving outdoors. Harden off for 7 days first.

Expert Note

For strongest head production, grow artichokes as a long-season perennial in a well-amended, well-drained bed and protect crowns in winter.
