Can you direct sow artichokes?

Your artichokes can be grown as short lived perennials and seed should be sown directly into the garden in the fall. When to start seeds is key to healthy flower head production. They will grow into large, bush-like plants that need a very long growing season.

Do artichokes need full sun?

Artichokes thrive in full sun to partial shade. They also need light, fertile, well-drained soil—sandy or loam is ideal. Two reasons artichoke plants fail are summer drought and winter soil that’s waterlogged. Adding compost will improve the soil’s ability to retain water in summer and to drain in winter.

How do you harden an artichoke?

Six weeks before your last frost date, start hardening off seedlings by gradually exposing them to bright sun, wind and cool temperatures. Set artichoke plants out in prepared beds 3 to 4 weeks before your last frost date. Exposure to cool temperatures below 45 degrees is necessary to trigger flowering.

Do artichokes like hot weather?

The plant grows best in cool, mild climates. When it receives careful attention and adequate moisture, however, an artichoke plant grows successfully in hot climates. Artichoke varieties that tolerate hot weather include Green Globe, Emerald, Purple Sicilian, Imperial Star and Madrigal.
