How to Grow Artichokes (Globe) in Tropical Australia

When to Plant

Globe artichokes are poorly suited to the tropics. The plant requires a period of winter chill (vernalisation) to initiate flower buds. Tropical heat and humidity cause crown rot and poor bud formation. Honest assessment: do not waste your time.

Soil
Well-drained, deep, fertile sandy loam enriched with compost and aged manure
pH Range
6.5-7.5
Sunlight
Full sun (minimum 6 hours direct)
Spacing
100cm apart, 150cm between rows
Watering
Deep watering twice weekly during bud development. Reduce in winter dormancy. Consistent moisture is critical during bud formation or buds will be small and tough.

Companion plants: Sunflower, Tarragon, Peas, Cabbage family

Avoid planting near: Other Asteraceae competing for nutrients

Tropical Growing Tips for Artichokes (Globe)

Recommended Varieties

  • Not recommended for tropical zones

Key Challenges

  • Insufficient winter chill for bud initiation
  • Crown rot from wet season humidity
  • Poor bud quality in heat

Pro Tips

  • If you must try, grow as an ornamental only
  • Raised beds with very free-draining mix are essential
  • Try the cardoon (Cynara cardunculus) instead. It is the same species but grown for stems, not buds, and tolerates heat better

Harvesting Artichokes (Globe)

When ready: Buds should be tight, compact, and heavy for their size. Bracts (scales) should still be tightly closed. The main central bud is harvested first at about 8-10cm diameter, which promotes development of smaller side buds.

How to harvest: Cut stem 5-8cm below the bud with sharp secateurs. Harvest in the morning. Once bracts start to open or turn purple at tips, the bud is past prime and will be tough and fibrous.

Where to next

Also worth sowing in the tropical zone this September: Lemongrass, Ginger, Cucumber and Basil.
