How to Grow Artichokes
Cynara scolymus
Globe artichokes are statuesque perennials for full sun and deep, fertile, free-draining soil. Start from divisions or seed; plant out after frost. Keep evenly moist, especially during bud formation; mulch annually and divide every ~5 years to maintain vigor. Harvest tight, firm buds before the scales open; leave a few to feed pollinators if desired. Provide space (plants are large) and consider staking in windy sites.

☀️ Light
Full sun in a warm, sheltered spot
Full sun is essential for strong growth and good bud production. Choose a warm, sheltered position away from strong winds which can damage the large leaves.
🌿 Spacing
90-100cm apart; large plants need room
Allow 90-100cm between plants and 120cm between rows. Globe artichokes are large, architectural perennials that need significant space.
💧 Watering
Regular watering during bud formation
Water regularly during hot, dry spells, especially during bud formation when consistent moisture improves bud size and number. Avoid waterlogging in winter.
🌱 Fertilizing
Spring feed; generous compost mulch annually
Feed in spring with a balanced fertiliser. Mulch generously with compost or well-rotted manure. Top-dress with compost annually to maintain fertility.
✂️ Pruning
Cut back in autumn; keep 3-4 strong shoots
Cut back dead stems to ground level in late autumn. In spring, remove small, weak side shoots, keeping the three to four strongest per plant for the best heads.
🍎 Harvesting
Cut tight buds before scales open
Cut heads while still tight, before the scales begin to open. Take the main central head first, then side shoots will produce smaller secondary heads.
🍂 Mulching
Heavy autumn mulch for winter crown protection
Mulch crowns heavily in autumn with straw or dry leaves for winter protection. In cold areas, add a layer of fleece over the mulch.
❄️ Overwintering
Mulch and fleece crowns; replace every 4-5 years
Crowns are vulnerable to cold, wet winters. Mulch heavily with straw or dry leaves in autumn. In exposed or northern gardens, cover with fleece. Replace plants every four to five years with rooted offsets.
Growing Tips
Give them room
Allow 75–90 cm between plants; these are big perennials with deep roots.
Moisture at bud time
Regular watering during hot, dry spells improves bud size and number.
Mulch and feed
Top-dress with compost in spring and renew mulch to suppress weeds and steady moisture.
Renew clumps
Lift and divide mature clumps every few years, keeping the strongest offsets.
Harvest at the sweet spot
Cut buds while tight and heavy; once scales loosen, they become fibrous.
Pests & Diseases
Pest Blackfly (Black Bean Aphid)
Identification: Dense clusters of small black aphids on stems and around developing flower buds; sticky honeydew and sooty mould
- Blast off with a strong jet of water
- Spray with insecticidal soap or neem oil
- Encourage ladybirds, lacewings, and hoverflies
- Spray with a contact insecticide containing pyrethrins
Pest Slugs and Snails
Identification: Irregular holes in young leaves and stems; slime trails visible on and around plants
- Use beer traps or copper tape barriers
- Apply organic slug pellets (ferric phosphate)
- Encourage hedgehogs, frogs, and ground beetles
- Apply slug pellets containing ferric phosphate around plants
Pest Artichoke Plume Moth
Identification: Small caterpillars boring into the base of flower buds; frass visible at entry holes. Adult moths are distinctive with T-shaped wings
- Inspect buds regularly and remove any containing larvae
- Cut and destroy affected buds promptly
- Spray with a contact insecticide containing pyrethrins when adult moths are seen in late spring
Disease Petal Blight Itersonilia perplexans
Symptoms: Brown water-soaked spots on the outer scales of flower heads; spots enlarge and merge in wet weather, causing heads to rot
Treatment: Remove and destroy affected heads promptly. Avoid overhead watering
Prevention: Space plants well for good airflow. Water at the base rather than overhead. Remove affected heads immediately
Disease Crown Rot
Symptoms: Centre of the plant collapses; leaves yellow and wilt from the base. The crown becomes soft and mushy
Treatment: Dig up and destroy affected plants. Improve drainage before replanting in a new position
Prevention: Ensure excellent drainage, especially on heavy clay. Mulch crowns in winter but keep mulch off the crown centre
