Artichokes are unique plants that are cultivated for their edible flower buds They are members of the thistle family and grow best in warm, Mediterranean climates The plants are large, reaching up to 6 feet tall and 4 feet wide when mature.

Artichokes produce tasty globes and beautiful purple flowers. They make a stunning ornamental addition to any garden but also supply a nutritious food source. These hardy plants are not difficult to grow, but you may encounter some pest problems from time to time.

Common Artichoke Pests to Watch For

Artichokes can fall victim to various insects fungi and other organisms. Here are some of the most common artichoke pests to be on the lookout for

Insects

• Aphids – These small, pear-shaped sap-sucking insects can weaken and even kill plants. Watch for curled leaves, stunted growth, and yellowing.

• Thrips – Tiny winged pests that feed on sap and can transmit disease. Look for damaged leaves and flowers.

• Mites – Microscopic spiders that suck juices from leaves, causing stippling, discoloration, and wilting.

• Whiteflies – Flying insects that excrete sticky honeydew and promote sooty mold growth.

• Leafminers – Larvae of small flies that tunnel between leaf surfaces and create meandering trails.

• Caterpillars – Voracious eating machines that can quickly defoliate plants. Watch for armyworms, loopers, and cutworms.

• Weevils – Beetles with long snouts that bore into stems and buds. Damage leads to wilting.

• Leafhoppers – Jumping bugs that feed on sap and transmit disease. Look for yellowing and curling.

Other Pests

• Snails and Slugs – Nocturnal mollusks that chew holes in leaves and stems. Look for slime trails.

• Rodents – Mice, rats, squirrels, and other critters that nibble on leaves, stems, and roots. Monitor for damage near base of plants.

• Deer – Hungry ungulates that feed on buds, leaves, and stems. Use fencing to protect plants.

• Birds – Greedy beasts that peck at buds and foliage. Scarecrows and netting can help deter them.

Diseases

• Verticillium Wilt – Fungal disease that clogs water conducting vessels, leading to wilting and dieback.

• Root Rot – Fungi that infect roots and cause deterioration, stunted growth, and death.

• Powdery Mildew – White fungal coating that covers leaves, causing dieback.

• Botrytis Blight – Also called gray mold, this fungus causes buds to rot and collapse.

Preventing Artichoke Pest Problems

An ounce of prevention is worth a pound of cure when it comes to managing artichoke pests. Here are some tips to avoid problems:

• Select pest and disease resistant artichoke varieties when possible.

• Rotate crops each year to prevent pathogen buildup in soil. Avoid planting in same spot as strawberries or lettuces.

• Remove weeds, debris, and plant litter that can harbor overwintering pests.

• Apply organic mulch like wood chips around bases of plants to deter weeds and slugs.

• Use row covers over plants when they are young and most vulnerable.

• Monitor plants frequently and remove diseased material immediately.

• Promote air circulation and avoid overhead watering to reduce fungal disease.

• Fertilize appropriately to encourage vigor and discourage pests.

• Consider companion planting with pest repelling plants like onions, garlic, and flowers.

Control Methods for Existing Infestations

If preventive measures have failed and pests or diseases take hold, don’t panic! Here are some organic and low-toxicity treatment options:

• Insects – Apply insecticidal soap, neem oil, or spinosad to control populations. Target undersides of leaves.

• Large larvae – Hand pick and drop into soapy water to quickly dispatch.

• Fungal diseases – Prune out affected parts immediately. Apply copper fungicide sprays.

• Bacterial diseases – These cannot be treated. Remove whole infected plants.

• Rodents – Use humane traps and reduce hiding spots by clearing debris.

• Deer/birds – Scare with loud sounds, fake predators, or string up glittery old CDs to frighten them off.

• Slugs/snails – Capture underneath boards or in beer traps. Spread diatomaceous earth.

Focus Efforts on Prevention

While dealing with artichoke pests can be challenging, the best approach is to focus most of your efforts on prevention. Start with selecting resistant varieties, maintaining vigilant garden sanitation, rotating crops annually, and promoting optimal growing conditions. Monitor plants closely and address any signs of trouble immediately before infestations get out of hand. With diligent prevention and prompt treatment of problems, you can enjoy a bountiful artichoke harvest each season.
