Growing artichokes is a rewarding experience, but they can be a bit demanding. Choosing the right artichoke companion plants is a simple way to support their growth and boost your whole garden’s health.
Companion planting is about placing plants together for mutual benefit. It can improve soil, attract helpful insects, and deter pests naturally. For your artichokes, this means stronger plants and better harvests.
Artichoke Companion Plants
This list focuses on plants that truly help artichokes thrive. We’ll look at why each partnership works so well.
Best Flower Companions
Flowers aren’t just pretty. They bring in pollinators and predatory insects that protect your veggies.
- Nasturtiums: These are fantastic trap crops. Aphids love them more than your artichokes, drawing pests away. Their peppery leaves are also edible.
- Marigolds (French & African): Their roots release a substance that suppresses nematodes. These microscopic soil pests can harm artichoke roots. Plant them around the artichoke’s base.
- Calendula: Often called pot marigold, it attracts hoverflies and ladybugs. Their larvae consume huge numbers of aphids.
- Borage: This is a powerhouse companion. It repels tomato hornworms and cabbage worms, which might bother artichokes. It also adds trace minerals to the soil when it decomposes.
Best Herb Companions
Herbs are strong-scented and confuse or repel common garden pests with their aromatic oils.
- Tarragon: Its scent is believed to deter many pests. It also grows well in the same sunny, well-drained conditions artichokes prefer.
- Parsley: When allowed to flower, parsley attracts parasitic wasps that target harmful caterpillars. It makes a nice low-growing border.
- Mint (Caution Advised): Mint repels ants and aphids effectively. However, it is incredibly invasive. Always plant mint in a pot, then sink the pot into the soil near your artichokes.
- Dill: Attracts ladybugs, lacewings, and wasps that prey on artichoke pests. It’s a great all-around garden helper.
Best Vegetable Companions
Some vegetables get along with artichokes because they have different root depths or nutrient needs.
- Members of the Cabbage Family (Brassicas): This includes kale, broccoli, and Brussels sprouts. They are heavy feeders, but artichokes have deep roots that can access nutrients deeper down, reducing competition.
- Leafy Greens: Lettuce, spinach, and Swiss chard have shallow roots. They provide a living mulch, keeping soil cool and moist around the artichoke’s base.
- Root Vegetables: Radishes, carrots, and beets occupy a different soil layer. They break up soil compaction, which benefits artichoke root growth.
- Peas and Beans: These legumes fix nitrogen in the soil. Artichokes are moderate nitrogen feeders and can use this extra nutrient boost, especially in their early growth stages.
- Tall, Heavy Feeders: Corn and sunflowers compete aggressively for light and nutrients. They will shade out and starve your artichokes.
- Other Heavy Feeders in the Nightshade Family: Tomatoes, potatoes, and eggplants need lots of the same nutrients as artichokes. Planting them together leads to competition and weaker plants all around.
- Fennel: This is the classic bad neighbor. Fennel secretes substances from its roots that inhibit the growth of many plants, including artichokes. Plant it in a seperate bed entirely.
- Choose the Right Artichoke Spot: Select a site with full sun (6-8 hours) and excellent drainage. Amend the soil with plenty of compost, as artichokes are hungry plants.
- Plant Your Artichoke: Whether from seed or crown, give it plenty of room. Mature plants can spread 4-6 feet wide. Plant it as the centerpiece.
- Add Your Companions: Plant taller flowers like sunflowers (in a different bed!) or borage slightly to the north so they don’t shade the artichoke. Circle the artichoke base with marigolds and nasturtiums. Interplant shallow-rooted greens and herbs in the remaining spaces.
- Mulch and Maintain: Apply a thick layer of organic mulch like straw or wood chips. This conserves water and suppresses weeds. Water deeply and consistently, especially during dry spells.
Plants to Avoid Near Artichokes
Just as some plants help, others can hinder. Here’s what to keep at a distance.
Why Companion Planting Works for Artichokes
Understanding the “why” helps you make better planting choices. Artichokes have specific needs companion planting addresses.
Pest Management
Artichokes can be bothered by aphids, slugs, and certain caterpillars. Strong-smelling herbs mask the artichoke’s scent. Trap crops like nasturtiums pull pests away. Flowers bring in insects that eat those pests.
Soil Health and Structure
Artichokes prefer deep, fertile, well-draining soil. Deep-rooted companions like daikon radish break up hardpan. Nitrogen fixers like peas add fertility. Low-growing greens prevent soil erosion and retain moisture.
Efficient Use of Space
Artichokes are large, perennial plants that take up space. Using the area around them for quick-growing lettuces or herbs maximizes your garden’s yield. This is called intercropping.
Pollinator Attraction
While we eat artichokes before they flower, if you let one bud bloom, it’s a stunning giant purple thistle. Companion flowers ensure pollinators are already in your garden, benefiting every other flowering plant you grow.
How to Plan and Plant Your Artichoke Guild
A “guild” is a group of plants that support a central species. Here’s how to build one for your artichokes.
Troubleshooting Common Artichoke Problems
Even with companions, issues can arise. Here’s how to identify and fix them.
Yellowing Leaves
This often signals overwatering or poor drainage. Artichokes hate wet feet. Ensure your soil is sandy loam and you’re not watering too frequently. Sometimes it can also be a nutrient deficiency, so a side-dressing of compost can help.
Small or Few Buds
This usually means the plant needs more food. Artichokes are heavy feeders. Apply a balanced organic fertilizer or more compost in early spring. Also, ensure it’s not shaded by faster-growing companions.
Aphid Infestations
If aphids appear despite your nasturtiums, blast them off with a strong jet of water from the hose. You can also introduce ladybugs to your garden. A mild soapy water spray (1 tsp mild soap per liter of water) is a effective direct treatment.
Seasonal Companion Planting Tips
Your artichoke bed can be productive across multiple seasons, especially in milder climates.
Spring
Plant your artichoke crowns or seedlings. Sow quick-growing cool-season companions like lettuce, radishes, and parsley around them. Plant calendula and nasturtium seeds.
Summer
As the artichoke matures and produces buds, ensure companions aren’t crowding it. Harvest leafy greens to give the artichoke more space. Dill and borage will be in full swing attracting beneficials.
Fall & Winter
After the main harvest, cut back the artichoke stalks. Plant a cover crop of clover or vetch around it to fix nitrogen and protect the soil. In zones 7 and above, artichokes will over-winter as perennials.
FAQ: Artichoke Companion Planting
Q: Can I plant garlic with artichokes?
A: Yes, garlic can be a good companion. Its strong scent may deter some pests. However, plant it at the dripline, not right at the base, as both need good air circulation.
Q: How far apart should I plant companions from my artichoke?
A: For low-growing herbs and greens, 12-18 inches from the artichoke’s base is fine. For larger plants like borage, give them 2-3 feet so they don’t compete for light and root space.
Q: Do artichokes need a pollinator to produce the bud we eat?
A: No. The edible part is the immature flower bud. It is harvested long before pollination is necessary. Letting one bud flower is great for pollinators but reduces your edible yield slightly.
Q: What is the best mulch for artichokes?
A: Straw, shredded leaves, or well-rotted compost make excellent mulch. They retain moisture, suppress weeds, and break down to feed the soil. Avoid piling mulch directly against the stem to prevent rot.
Q: Can I grow artichokes in pots with companions?
A> You can, but choose a very large pot (at least 20 gallons) for the artichoke itself. You might underplant it with a few shallow-rooted herbs like thyme or parsley, but avoid overcrowding the container.
Implementing these companion planting strategies takes a little planning, but the results are worth it. Your artichokes will be more resilient and productive. Your garden will become a more balanced ecosystem with fewer pests and healthier soil. Start by choosing two or three companions from the list and observe the difference they make. You’ll likely find that your entire garden begins to thrive.
