Tarragon Companion Plants

Planting tarragon near certain vegetables can boost their growth while confusing common garden pests. If you are looking for the best tarragon companion plants, you have come to the right place. This herb is not just a kitchen staple; it is a hardworking ally in the garden that can improve the health of your crops.

Tarragon is a perennial herb with a distinct anise-like flavor. It is a fantastic addition to any vegetable patch, but it does have specific needs. In this guide, we will walk you through the best neighbors for tarragon, which plants to avoid, and how to get the most out of this aromatic herb.

Why Use Tarragon Companion Plants?

Companion planting is the practice of growing different plants together for mutual benefit. Tarragon is particularly useful because it releases chemicals from its roots that can help other plants. It also has a strong scent that confuses pests looking for their favorite foods.

Tarragon is a low-maintenance plant that thrives in poor, well-drained soil. This makes it a great choice for the edge of a garden bed. It does not need rich soil, so it will not compete with your heavy-feeding vegetables. Instead, it works as a support system for the rest of your garden.

Benefits Of Growing Tarragon Nearby

There are several key benefits to using tarragon as a companion. First, it is a natural pest deterrent. The essential oils in the leaves mask the scent of nearby plants. This is especially effective against aphids, ants, and certain beetles.

Second, tarragon is a great indicator plant. If it is thriving, your soil conditions are likely good. It also attracts beneficial insects like parasitic wasps and hoverflies. These insects prey on common garden pests like caterpillars and aphids.

Finally, tarragon can improve the flavor of certain vegetables. While this is hard to prove scientifically, many gardeners swear by it. The aromatic compounds in tarragon can influence the growth of nearby plants, making them more robust and flavorful.

Now, let’s get into the specific plants that work well with tarragon. The best companions are those that share similar growing conditions or those that benefit from tarragon’s pest-repelling properties.

Best Vegetables To Plant With Tarragon

Tarragon is an excellent companion for most root vegetables and leafy greens. Here are the top choices for your vegetable garden:

Eggplant: Tarragon is said to improve the growth and flavor of eggplant. It also helps to deter flea beetles, which are a common pest for this crop.
Peppers: Both sweet and hot peppers benefit from being near tarragon. The strong scent of the herb confuses aphids and spider mites that often attack pepper plants.
Tomatoes: This is a classic pairing. Tarragon repels hornworms and whiteflies. It also seems to help tomatoes produce more fruit.
Potatoes: Planting tarragon near potatoes can help repel the Colorado potato beetle. This is a major pest that can decimate a potato crop.
Lettuce and Greens: Tarragon provides a bit of shade and helps to keep slugs and snails away from tender lettuce leaves.
Carrots: Tarragon can help mask the scent of carrots, making it harder for carrot root flies to find them.

Herbs That Thrive With Tarragon

Tarragon does not mind sharing space with other herbs, as long as they have similar water needs. Since tarragon prefers dry conditions, you should choose herbs that do not require constant moisture.

Sage: Both are Mediterranean herbs that like dry, sandy soil. They make great neighbors and do not compete for nutrients.
Thyme: This low-growing herb is a perfect ground cover for around the base of tarragon. It helps to keep the soil cool and suppresses weeds.
Rosemary: Another drought-tolerant herb that pairs well with tarragon. They both attract pollinators and beneficial insects.
Parsley: While parsley likes a bit more water, it can still grow well near tarragon if you water the base of the parsley only. The tarragon will help protect it from aphids.

What To Avoid Planting Near Tarragon

Not all plants are good friends with tarragon. Some plants have conflicting needs or can actually hinder each other’s growth. Here is what you should avoid:

Cucumbers: Cucumbers need a lot of water and rich soil. Tarragon prefers dry, poor soil. They will likely compete, and one of them will suffer.
Fennel: Fennel is allelopathic, meaning it releases chemicals that inhibit the growth of other plants. It should be kept far away from most herbs, including tarragon.
Mint: Mint is incredibly invasive and will quickly take over the area where tarragon is growing. They also have different water needs.
Basil: Basil loves rich, moist soil and full sun. Tarragon prefers drier conditions. They are not a good match in the same bed.

How To Plant Tarragon For Best Results

To get the most out of your tarragon companion plants, you need to set up your garden correctly. Here is a step-by-step guide to planting tarragon in your vegetable patch.

Step-By-Step Planting Guide

Choose the right spot: Tarragon needs full sun to partial shade. It prefers well-drained soil with a pH between 6.5 and 7.5. Avoid areas where water tends to pool.
Prepare the soil: Do not add compost or manure. Tarragon actually prefers poor soil. Too much organic matter will dilute the essential oils and reduce the flavor.
Plant the tarragon: Dig a hole slightly larger than the root ball. Place the plant in the hole and backfill with soil. Space plants about 18 inches apart.
Water lightly: Water the plant in after planting, but then let the soil dry out completely before watering again. Overwatering is the most common way to kill tarragon.
Add companions: Plant your chosen companions around the tarragon. Make sure they are far enough away that they do not shade the tarragon too much.
Mulch with gravel: Use a light gravel or sand mulch around the base of the plant. This helps to keep the roots dry and prevents fungal issues.

Container Gardening With Tarragon

If you are short on space, you can easily grow tarragon in a container. This also gives you more control over the soil conditions. Choose a pot that is at least 12 inches deep and has good drainage holes.

You can plant tarragon with thyme or sage in a large pot. This makes a beautiful and functional display for your patio. Just be sure to use a gritty, well-draining potting mix. Do not use standard potting soil, as it holds too much moisture.

Pest Control Benefits Of Tarragon

One of the main reasons to use tarragon companion plants is for pest control. The herb is a natural insect repellent that can save your vegetable harvest. Here is a closer look at the pests tarragon helps to deter.

Common Pests Tarragon Repels

Aphids: These tiny insects suck the sap from plants and spread disease. Tarragon’s strong scent confuses them and keeps them away.
Ants: Ants are often attracted to the honeydew left by aphids. By repelling aphids, tarragon also discourages ants.
Flea Beetles: These small jumping beetles chew holes in leaves. They are particularly harmful to eggplant and arugula. Tarragon is a proven deterrent.
Tomato Hornworms: These large green caterpillars can strip a tomato plant in days. Planting tarragon nearby helps to mask the scent of the tomatoes.
Colorado Potato Beetles: These striped beetles are a serious threat to potato plants. Tarragon helps to keep them at bay.

Attracting Beneficial Insects

Tarragon does not just repel the bad bugs; it also attracts the good ones. The small, yellowish flowers that appear in late summer are a magnet for beneficial insects. These include:

Parasitic Wasps: These tiny wasps lay their eggs inside pests like caterpillars and aphids. They are incredibly effective at controlling pest populations.
Hoverflies: The larvae of hoverflies feed on aphids. The adult flies are attracted to the nectar of tarragon flowers.
Lacewings: Lacewing larvae are voracious predators of aphids, mites, and other soft-bodied insects.

Improving Flavor With Companion Planting

Many gardeners believe that tarragon improves the flavor of certain vegetables. While this is anecdotal, there is some logic behind it. The aromatic compounds in tarragon can stimulate the production of essential oils in nearby plants.

Eggplant and tomatoes are said to benefit the most from this flavor enhancement. Some gardeners report that peppers become sweeter when grown near tarragon. To maximize this effect, plant the tarragon close to the base of the vegetable, but not so close that they shade each other.

Maintaining Your Tarragon Plants

Tarragon is a hardy plant that does not need much attention. However, a little maintenance will keep it healthy and productive. Here are a few tips for caring for your tarragon.

Watering And Feeding

Tarragon is drought-tolerant and does not like to be overwatered. Water deeply but infrequently. Allow the top inch of soil to dry out completely between waterings. During rainy periods, you may not need to water at all.

Do not fertilize tarragon. Rich soil will cause it to grow tall and leggy, but it will lose its flavor. If you want to feed it, use a light application of bone meal in the spring. That is all it needs.

Pruning And Harvesting

Regular harvesting encourages bushier growth. Cut the stems back to about 4 inches from the ground. This will promote new growth and prevent the plant from becoming woody. You can harvest tarragon from spring through fall.

If you want to dry tarragon, cut the stems just before the flowers open. This is when the essential oil content is at its highest. Hang the stems upside down in a dark, dry place to preserve the flavor.

Frequently Asked Questions

Here are some common questions about growing tarragon with other plants. These answers should help you get the most out of your garden.

Can I Plant Tarragon With Strawberries?

Yes, tarragon can be a good companion for strawberries. The herb helps to repel ants and weevils that might damage the fruit. However, make sure the strawberries do not shade the tarragon too much.

Does Tarragon Come Back Every Year?

Yes, French tarragon is a perennial in most climates. It will die back in the winter and regrow in the spring. However, it is not frost-hardy in very cold regions, so you may need to mulch it heavily or bring it indoors.

Can I Grow Tarragon From Seed?

French tarragon rarely produces viable seeds. It is best to buy a small plant from a nursery or take a cutting from an existing plant. Russian tarragon can be grown from seed, but it has a much weaker flavor.

What Is The Best Time To Plant Tarragon?

The best time to plant tarragon is in the spring, after the last frost has passed. You can also plant it in the early fall. This gives the roots time to establish before the heat of summer or the cold of winter.

Why Is My Tarragon Turning Yellow?

Yellowing leaves are usually a sign of overwatering. Tarragon hates wet feet. Let the soil dry out completely and reduce your watering frequency. If the soil is heavy clay, consider moving the plant to a raised bed or container.

Final Tips For A Thriving Garden

Using tarragon companion plants is a smart, organic way to protect your vegetables. It is a low-effort plant that gives back a lot. Here are a few final tips to ensure success.

First, always plant tarragon in the driest part of your garden. It does not want to be near your irrigation system. Second, do not be afraid to cut it back hard. It will bounce back quickly. Third, remember that tarragon is a slow grower, so do not expect instant results.
