Companion planting is a time-honored gardening practice that involves growing certain plants together to help them thrive. This technique, utilized by gardeners for centuries, is based on the understanding that some plants benefit from each other’s presence, while others may hinder growth or cause problems.
When it comes to sorrel, an herb known for its tangy, lemony flavor and vibrant green leaves, companion planting can play a crucial role in boosting its growth, enhancing flavor, and reducing pest problems.
In this post, we’ll dive into why you should consider companion planting for sorrel, explore the best companion plants to grow with it, discuss which plants to avoid, and provide tips on how to successfully grow companion plants alongside your sorrel.
Why You Should Consider Companion Planting for Sorrel

Sorrel is a hardy perennial herb that thrives in cool climates and enjoys a spot with full to partial sunlight. It’s often grown for its leaves, which are used in soups, salads, and sauces. However, like all plants, sorrel benefits from the right companions. Companion planting isn’t just about aesthetics or maximizing space in the garden; it’s about creating a harmonious ecosystem where plants work together to enhance each other’s growth, flavor, and resistance to pests and diseases.
The benefits of companion planting for sorrel are numerous:
- Pest Control: Many companion plants have natural insect-repellent properties. By planting certain herbs and flowers near sorrel, you can ward off pests that may otherwise damage your crop.
- Improved Growth: Some plants enhance soil nutrients, attract beneficial insects, or even provide shade, all of which can support sorrel’s health and productivity.
- Flavor Enhancement: Companion plants can even influence the flavor of sorrel. For example, certain herbs or flowers may enhance the taste of sorrel leaves or keep them tender for longer periods.
- Better Space Utilization: Sorrel can sometimes grow quite large, so it benefits from being paired with smaller, more compact plants that help maximize garden space.
By considering companion planting, you can create an optimal growing environment for sorrel that improves yield, health, and flavor.
Best Companion Plants for Sorrel
When choosing companion plants for sorrel, it’s essential to consider plants that will thrive in similar soil, sunlight, and water conditions. Sorrel is relatively easy to care for and grows best in slightly acidic, well-drained soil. Here are some of the best companion plants to grow alongside sorrel:
1. Garlic
Garlic is an excellent companion plant for sorrel because it helps repel pests such as aphids and slugs. Its strong aroma deters many insects, preventing them from causing harm to your sorrel. Additionally, garlic’s natural antifungal properties can help protect sorrel from fungal infections. Garlic also has shallow roots, so it won’t compete for space or nutrients with your sorrel.
2. Chives
Chives are another great companion for sorrel. They help ward off aphids and other small pests that might otherwise target your sorrel. Chives are also beneficial because they won’t overshadow or outcompete sorrel, as they grow in a compact, clump-forming manner. Their mild flavor can also enhance the taste of sorrel in dishes like salads and soups.
3. Nasturtiums
Nasturtiums are known for their ability to attract beneficial insects, including pollinators like bees and butterflies. These flowers also help deter aphids and other harmful pests, making them a perfect companion for sorrel. Nasturtiums grow as ground cover, which can help keep the soil moist and reduce weeds, while their vibrant flowers and leaves can add color and texture to your garden.
4. Strawberries
Strawberries make excellent companions for sorrel, as their low-growing nature provides natural ground cover that helps suppress weeds. Strawberries and sorrel share similar growing conditions, such as a preference for slightly acidic, well-drained soil, and they can help keep each other’s roots cool in the heat of the summer. Additionally, strawberries and sorrel grow at different heights, ensuring they don’t compete for sunlight.
5. Calendula
Calendula, or marigold, is another great companion plant for sorrel. It helps attract beneficial insects like ladybugs, which feed on aphids and other pests that may damage sorrel. Calendula also has natural antifungal properties that can help protect sorrel from diseases like powdery mildew. Plus, the bright yellow or orange flowers of calendula add a burst of color to your garden.
6. Cabbage Family (Brassicas)
Brassicas like cabbage, kale, and broccoli can grow well with sorrel, as long as there’s enough space between them. These plants benefit from the nitrogen-rich environment sorrel provides, and the two can help each other by attracting different types of beneficial insects. However, it’s important to ensure that sorrel has enough room to spread, as brassicas can also be large plants that may shade out sorrel if planted too close together.
Plants to Avoid Planting Near Sorrel

While companion planting can benefit sorrel, there are some plants that should be kept at a distance. Certain plants may hinder sorrel’s growth by competing for nutrients, water, or light, while others might attract pests or diseases that could negatively impact sorrel. Here are some plants to avoid planting near sorrel:
1. Fennel
Fennel is a plant that should be avoided near sorrel, as it can release chemicals that inhibit the growth of nearby plants, including sorrel. These chemicals can stunt the growth of sorrel and reduce its yield. Additionally, fennel can be quite invasive, growing tall and spreading quickly, which could overshadow your sorrel and compete for resources.
2. Carrots
Carrots and sorrel don’t make great companions because they have similar root systems, which means they will compete for space and nutrients underground. Sorrel’s deep taproot may also interfere with the growth of carrots, leading to stunted growth or poor root development. It’s best to keep them separated in the garden to avoid these issues.
3. Potatoes
Potatoes can also be problematic when planted near sorrel, as they can attract pests like aphids and Colorado potato beetles. These pests can also damage sorrel, reducing its growth and overall health. Potatoes can also shade out sorrel, especially if they are planted too close together, depriving sorrel of the sunlight it needs to thrive.
4. Tomatoes
While tomatoes and sorrel both enjoy sunny spots in the garden, they may not be the best companions. Tomatoes can attract pests like hornworms and aphids, which can also affect sorrel. Moreover, tomatoes are heavy feeders and may compete with sorrel for nutrients, leading to nutrient imbalances and poor growth for both plants.
Tips for Growing Companion Plants with Sorrel
When growing companion plants with sorrel, there are several tips to keep in mind to ensure success:
- Consider Planting Patterns: To maximize space and minimize competition, plant companion plants in a way that allows each plant enough room to grow. For example, place shorter plants like garlic and chives around the perimeter of your sorrel patch, while taller plants like nasturtiums or brassicas can be placed on the edges where they won’t overshadow sorrel.
- Rotate Your Crops: Companion planting is not only about the right pairings but also about crop rotation. After each growing season, rotate your plants to avoid depleting the soil of specific nutrients and to prevent the buildup of pests or diseases.
- Monitor Watering Needs: Different companion plants may have varying water requirements. Ensure that you’re providing adequate irrigation for all plants while avoiding overwatering, which could lead to root rot or fungal diseases.
- Mulch for Weed Control: Applying mulch around your sorrel and companion plants can help keep weeds at bay and maintain moisture in the soil. Organic mulch such as straw or compost also adds nutrients to the soil as it breaks down.
- Attract Pollinators: Many companion plants, such as nasturtiums and calendula, can attract pollinators like bees and butterflies. These insects help improve the overall health of your garden, and their presence will ensure that sorrel flowers are pollinated if you choose to let them bloom.
- Harvest Regularly: Sorrel is a fast-growing herb that benefits from frequent harvesting. Regular harvesting encourages the plant to produce new leaves, which keeps it healthy and productive throughout the season.
Conclusion
Companion planting for sorrel is a fantastic way to optimize your garden, increase crop yields, and minimize pest issues. By choosing the right companions—such as garlic, chives, and nasturtiums—you can create an environment that benefits both your sorrel and other plants.
At the same time, be mindful of which plants to avoid, such as fennel and potatoes, which can hinder sorrel’s growth. With a little planning and attention, companion planting will allow your sorrel to thrive while helping your garden flourish as a whole.
