Swiss Chard’s Best Friends: Top Companion Plants Unveiled!

As a lifelong gardener in Wisconsin, I always seek ways to create a healthy, sustainable garden ecosystem. One technique I highly recommend is companion planting – choosing specific plant pairings that can benefit each other when grown together. In this article, I’ll share my experiences and advice on excellent companion plant matches for Swiss chard. With the right companion plants, you can improve your Swiss chard crop’s growth, flavor, and pest resistance.

An Overview of Companion Planting

Before we discuss Swiss chard, let’s review the basics of companion planting. The key goal is to create biodiverse gardens full of plants that benefit and support one another. Well-matched companion plants provide nutrients, pest control, shade/support, and more for their plant neighbors.

Benefits of companion planting with Swiss chard

Benefits include:

  • Enhancing flavor
  • Boosting nutrients
  • Controlling pests
  • Improving crop yields
  • Promoting biodiversity

Due to its hardy nature and diversity of cultivars, Swiss chard is an ideal candidate for companion planting. By intermixing Swiss chard with plants that enrich the soil, repel pests, and fill space efficiently, you can help your chard – and your entire garden – thrive.

Top Companion Plants for Swiss Chard

Through years of experimenting in my Wisconsin garden, I’ve discovered many excellent companion plants that benefit chard. Here are some of my favorites in different plant categories:

Companion plants to protect Swiss chard from disease

Leafy Greens and Herbs

Lettuce, spinach, arugula, parsley, cilantro, basil, and other leafy greens make great companions for chard. They have similar light and soil needs, so interplanting creates an efficient and lush landscape. Plus, the shallow roots don’t compete for space underground. Herbs like basil and parsley also repel pests, protecting the chard.

Success story: Lettuce provides shade for chard seedlings. Both mature around the same time for harvest.

Root Vegetables

Carrots, radishes, turnips, and beets work well with chard. Plant along border rows so substantial root growth doesn’t overwhelm Swiss chard’s shallower roots. They tend to repel each other’s common pests too. Also, root crops like radishes mature quickly, letting you plant a second crop in their place in succession.

Success story: Carrots and Swiss chard enhanced each other’s flavor when planted together.

Legumes & Nitrogen Fixers

Beans, peas, and clover put nutrients back into the soil through nitrogen fixation. This benefits nitrogen-loving plants like Swiss chard. Plus, they don’t compete much for space below ground. Some options also provide helpful trellising and coverage. Just be sure to provide support structures for climbing varieties.

Success story: Bush beans interplanted with Swiss chard added nitrogen to the soil, providing an extra edible crop without competing for space.

Flowering Plants

Don’t overlook cheery flowering plants like marigolds, nasturtiums, calendulas, and borage. They attract pollinators, which boost vegetable yields through better pollination. Certain flowers also repel common Swiss chard pests like aphids, mites, and nematodes. Splashes of blossoms create a visually appealing edible landscape.

Success story: Marigolds repelled nematodes and added a pop of color next to vibrant red Swiss chard.

Plants to Avoid Pairing with Swiss Chard

While many plants complement chard’s needs, a few options are too competitive. They rob nutrients, sunlight, and space for healthy Swiss chard growth. Through trial and error, I don’t recommend pairing your Swiss chard with:

  • Broccoli family members
  • Strawberries
  • Tomatoes
  • Potatoes
  • Corn
  • Pole beans

Pay attention if your chard shows stunted growth, yellowing leaves, bolting, or low yields. This can indicate an incompatible planting scheme. Just adjust for the next growing season. Little garden experiments like this are all part of the fun!

How Companion Plantings Benefit Swiss Chard

Now that we’ve covered lots of potential plant matches with Swiss chard let’s examine why these companionships are so successful:

Enriching the Soil Together

You can enrich soil nutrition by pairing Swiss chard with legumes, dynamic accumulators like comfrey, and natural fertilizers like compost. This leads to better growth for the chard and all its plant neighbors. It also supports underground healthy microbial ecosystems – the “soil food web” essential for plant health.

Pest Control Through Diversity

A wide diversity of plants with different pest-fighting strengths makes it harder for invading bugs to take hold. Herbs like dill and chamomile repel damaging spider mites. Marigolds target nematodes. Borage attracts bees and predatory insects that eat aphids. A biodiverse garden is a resilient garden!

Efficient Use of Garden Space

When plants fill complementary niches above and below ground, you maximize productivity in every square foot. Shallow and deep-rooting plants can share space. Tall sun lovers can provide needed shade for shorter greens. Quickly maturing radishes let you succession plant heat-loving crops later. The possibilities are endless!

Flavor Enhancement

When grown next to Swiss chard, many fruits, herbs, edible flowers, and vegetables add delicious complementary flavors. The roots of my chard plants intermingled with hearty carrot companions, creating a dynamic sweet taste. Nasturtiums, borage, and marigolds provided peppery notes and visual delight. Kids love picking edible flowers to spice up their salad greens!

Designing Your Swiss Chard Companion Garden

Now comes the fun part – using this companion knowledge to design a thriving edible garden! Here are some tips:

Go Big with Raised Beds

For intensive planting, raised garden beds excel. They offer ample room for abundant plants while keeping pathways accessible for care and harvesting. When filling your raised beds each season, focus on water retention, drainage, and nutrient levels.

Think Outside the Box with Containers

Don’t have space for in-ground plots? No problem! Swiss chard and companions like herbs, lettuce, radishes, and bush beans thrive in containers together. Focus on soil quality, drainage, matcher watering needs, and sunlight access on patios, porches, or anywhere you want to grow.

Add Vertical Space with Support Structures

Make the most of small spaces by adding vertical growing space. Sturdy trellises for climbers like peas and pole beans allow you to stack multiple companion layers. This opens up precious ground-level real estate for chard and other low-growing companions.

Intercrop for Efficiency & Pest Protection

Intercropping means planting quick-growing species between rows of slower-growing ones, which increases productivity. For example, lettuces and Asian greens fill space while chard matures. You can also underplant beneficial insect-attracting flowers within chard rows.

Succession Plant for Nonstop Harvests

Succession planting prevents gaps in harvests by following quick crops with longer yields. For example, in early spring, plant radishes with chard. After harvesting radishes in 30 days, space opens up for replanting heat-loving crops like basil.
