Gut-Friendly Gardening: Grow These Vegetables and Herbs for Better Digestion

Martha Carlin | Mar 24, 2025 |

Growing your own food is rewarding—but did you know it can also improve digestion? Certain vegetables and herbs naturally support gut health by balancing bacteria, aiding digestion, and reducing bloating? Many vegetables and herbs contain fiber, enzymes, and plant compounds that help balance gut bacteria, encourage smooth digestion, and reduce bloating.

Better yet, by cultivating a healthy soil microbiome, you can boost the nutrient density of your homegrown produce—helping your gut thrive from the ground up. Let’s explore the best digestion-supporting plants to grow this season and how BiotiQuest’s Yield & Shield can enrich your garden’s soil microbiome for a healthier harvest.

Getting Ready for Spring on the Farm

As I prepare my own garden for the season, I’m reminded of the patience and care that gardening—and gut health—both require. This is my first year harvesting asparagus, a perennial I planted last spring. Asparagus takes time to establish—often a couple of years before you can enjoy a full bounty—but this year, I’m expecting to see the early signs of growth just around the corner.  .

Last year, I ran into some soil pH issues that needed adjusting, which reminded me how much the health of the soil determines the vitality of our plants (just like how our gut microbiome impacts our overall health). With a bit of patience and soil support, I’m looking forward to seeing what this year’s crop brings!

Why Grow Your Own Gut-Friendly Foods?

The gut is at the root of our health, influencing everything from digestion to immune function. Many store-bought vegetables are grown in depleted soils, reducing their nutrient content. But when you grow your own food, you have full control over how your plants are nourished. 

We discussed this during our book club conversation about What Your Food Ate by David R. Montgomery & Anne Biklé. You can watch the reply here!

By supporting microbial diversity in your garden’s soil, you can increase essential nutrients like magnesium, potassium, and B vitamins—all crucial for digestion. Unfortunately, modern farming practices strip soil of essential microbes, reducing the nutrient quality of store-bought vegetables. The good news? You can restore microbial balance in your own garden with Yield & Shield—a probiotic blend that enhances soil health, boosts nutrient absorption, and helps your plants (and gut) thrive.

The Best Vegetables and Herbs for Digestion

Spring is the perfect time to plant a variety of gut-loving vegetables and herbs. Here’s what to grow and why these plants are so beneficial:

Vegetables That Support Digestion

🥕 Carrots – Rich in fiber and beta-carotene, which help maintain a strong gut lining and encourage beneficial bacteria growth. Sow seeds directly in early spring for a crisp, nutrient-dense harvest.

🥬 Cabbage – Whether eaten raw, cooked, or fermented (as sauerkraut), cabbage provides fiber and prebiotics that support gut health. Start seeds indoors in late winter or plant directly in early spring.

🌿 Fennel – Known for its soothing effects on digestion, fennel can help reduce bloating and gas. Start seeds outdoors after the last frost.

🍠 Jerusalem Artichokes (Sunchokes) – Packed with inulin, a prebiotic fiber that feeds beneficial gut bacteria. Plant tubers in early spring and harvest in the fall.

🍃 Swiss Chard & Spinach – High in magnesium, which helps relax the intestines and prevent constipation. These greens love cool spring temperatures.

🥒 Zucchini – A hydrating, fiber-rich vegetable that’s gentle on digestion. Start seeds indoors in early spring or sow directly after the last frost.

Herbs That Aid Digestion

🌱 Peppermint – A well-known digestive soother that helps with bloating and cramping. Best grown in pots to keep it from spreading.

🌼 Chamomile – Known for its calming effects on the digestive system, chamomile is easy to grow from seed in early spring.

🍋 Lemon Balm – A gentle herb that eases gas, bloating, and stress, which plays a key role in gut health.

🌿 Dill – Both the leaves and seeds promote digestive enzyme production. Plant in early spring for a fresh, aromatic addition to meals.

🧄 Oregano & Thyme – Antimicrobial herbs that support a balanced gut microbiome. These perennials thrive in well-drained soil and full sun.

🌿 Parsley & Cilantro – Both support digestion and detoxification while adding a burst of flavor to dishes.

Boosting Your Garden with Soil Microbes

Just as our gut thrives on a diverse microbiome, so does the soil. Healthy, microbially rich soil enhances plant growth, increases nutrient density, and helps break down toxins like glyphosate. Yield & Shield is designed to do just that—introducing beneficial microbes that restore soil health and improve nutrient availability.

I’ve seen firsthand how Yield & Shield makes a difference, especially after working to correct my soil’s pH last year. It’s incredible to witness how a thriving soil microbiome leads to stronger, more resilient plants.

Getting Started: Your Spring Planting Guide

  • Prepare the soil – Mix in compost and apply Yield & Shield to boost microbial diversity.
  • Plant at the right time – Many gut-friendly vegetables thrive in early spring before the summer heat arrives.
  • Water consistently – Keep the soil moist but not waterlogged to encourage healthy root development.
  • Encourage biodiversity – Companion planting with flowers and herbs can attract pollinators and beneficial insects.

By growing your own digestion-supporting plants and nurturing your garden’s microbiome, you’re cultivating more than just food—you’re fostering a deeper connection to nature and your own well-being.
