But what if I told you there’s a secret to creating a garden that largely takes care of itself? A garden where plants help each other thrive, fight off pests, and produce bigger, more flavorful harvests with less work from you.

This isn’t magic; it’s the time-tested practice of companion planting. In this complete what veggies to grow together guide, we’re going to unlock the simple science of plant partnerships. You’ll learn which veggies are best friends, which are sworn enemies, and how to create a vibrant, self-sustaining ecosystem right in your backyard.

The Magic of Companion Planting: Why It’s More Than Just Garden Folklore

Companion planting is an age-old technique that involves placing different crops near each other to create a mutually beneficial relationship. Think of it as building a happy, cooperative neighborhood in your garden bed. This approach is the cornerstone of sustainable what veggies to grow together practices.

Understanding the benefits of what veggies to grow together can completely change your gardening strategy. It’s not just about saving space; it’s about creating a smarter, healthier, and more resilient garden.

Here’s what you can expect when you get the pairings right:

  • Natural Pest Control: Some plants, like marigolds or aromatic herbs, release scents that repel common pests. Others act as “trap crops,” luring pests away from your more valuable vegetables. For example, planting nasturtiums near your squash can help draw aphids away.
  • Attracting Beneficial Insects: Flowering companions like borage and alyssum are magnets for pollinators (hello, more squash and cucumbers!) and predatory insects like ladybugs and lacewings, which feast on pests.
  • Improved Soil Health: Legumes, like beans and peas, are nitrogen-fixers. They pull nitrogen from the air and store it in their roots, enriching the soil for heavy-feeding neighbors like corn or tomatoes.
  • Better Growth and Flavor: Some gardeners swear that certain pairings enhance the taste of their crops. The most famous example is planting basil next to tomatoes—it’s said to improve tomato flavor and repel tomato hornworms.
  • Maximizing Garden Space (Trellising): You can use the natural growth habits of plants to your advantage. Vining plants like peas can climb up tall companions like corn or sunflowers, saving you precious ground space.

Getting Started: How to Plan Your Veggie Partnerships

Before you start digging, it’s helpful to understand the basic principles. Learning how to what veggies to grow together is all about observing and thinking like nature. Follow these best practices to set yourself up for success.

Think in Plant Families

Plants in the same family often attract the same pests and diseases and compete for the same nutrients. For example, planting tomatoes, peppers, and potatoes (all in the nightshade family) close together can create a buffet for pests and increase the risk of blight spreading among them.

Try to rotate your plant families each year and avoid grouping too many members of the same family in one spot.

Consider Growth Habits and Needs

A successful garden community works together above and below ground. Pair tall, sun-loving plants with low-growing, shade-tolerant ones. For instance, you can plant lettuce or spinach in the shade cast by your towering tomato plants during the heat of summer.

Use Herbs and Flowers Generously

Don’t just think about vegetables! Aromatic herbs and flowers are the secret weapons of companion planting. They are essential for an eco-friendly what veggies to grow together strategy.

Herbs like rosemary, thyme, and mint can confuse pests with their strong scents. Flowers like marigolds fight off soil nematodes, while sweet alyssum provides ground cover that chokes out weeds and attracts beneficial hoverflies.

Ready for the fun part? Here are some of the most reliable and effective plant partnerships that gardeners have trusted for generations. Think of these as your go-to cheat sheet for a harmonious garden.

The Three Sisters: Corn, Beans, and Squash

This is the most famous companion planting trio, practiced for centuries by Indigenous peoples of North America. It’s a perfect symbiotic system:

  • The corn provides a natural trellis for the beans to climb.
  • The pole beans stabilize the corn stalks and fix nitrogen into the soil, feeding the corn and squash.
  • The large, sprawling squash leaves act as a living mulch, shading the ground to retain moisture and suppress weeds.

Tomatoes and Their Best Friends

Tomatoes are a garden staple, and they have many friends that help them thrive. Keep them away from their foes like potatoes and fennel.

  • Basil: This is the number one companion for tomatoes. It’s said to repel tomato hornworms and whiteflies and even improve the tomato’s flavor.
  • Carrots: Planted near tomatoes, carrots can help loosen the soil. Just be sure to give them enough space so the tomato roots don’t crowd them out.
  • Borage: This beautiful, flowering herb deters tomato hornworms and attracts beneficial pollinators.
  • Marigolds: A classic in the veggie patch, French marigolds release a substance that deters root-knot nematodes in the soil.

Carrots, Onions, and Leafy Greens

This group of root veggies and leafy greens can be cleverly combined to ward off pests.

  • Carrots and Onions (or Leeks): The strong smell of onions and leeks helps to mask the scent of carrots, deterring the dreaded carrot rust fly. In return, carrots may help repel onion flies.
  • Lettuce and Chives: Chives or garlic can help repel aphids that often plague tender lettuce leaves.
  • Rosemary and Carrots: Another aromatic herb to the rescue! Rosemary’s scent helps to deter the carrot rust fly.

Brassicas (Broccoli, Cabbage, Kale) and Their Protectors

The brassica family is notorious for attracting cabbage worms and aphids. Luckily, they have many aromatic guardians.

  • Aromatic Herbs: Thyme, dill, rosemary, and sage are excellent companions. Their strong scents confuse the cabbage moth, making it harder for her to find a place to lay her eggs.
  • Onions: Planting onions nearby can also help deter cabbage worms and other pests.
  • Nasturtiums: These edible flowers are a fantastic “trap crop.” Aphids love them and will often flock to them instead of your precious broccoli and kale.

Garden Foes: Veggies You Should Never Plant Together

Just as important as knowing what to plant together is knowing what to keep apart. Some plants are allelopathic, meaning they release biochemicals that can inhibit the growth of their neighbors. Others simply compete too aggressively for resources.

  • Fennel: This is the garden’s loner. Most plants dislike it. It secretes a substance that can inhibit the growth of everything from beans to tomatoes. Give it its own separate patch.
  • Beans and Alliums (Onions, Garlic, Chives): The allium family can stunt the growth of bush and pole beans. Keep them on opposite sides of the garden.
  • Potatoes and Tomatoes: Both are heavy feeders from the same nightshade family and are susceptible to early and late blight. Planting them together can speed up the spread of disease and deplete soil nutrients.
  • Cabbage and Tomatoes: Tomatoes can stunt the growth of cabbage and other brassicas.
  • Lettuce and Broccoli: Broccoli can release a substance that is toxic to lettuce seedlings.

A healthy, eco-friendly what veggies to grow together strategy also includes building healthy soil, encouraging biodiversity, and using physical barriers like row covers when needed.
