The Best Companion Plants for Tomatoes (And What to Avoid)

Tomatoes are one of the most popular crops to grow in the garden, but they grow even better when they’re planted with the right neighbors.

Companion planting is the practice of growing plants together that benefit one another. Some plants improve soil health, attract beneficial insects, repel pests, or even improve flavor and productivity.

When you choose the right companions, tomatoes can grow stronger, healthier, and produce better harvests.

In my latest video, I share my favorite tomatoes to grow every year and how I start them from seed, along with a few growing tips.

Let’s take a deeper look at some of the best companion plants for tomatoes and a few plants you should avoid planting nearby.


Why Companion Planting Helps Tomatoes

Tomatoes are heavy feeders and can be susceptible to pests like aphids, hornworms, and whiteflies. The right companion plants can help create a more balanced garden ecosystem.

Benefits of companion planting include:

• attracting pollinators
• attracting beneficial insects that control pests
• repelling harmful insects
• improving soil health
• maximizing space in the garden

A diverse garden is often a healthier and more productive garden.


Best Companion Plants for Tomatoes

Here are some of the best plants to grow alongside tomatoes.


Basil

Basil and tomatoes are a classic pairing in both the garden and the kitchen.

Basil helps repel pests such as:

• aphids
• whiteflies
• tomato hornworms

It also attracts beneficial insects and pollinators that help support the garden ecosystem.

Many gardeners also believe basil can enhance tomato flavor, although the biggest benefit is pest control and biodiversity.


Borage

Borage is one of the most powerful companion plants you can grow near tomatoes.

It attracts pollinators such as bees and beneficial insects that help control pests. Borage is also believed to help repel tomato hornworms.

Another benefit is that borage adds minerals to the soil as its leaves break down.

Plus, the beautiful blue flowers make the garden more vibrant.


Marigolds

Marigolds are famous for helping control garden pests.

Their roots release compounds that help suppress certain soil pests, including nematodes.

They also help deter insects like:

• aphids
• whiteflies
• beetles

Planting marigolds around tomatoes can help create a natural pest barrier.


Calendula

Calendula is another excellent companion plant that attracts beneficial insects such as:

• ladybugs
• lacewings
• hoverflies

These insects help control pests like aphids and other small insects that can damage tomato plants.

Calendula is also a wonderful medicinal herb, making it a great dual-purpose plant in the garden.


Onions and Garlic

Members of the onion family can help deter pests that bother tomatoes.

Garlic and onions can repel:

• aphids
• spider mites
• certain beetles

They also take up very little space, making them easy to tuck between tomato plants.


Carrots

Carrots make a great companion for tomatoes because they grow underground and don’t compete for the same space.

The carrot roots help loosen soil, which can improve drainage and soil structure around tomato plants.

They’re also a great example of intensive planting, allowing you to grow more food in the same garden space.


Plants to Avoid Near Tomatoes

While many plants benefit tomatoes, a few should be kept away.


Corn

Corn and tomatoes attract many of the same pests, particularly the tomato fruitworm (which is also the corn earworm).

Planting them together can increase pest pressure in the garden.


Fennel

Fennel is known to inhibit the growth of many nearby plants, including tomatoes.

It is best grown in its own section of the garden.


Potatoes

Tomatoes and potatoes are both part of the nightshade family.

Because of this, they share many of the same diseases, including blight.

Planting them close together can increase the chance of disease spreading.


A Healthy Garden Is a Diverse Garden

One of the best things you can do for your garden is increase plant diversity.

When you grow herbs, flowers, and vegetables together, you create a small ecosystem that supports pollinators, beneficial insects, and healthier soil.

Tomatoes thrive when they are part of a balanced and diverse garden system, rather than grown alone.


Tomatoes are already one of the most rewarding crops to grow, but companion planting can make them even more productive.

Adding plants like basil, borage, marigolds, calendula, onions, and carrots can help create a healthier garden while improving pest control and biodiversity.

A garden filled with many different plants is often more resilient, more productive, and more enjoyable to grow.

Grow More Food in Less Space: The Power of Intensive Planting

If you’ve ever looked at your garden and wished you could grow just a little more food, you’re not alone.

Most gardens are planted using traditional spacing recommendations. Rows are wide, plants are spaced far apart, and a surprising amount of soil ends up exposed.

But there’s another way to grow.

It’s called intensive planting, and it’s one of the most effective ways to produce a lot of food—even in a small space.

This method allows you to grow more vegetables, improve soil health, and reduce weeds, all at the same time.

And the best part? You don’t need more land to do it.


What Is Intensive Planting?

Intensive planting simply means growing plants closer together in a thoughtful way so they work together instead of competing with each other.

Instead of planting in long rows with wide spaces between them, you plant crops in blocks, layers, and combinations that allow you to maximize every inch of soil.

This approach mimics nature much more closely than traditional row gardening.

In nature, plants rarely grow alone. They grow together in communities, helping protect the soil and supporting each other.

When we apply that idea to the garden, something interesting happens:

🌱 The soil stays cooler and holds moisture better
🌱 Weeds have less space to grow
🌱 Pest pressure can decrease
🌱 Yields can increase dramatically


Why Intensive Planting Works So Well

One of the biggest benefits of intensive planting is soil coverage.

Bare soil dries out quickly, loses nutrients, and becomes a perfect place for weeds to take over.

But when plants grow close enough to shade the soil, they create their own little ecosystem.

The leaves act like a living mulch, protecting the soil surface and helping it retain moisture.

This is especially important in hot climates where soil can dry out quickly.

Another benefit is that plants begin to support each other structurally. Tall plants can provide shade for sensitive crops, and sprawling plants can cover soil between larger plants.

When planned correctly, intensive planting can turn a garden into a high-producing system rather than a collection of individual plants.


Crops That Work Especially Well for Intensive Planting

Some crops adapt beautifully to this method.

A few favorites include:

• Lettuce and leafy greens
• Carrots
• Beets
• Bush beans
• Onions
• Radishes
• Spinach
• Herbs

These crops can be planted relatively close together and harvested gradually, allowing space to open as plants mature.

For example, you can plant radishes between slower crops like carrots or cabbage. The radishes will be harvested long before the other plants need the space.

This technique is called interplanting, and it’s a powerful tool for productive gardens.


Vertical Growing Makes Intensive Planting Even Better

Another important piece of intensive gardening is growing upward.

Using trellises, arches, or vertical supports allows you to grow crops like:

• Tomatoes
• Cucumbers
• Peas
• Pole beans
• Melons

When plants grow vertically, they take up less ground space, allowing you to plant additional crops underneath or nearby.

This is one of the easiest ways to dramatically increase the productivity of a garden.


The One Thing Intensive Gardens Need More Of

Because intensive planting produces more crops in the same space, it also means plants will use more nutrients from the soil.

Healthy soil becomes even more important.

Adding compost regularly, feeding plants with organic fertilizers, and maintaining strong soil biology will help keep an intensively planted garden thriving.

When the soil is rich and alive, plants can grow closer together without struggling.


A Garden That Feeds More People

One of my favorite things about intensive planting is how much food it allows you to grow.

With thoughtful planning, even a modest garden can produce an incredible amount of fresh food for your family.

This approach works whether you garden in:

• Raised beds
• Traditional garden plots
• Small backyard gardens
• Homesteads

It’s simply a smarter way to use the space you already have.


Watch the Full Video: How I Grow More Food in the Same Space

If you’d like to see exactly how I use intensive planting in my own garden, I walk through the process step-by-step in this video.

In the video I cover:

✔ How close plants can actually grow
✔ How to combine crops together
✔ Trellis systems that maximize space

Rooted in Renewal: Setting Goals for a Bountiful Gardening Year

As the new gardening season begins, there’s a palpable sense of hope in the air. The crisp mornings and the faint promise of budding greenery remind us that this is a time for renewal, growth, and fresh possibilities. For gardeners, it’s more than just planting seeds; it’s about planting dreams, nurturing aspirations, and fostering a connection with the earth that keeps us grounded and hopeful.

This year, my focus is on self-sufficiency—taking another step closer to producing more of what my family and I need from our own soil. It’s a goal that excites me, but it also comes with its own challenges. Being self-sufficient requires not only effort and dedication but also a good dose of planning and learning from the past.

One of my big goals this year is to keep better records. If there’s one thing I’ve learned over the years, it’s that a well-documented garden is a productive garden. Harvest times, planting schedules, soil amendments, weather patterns—these details might seem small in the moment, but they hold the key to a more fruitful future. This season, I’m committing to jotting down notes regularly, tracking what works and what doesn’t, and using that information to make next year even better.

But let’s face it, no matter how meticulously we plan, life happens. There will be days when the to-do list feels overwhelming, when unexpected challenges pop up, or when something simply doesn’t get done. And that’s okay. This year, I’m reminding myself not to stress over the unchecked boxes or the occasional misstep. Perfection isn’t the goal—progress is.

Gratitude is a key ingredient in this journey. Instead of focusing on what didn’t go as planned, I want to celebrate what did. The first tomato of the season, the joy of harvesting fresh herbs for dinner, the bees buzzing happily around the blossoms—these moments are treasures that deserve our attention and appreciation. When we garden with a heart full of gratitude, every harvest feels like a victory, no matter how small.

So here’s to a new season filled with promise. Let’s dig our hands into the soil, dream big, and embrace the process with patience and joy. Let’s set goals that inspire us, keep records that guide us, and allow ourselves the grace to stumble and learn along the way. And most importantly, let’s take time to marvel at the miracles that unfold in our gardens and in ourselves as we grow.

May your season be bountiful, your heart light, and your gratitude abundant. Happy gardening!

Winter Gardening Hacks by USDA Zones

In addition to the general winter gardening hacks, it’s essential to know what specific actions to take in different USDA hardiness zones, as winters vary widely across regions. Here’s a breakdown of key tasks and hacks for both perennial flower gardens and vegetable gardens, tailored for each zone.


Perennial Flower Garden Hacks by USDA Zone:

USDA Zones 3-5 (Cold Climates, Winter Temps -30°F to -20°F)

  1. When: Late Fall (October-November)
    • Mulching: Apply 4-6 inches of mulch to protect tender perennials like roses or peonies from freezing.
    • Protect with Burlap: Set up burlap barriers around shrubs like boxwoods to prevent desiccation from harsh winds.
    • Cover with Snow: Allow snow to accumulate around plants as an insulating blanket. Avoid removing it unless necessary.
    • Winter Watering: Before the ground freezes, water perennials deeply to prevent winter drought.

USDA Zones 6-7 (Mild Winters, Winter Temps 0°F to 10°F)

  1. When: Early Winter (November-December)
    • Mulching: Use a 2-3 inch mulch layer to protect the root systems of perennials, like lavender or coneflowers, from cold snaps.
    • Pruning: Prune woody perennials like hydrangeas in late winter (February-March) to encourage healthy spring growth.
    • Frost Blankets: On nights with freezing temps, cover tender perennials with frost blankets or old sheets to prevent damage.

USDA Zones 8-9 (Warm Winters, Winter Temps 10°F to 30°F)

  1. When: Late Winter (December-February)
    • Mulching: Use lighter mulching materials like pine straw to keep the soil warm, without suffocating the plants.
    • Watering: Continue occasional deep watering, as winter drought can affect growth.
    • Pruning: Early winter is the ideal time to prune roses and other flowering shrubs before they start new growth in spring.

Vegetable Garden Hacks by USDA Zone:

USDA Zones 3-5

  1. When: Late Fall (September-October)
    • Cold Frames & Row Covers: Set up cold frames or low tunnels over crops like spinach, carrots, or kale to extend the growing season into winter.
    • Mulching for Root Vegetables: Insulate root vegetables like parsnips and carrots with a thick layer of straw or leaves to prevent the soil from freezing.
    • Winter-Hardy Crops: Plant hardy crops like garlic, leeks, or winter spinach by late September to ensure they establish before the first hard frost.

USDA Zones 6-7

  1. When: Early Winter (November-December)
    • Cover Crops: Sow winter rye or hairy vetch as cover crops to protect and enrich the soil for spring planting.
    • Low Tunnels: Use low tunnels for crops like broccoli, spinach, and chard. They will continue to grow slowly under cover throughout winter.
    • Succession Planting: Plant winter crops like kale, carrots, and lettuce in October for harvest into early winter, and continue using row covers for protection.

USDA Zones 8-9

  1. When: Late Winter (December-February)
    • Winter Vegetables: Continue growing cool-season crops such as cabbage, peas, and onions without the need for heavy protection.
    • Frost Protection: In occasional frosts, use lightweight row covers to protect sensitive crops.
    • Mulching for Soil Health: Keep the soil covered with mulch, even in mild winters, to retain moisture and prevent weed growth.

Additional Winter Hacks for All Zones:

  1. Use Compost for Extra Heat (All Zones):
    • Build compost piles near garden beds to generate warmth from decomposing organic matter. This can raise temperatures around cold frames or perennial plants.
  2. Winter Greenhouses or Hoop Houses (Zones 3-7):
    • For zones with longer, harsher winters, consider using greenhouses or hoop houses to grow vegetables like spinach, lettuce, and herbs all winter long.
  3. Cloche Protection for Flowers and Veggies (All Zones):
    • Place cloches (glass or plastic domes) over smaller perennial flowers or winter vegetable crops to trap warmth, ideal for all USDA zones.

By focusing on zone-specific timing and protection methods, you can ensure your garden not only survives but thrives through the winter months.
