What is Companion Planting?

What is Companion Planting
You can strategically plant certain veggies and flowers together to boost growth, deter pests, and attract pollinators.

One great example for your fall garden is pairing radishes and carrots. These quick-growing root veggies happily share space. The radishes emerge first while the carrots are still small. They protect carrots from pests and weeds as companions.

You can also interplant flowers like marigolds or calendula. Their bright blooms attract ladybugs, lacewings, and other beneficial insects.

Research shows specific plant partners really do help each other thrive. Apply this natural synergy through thoughtful companion planting in your fall garden.

Benefits of Companion Planting

Benefits of Companion Planting
Let’s take advantage of nature’s synergies. Companion planting optimizes your vegetable garden with strategic plant pairings for pest control, pollination aid, and growth enhancement. Certain plants deter specific pests, others attract pollinators, while compatible neighbors enhance each other’s growth and flavor through positive biological interactions.

Pest Control

Here are some tips about terrific tandem plantings that thwart bothersome bugs. Pluck pesky aphids, shield succulents from slugs, ward off whiteflies, apprehend asparagus beetles by interplanting allies like garlic, mint, onions, and flowers.

These savvy selections lure helpful critters like ladybugs that munch on menaces.

Pollination Aid

Certain flowers attract beneficial insects that pollinate crops when companion planted. Draw in pollinators like bees, wasps, butterflies, and hummingbirds with bright blossoms such as marigolds, zinnias, cosmos, and sunflowers.

Strategically place them near plants that need insect pollination, such as squash, melons, cucumbers, and beans. You’ll increase visits from pollinators and boost fruit set for better harvests.

Growth Enhancement

Carefully choosing plant companions can boost your harvest. Let’s get creative and try new combinations that benefit soil health, provide natural pest solutions, and attract pollinators. Certain flowers and herbs actually enhance growth and yields of vegetables when planted nearby.

For example, aromatic herbs like basil and parsley can significantly increase tomato yields and flavors. Planting bee-friendly blooms among brassicas can increase pollination and fruit set. Even specific combinations like onions and carrots or beans and corn can positively impact each other’s growth and productivity.

Maximizing these natural partnerships through companion planting leads to healthier, more productive vegetable gardens.

Examples of Successful Companion Plant Pairs

Examples of Successful Companion Plant Pairs
When designing your fall vegetable garden, research companion planting pairs to boost growth and deter pests. Classic companions like tomato-basil, garlic-onions, and mint-cabbage enhance flavor and growth while repelling insects.

Strategic companions like nasturtiums-brassicas, parsley-tomatoes, sage-carrots, and sunflowers-beans/cucumbers lure beneficials that control pests. Don’t forget to add flowers like calendula and cosmos that attract predatory wasps to keep destructive aphids in check.

With the right companion plant pairings, you’ll boost your fall harvest while minimizing pest damage.

Tomato and Basil

Grow basil among your tomatoes and enjoy tastier produce! This aromatic, flavorful pairing drives away pests like aphids while attracting beneficial pollinators.

Tomato Basil Benefits
Full sun Partial shade Pest protection
Fertile, well-drained soil Moist, nutrient-rich soil Tastier tomatoes
Consistent moisture Tolerates drought Prolonged harvest

When planted together, tomatoes and basil make for pungent pest protection, beneficial bug attraction, and delicious flavorful pairings.

Garlic and Onions

Surround your onions with garlic to deter pests from the entire garden. Interplanting garlic near onions boosts beneficial insects while deterring aphids, onion flies, and beetles. The pungent scent of garlic confuses pests, masking vulnerable alliums. Garlic’s antifungal properties also promote soil health for robust onion family growth.

Let garlic’s strong aroma permeate your garden, enhancing growth and deterring pests.

Mint and Cabbage

Plant mint around your cabbage to deter pests while containing it in a pot to prevent invasiveness.

  • Mix mint with radishes and peas to boost cabbages naturally.
  • Curb bugs like aphids by letting mint leaves brush cabbages.
  • Deter pests and grow flawless produce without chemicals.
  • Keep mint restrained to avoid it crowding out carrots and other crops.
  • Let mint’s aroma permeate garden beds for pest control and great flavor.

Growing mint with cabbage helps maximize your garden’s efficiency and productivity.

Nasturtiums and Brassicas

Try our nasturtiums next to brassicas – research shows they lure up to 60% more pests away. Attract 35% more beneficials by pairing nasturtiums and brassicas, as the bugs avoid brassicas yet adore nasturtiums’ leafy greens.

This companion planting deters pests like aphids with plant diversity while enticing ladybugs and hoverflies that gobble them up. Nasturtiums charm the pests away from your broccoli and kale so they thrive pest-free.

Parsley and Tomatoes

Mix parsley among your tomatoes to attract beneficial insects for natural pest control. Parsley is a smart choice to nourish the soil near tomatoes. Its delicate foliage shelters ground-nesting predatory wasps while inviting hoverflies that devour crop-damaging aphids.

Just a few parsley plants will attract pollinators and predators to your plot for higher yields.

Sage and Carrots

You’ll ward off those pesky carrot flies if you grow some sage alongside your carrots, as the old folks say. The aromatic oils of sage deter the egg-laying carrot maggots. Plus, sage enhances the flavor of carrots when planted nearby.

  • Repels carrot maggots
  • Deters cabbage moths
  • Attracts beneficial insects
  • Enriches carrot flavor
  • Controls pests naturally

Sunflowers and Beans/Cucumbers

Plant towering sunflowers amidst vining beans and cucumbers, and their broad leaves and sturdy stalks will support the weaker climbers.

Sunflowers Beans & Cucumbers
Provide support Climb & sprawl
Shade soil Access sunlight
Attract pollinators Produce fruit

Integrating sunflowers boosts vines, staking sprawling crops, and shading soil while attracting pollinators to encourage abundant bean and cucumber growth.

Tansy and Cutworms

Attract the ladybug’s little helpers around your plants while banishing the cutworm’s chewing jaws. Grow aromatic tansy near tomatoes, cabbage, kale, and broccoli to draw in beneficial insects that prey on cutworms.

Tansy’s pungent scent masks vulnerable seedlings while repelling the night feeders. Interplant with marigolds for extra cutworm protection. Check under mulch for curled caterpillars to handpick.

Calendula/Cosmos and Aphids

More flowers like calendula and cosmos attract tiny wasps that prey on aphids, so you gotta interplant them near veggies susceptible to aphid damage. They lure hoverflies, ladybugs, and other beneficials to control cabbage aphids on kale, broccoli, lettuce, and beans.

Marigolds make great partners to draw pollinators and predators, protecting companion plants naturally.

Pair peas with carrots or mint for mutual benefits in your patch. Growing peas with hardy root veggies or fragrant herbs has its advantages.

  • Sow pea and radish seeds together in a bed for a tried-and-tested way to boost nitrogen.
  • Use trellises so pea vines don’t smother carrot tops or mint beds as they grow tall.
  • Pick peas regularly once pods plump up to keep plants producing; harvest radishes promptly before they bolt.


Snip a few sprigs of thyme near your carrots to help prevent the dreaded carrot fly.

Herb Companion Plant Pairings

Tuck marigolds between your tomatoes for natural pest control. Their bright blooms attract butterflies, while the strong scent deters caterpillars that can ravage tomato plants. Mass plant marigolds along vulnerable crops like broccoli or beans. Use interplanting tips, like pairing them with oregano and rosemary too, for a blended insect repellent.

Perfect Pairs

Place Tuscan kale and Swiss chard side by side so the leafy greens can deter cabbage worms from one another. Grow radishes alongside your corn to pull double duty, attracting beneficial insects and improving airflow and soil structure for bigger yields.

Interplant pole beans and peas to climb the vines, forming a living trellis and deterring spider mites. Mind the planting arrangements between friends and foes to boost wildlife habitats.
