Companion Plants for Strawberries: A Comprehensive Gardening Guide

Companion Plants for Strawberries: A Comprehensive Gardening Guide

Strawberries are a favorite among gardeners for their sweet flavor, ease of cultivation, and vibrant presence in any garden setting. However, to ensure a strong harvest and healthy plants, it’s essential to give some thought to what’s growing nearby. Certain plants can offer strawberries critical support in the form of pest control, improved soil structure, and better pollination. This practice is known as companion planting.

In this guide, you'll discover which companion plants are most beneficial for strawberries and which ones to avoid, along with strategies for planting layouts and seasonal planning to get the most out of your strawberry patch.


Understanding the Role of Companion Plants

The idea behind companion planting is based on the natural relationships between various plant species. When chosen wisely, neighboring plants can enhance each other’s growth, reduce pest populations, and make better use of garden space. For strawberries, the benefits of companion planting are especially significant.

Benefits of Companion Planting for Strawberries:

  • Enhanced pest control: Some plants naturally repel insects that commonly affect strawberries.

  • Boosted pollination: Flowering companions can attract bees and other pollinators, leading to higher fruit yields.

  • Soil improvement: Certain species improve the soil by fixing nitrogen or adding organic matter.

  • Microclimate management: Ground cover and shade from other plants can help strawberries conserve moisture.

Let’s look at some of the best companion plants for strawberries and why they work so well.


Top Companion Plants for Strawberries

Borage

Borage is widely recognized for its compatibility with strawberries. This flowering herb not only draws bees to the area, increasing pollination rates, but it’s also believed to enhance the flavor and health of strawberry plants.

Advantages:

  • Attracts pollinators like bees and beneficial insects

  • Improves strawberry taste

  • Acts as a green manure when tilled into the soil

Placement Tips: Position borage around or between strawberry rows. Its height and flowers provide a striking visual contrast while benefiting the crop.


Lettuce

Lettuce is a fast-growing crop that coexists well with strawberries. It offers ground cover that helps control weeds and maintain soil moisture.

Advantages:

  • Quick to grow and harvest

  • Competes minimally for nutrients

  • Helps prevent soil from drying out

Planting Strategy: Sow lettuce seeds between strawberry plants early in the season. As strawberries mature, lettuce will be ready for harvest, freeing up space.


Spinach

Spinach provides another great companion option for strawberries. It matures rapidly and requires little maintenance, allowing for dual-purpose gardening in shared plots.

Advantages:

  • Suppresses weeds

  • Doesn’t crowd strawberry roots

  • Efficient use of space

Planting Strategy: Plant in the same raised bed or plot as strawberries in spring. Remove after harvest and allow strawberries to spread into the cleared area.


Garlic and Onions

These alliums release a strong scent that masks the smell of strawberries, making it harder for pests to find the fruit. They’re particularly effective against aphids, spider mites, and even rabbits.

Advantages:

  • Repels pests naturally

  • Easy to grow alongside strawberries

  • Low-growing, so they don’t block sunlight

Planting Strategy: Border your strawberry beds with garlic or onions. Leave several inches between them and the berries to avoid crowding.


Chives

Chives share many of the same pest-deterrent properties as garlic and onions. They also add a beautiful burst of purple when in bloom, bringing in pollinators.

Advantages:

  • Aphid deterrent

  • Adds color and visual appeal

  • Minimal maintenance required

Planting Strategy: Use chives as edging around strawberry beds or plant in pots placed nearby.


Thyme

Thyme grows close to the ground, making it an effective living mulch. Its strong aroma also helps deter insects like cabbage worms and whiteflies.

Advantages:

  • Provides low-maintenance ground cover

  • Deters various garden pests

  • Aromatic and edible

Planting Strategy: Grow thyme in clusters between strawberry plants or use it as a border herb around your patch.


Marigolds

Marigolds are widely used in gardens to prevent nematode infestations. Their scent also keeps beetles and other pests at bay. Their vibrant color is an added benefit.

Advantages:

  • Repels nematodes and beetles

  • Attracts pollinators

  • Adds ornamental value

Planting Strategy: Scatter marigolds throughout the strawberry bed or plant them at row ends for visual and functional balance.


Beans and Peas

As nitrogen fixers, legumes like beans and peas can enrich the soil naturally. Strawberries don’t need heavy nitrogen, but a mild enrichment can still be beneficial when managed properly.

Advantages:

  • Improve soil health

  • Don’t compete for root space

  • Support diverse garden ecosystems

Planting Strategy: Grow bush varieties near strawberries or install a trellis for pole beans slightly away from the berry beds to avoid shading.


Carrots

Carrots grow vertically underground, which minimizes competition with strawberries for nutrients. Their presence can even improve soil texture.

Advantages:

  • Efficient vertical growing habits

  • Break up compacted soil

  • Easy to harvest alongside strawberries

Planting Strategy: Alternate rows of strawberries and carrots in raised beds for optimal space use.


Plants to Avoid Near Strawberries

Just as some plants are helpful companions, others can hinder your strawberry crop due to competition, shared diseases, or disruptive growth patterns.

Brassicas (Cabbage, Broccoli, Cauliflower)

These heavy feeders compete aggressively for soil nutrients and can stunt the growth of strawberries. Additionally, they may attract pests that affect both types of plants.

Tomatoes

Tomatoes are prone to diseases like verticillium wilt, which also affect strawberries. Their tall growth can block sunlight from reaching low-growing berries.

Eggplants and Peppers

These relatives of tomatoes carry similar disease risks and also compete for space and nutrients.

Melons and Squash

Their sprawling vines can overshadow strawberries and make harvesting difficult. They also consume large amounts of water and nutrients.

Mint (when uncontained)

While mint can deter pests, it spreads rapidly and can quickly overtake a strawberry patch unless kept in containers.


Garden Layout Suggestions

Raised Beds

  • Center: Strawberry plants

  • Border: Thyme, garlic, or chives

  • Between rows: Lettuce or spinach

  • Corners: Marigolds or borage

Container Gardens

  • Main container: Strawberries

  • Small nearby pots: Mint (in containers), basil, or chives

  • Vertical trellis nearby: Pole beans for nitrogen-fixing support

Traditional Rows

  • Alternate rows of strawberries and carrots or lettuce

  • Interplant with herbs like thyme and garlic

  • Edge the garden with marigolds for a natural pest barrier


Seasonal Companion Planting Strategy

By rotating plants throughout the year, you can keep your soil healthy and your strawberries thriving.

  • Spring: Start with spinach, lettuce, and radishes alongside strawberries.

  • Summer: Swap out early crops for herbs and beans.

  • Fall: Introduce garlic and onion sets to overwinter and support next season’s growth.


Natural Pest Control with Companion Plants

Companion planting can help reduce or eliminate the need for chemical pesticides. Plants like chives, garlic, and marigolds deter common threats such as:

  • Aphids

  • Slugs

  • Japanese beetles

  • Spider mites

Additionally, flowering companions attract helpful predators like:

  • Ladybugs

  • Hoverflies

  • Lacewings

These insects feed on harmful bugs and maintain a balanced garden ecosystem.


Mulching and Soil Health Using Companions

Some companion plants can serve a dual purpose by acting as mulch. When trimmed and placed around strawberries, they can:

  • Suppress weeds

  • Retain soil moisture

  • Decompose into organic fertilizer

Thyme, lettuce, and spinach are especially effective when cut back and used in this way.


Final Thoughts

Companion planting is a valuable approach for gardeners seeking to grow healthy, productive strawberry plants. Whether you're working with a small raised bed, an expansive traditional garden, or a set of containers on a balcony, choosing the right companions can dramatically influence the success of your strawberry crop.

From pest control and pollination to soil enrichment and space management, these partner plants serve multiple functions that support strawberries throughout the growing season. With careful planning and thoughtful placement, your strawberry garden can thrive naturally—full of color, aroma, flavor, and life.
