Companion Plants for Blueberries

Are you looking to create an impressive garden with blueberry bushes thriving in abundance? If so, one of the most important things that you need to consider is the companion plants for your blueberries. Knowing which companion plants are beneficial and which ones should be avoided can make all the difference when it comes to keeping your blueberries healthy and ensuring they reach their full potential. To help you get started, here is the ultimate guide to choosing the best companion plants for blueberries.

What Is Companion Planting?

Companion planting is the practice of intentionally pairing specific types of plants together in order to achieve a desired result. This could be for pest control, disease prevention, better soil nutrition, or improved pollination. By arranging your garden in this way, you can create an environment where all of the plants work together as a unit and benefit from each other’s company!

What Is Companion Planting?

When it comes to blueberries specifically, there are some great companion plants that can provide many benefits including increased yields and improved flavor. Let’s take a look at some of the top options!

Where to Plant Blueberry Bushes

Blueberry bushes prefer acidic soil and need full sun, so they’re best planted in an area with rich, well-draining soil that gets 8 hours or more of sunlight. If you have sandy, loamy soil, you can add organic matter to help retain moisture and make the soil more acidic. Blueberries can also be grown in containers, which makes it easy to move them around or give them the right light level if your garden is shady.

When planting blueberry bushes, remember to give them plenty of space — at least 3 feet apart for smaller varieties and 5-7 feet for larger ones — and use mulch after planting to keep weeds down and conserve moisture.
Avoid using chemical fertilizers as these can damage the roots of blueberries.

Companion Plants to Grow With Blueberries

Companion planting is a great way to get the most out of your blueberry bushes. Certain plants have been found to be beneficial companions for blueberries, helping with pollination, pest control, and even nutrient availability. Here are a few of our favorite companion plants for blueberries.


Basil is a great companion for blueberries, as it helps to repel pests and can also provide important nutrients. Basil contains an aromatic oil that deters some insects, while its strong scent may help disguise the smell of the blueberry bushes and attract beneficial insects like ladybugs. Additionally, basil can provide nitrogen and other essential nutrients to the soil around blueberry plants. Planting basil near your blueberry bushes will help keep them healthy and productive. When harvesting basil for cooking or other uses, be sure not to take too many leaves from any one plant so that all of your herbs remain productive!


Thyme is one of the best companions for blueberries and makes a great addition to any berry garden. Its strong scent helps repel many common pests, including whitefly, black vine weevil, and spider mites. The flowers also attract beneficial insects like hoverflies and lacewings that will help keep your blueberry crop healthy. Plus, it’s an attractive plant with small leaves and pretty pink or purple flowers that will add color to your garden. Plant thyme near your blueberry bushes in well-drained soil with plenty of compost added for nutrients. Water regularly and prune occasionally to encourage bushier growth. With its pest-repelling powers and lovely appearance, there’s no doubt thyme is a perfect companion for blueberries!


Parsley helps to repel harmful insects and improve the quality of the soil. Parsley also contains trace amounts of vitamins and minerals which can benefit your blueberry plants.


For best results, plant parsley near your blueberry bushes, but be sure to keep it away from any other vegetables or fruits in your garden as they may suffer from poor pollination. Additionally, try planting some deep rooted parsley varieties such as Giant Italian Parsley or Curled Leaf Parsley for maximum success with your blueberries!


Dill helps attract beneficial insects like hoverflies and parasitic wasps which help reduce harmful pests. In addition, dill grows quickly and can reach heights of up to three feet tall. Planting dill next to your blueberry bushes will also provide additional shade for the plants, helping keep them cool in hot weather. However, you should keep an eye out for any new growth that appears near your blueberry bush and make sure not to let the dill take over! Finally, if your soil is too alkaline for blueberries, adding a few sprigs of dill around the base of your plants could help balance out the pH level.


Borage is a popular companion plant for blueberries, as it encourages pollinator activity. Borage also adds nutrients to the soil and helps protect nearby plants from pests like aphids and caterpillars. It can be planted alongside your blueberry bushes in early spring, or you can sow seeds directly into the ground. Borage grows quickly and easily — just make sure not to overcrowd it too much, as this will reduce its effectiveness. To ensure optimal results, keep an eye on the flowering and growth of your borage plants throughout the season. If they become too tall or outcompete other plants in the area, consider trimming them back to give other surrounding vegetation room to grow. With proper care and attention, borage will bring beneficial insects to your blueberry patch, as well as help increase soil fertility and attract pollinators.


Strawberries help keep weeds away, improve pollination and add nitrogen to the soil, making them an ideal choice for blueberry gardeners. Planting strawberries around your blueberry bushes can also provide you with a tasty snack while you’re tending your plants!

When planting strawberries near your blueberries, it’s important to choose everbearing cultivars of strawberry rather than June-bearing varieties.
Everbearing varieties will frequently produce throughout the summer months and into late autumn, compared to June-bearing types which produce just once in mid-summer. Additionally, consider spacing your strawberry plants at least 18 inches away from the base of each blueberry bush so that their root systems don’t interfere with each other. By following these simple tips, you can have a delicious strawberry harvest alongside your blueberry harvest!


Pineberries are a relative of the blueberry family and make an excellent companion plant for a blueberry bush. Not only do they offer additional beauty to your garden, but their roots also help to protect the soil from erosion and add additional nutrients that can benefit both plants. Pineberries have white flowers with pink undertones and long, slender stems reaching up to two feet in height.


The berries themselves look like small strawberries but have a unique flavor that combines sweet pineapple with tart strawberry. Planting pineberries near your blueberries will create an interesting contrast as well as provide benefits to both plants. If you plan on harvesting your own pineberries, be sure to leave some in place so they can continue to cross-pollinate with the blueberries and help to keep them healthy.


Cranberries make an excellent companion for blueberries, as they share a number of beneficial characteristics. Firstly, cranberries are among the few plants able to tolerate acidic soil conditions and will therefore grow well in soils that are too low in pH for other plants. Secondly, cranberries help reduce problems with weeds as their dense foliage helps to keep them at bay. And lastly, cranberries help to improve the overall quality of the soil by adding valuable nitrogen into it through their roots. As an added bonus, when grown close together, blueberry and cranberry plants can even benefit from cross-pollination. So if you’re looking for a great companion plant for your blueberry patch, don’t forget about the humble cranberry!


Coneflowers, also known as echinacea, are a great companion plant for blueberries. These beautiful flowers will attract pollinators to your blueberry garden, helping to ensure successful fruiting and flowering. Coneflowers are easy to grow, coming in a variety of colors and sizes and requiring little maintenance once established. They do best in full sun and sandy soil with good drainage. To maximize the effectiveness of this companion plant, place them near your blueberry bushes but far enough away that they won’t become overrun by the roots of the larger plants. With their bright blooms and tough constitution, coneflowers can be relied upon to add beauty and provide beneficial pollination services for years to come!


The daisy flower is an important source of nectar for honeybees, and its roots help aerate the soil. Daisies also have a natural “weeding” effect since they release a toxin that helps prevent weeds from growing nearby them. Not only that, but they add beautiful pops of color to any garden! Plant these low-maintenance flowers in the same area as your blueberry bushes for an attractive and beneficial companion plant.


Azaleas and rhododendrons are excellent companion plants for blueberries. These lush, evergreen shrubs provide the perfect backdrop to any blueberry planting. Azaleas have beautiful, brightly-colored flowers that bloom in the spring, while rhododendrons have larger blooms that appear later in the season. As they’re both acid-loving plants, these two make great neighbors for your blueberries, and their long flowering period gives you plenty of eye-catching colors all through the summer months.


When planted together with your blueberry bushes, azaleas offer a low-maintenance way to create an attractive garden scene. Plus, because they’re evergreens, they can also provide shelter for your blueberry bushes in the winter.


Lilacs can help protect plants against pests such as aphids and mites. Planting them near blueberries also improves pollination, thus increasing berry yield. When choosing a variety of lilac to use for companion planting, opt for one with large flowers like Syringa vulgaris. To ensure optimal growth, make sure to provide your lilac with full sun and well-drained soil. Additionally, prune the shrub once a year in late winter or early spring to keep it healthy and encourage blooming. With proper care, these fragrant beauties will be an attractive addition to any landscape!


When considering companion plants for blueberries, it’s important to consider the Rhododendron family. These shrubs, which come in a variety of colors and sizes, provide dramatic color and texture for any garden. They prefer acidic soils and will thrive under the same conditions that are perfect for your blueberry bushes. Planting rhododendrons close by can also help keep away insect pests that may otherwise attack your berries. Choosing a low growing variety like ‘Raspberry Glow’ will add an interesting background for your blueberries without competing with them or blocking light from reaching the ground beneath them. Make sure you give these plants plenty of water as they have shallow root systems!

Trees and Shrubs that Grow Well with Blueberries

Trees and shrubs make great companions for blueberries. They can provide shade to protect the berries from scorching sunlight, as well as offer support for trellising or an espalier system. When selecting trees and shrubs to pair with your blueberry bushes, look for varieties that don’t require too much pruning or maintenance. Here are some suggestions.


Arborvitae is one of the best companion plants for blueberries. It is an evergreen shrub and provides year-round interest in the garden. Its dense foliage provides shade for blueberry bushes, helping to keep them cool during hot summer months.


The branches also help protect the berries from birds and other wildlife that may be attracted to their sweet taste. Arborvitae has been known to naturally repel deer, which can be a boon when growing blueberries in areas where deer are present. Additionally, it helps provide structure and texture to the landscape, making it visually pleasing as well as functional. Be aware that arborvitae can grow quite large over time so they should not be planted too close to your blueberries. Plant them at least five feet away from the bushes to ensure that they have plenty of room to grow without crowding your blueberry plants.

What should you not plant next to blueberries?

It is generally inadvisable to plant anything next to blueberries that belongs to the Brassicaceae family. This includes cabbage, broccoli, cauliflower, Brussels sprouts, kale and radishes. These plants tend to exude a chemical into the soil that interferes with the health of blueberry plants. Tomatoes should also not be planted near blueberries as they can introduce verticillium wilt into the area which is highly detrimental to blueberries. In addition, potatoes are susceptible to verticillium wilt so it’s also best not to plant them close by. Additionally, onions and garlic may stunt the growth of blueberries so these should also be kept away from blueberry patches. [2]

What is the best cover crop for blueberries?

Cover crops are great for protecting blueberry plants from weeds, soil erosion and leaching of vital nutrients. They also help increase the organic matter in the soil. Oats or winter rye is often considered to be the best cover crop for blueberries as they provide a good amount of nitrogen to the soil while suppressing weed growth. Another option is clover, which can reduce some weeds and it fixes nitrogen into the soil as well. Other cover crops such as wheat, barley and buckwheat can work too but may need more fertilizer to thrive. Make sure you use a pre-emergent herbicide before planting any cover crop to prevent the germination of weed seeds that might already be present in the soil.  Once your cover crop is established, you can mow it to keep the growth down or till it into the soil. However, you should avoid tilling in cover crops during the growing season as blueberries are sensitive to disturbance of their shallow root systems. [3]

What is the best planting mix for blueberries?

Blueberries grow best in loamy soil, rich in organic matter. The soil should be well drained and acidic, with a pH of 4.5 to 5.2. To ensure the soil is suitable for blueberry plants, add compost or other organic matter like peat moss to the planting mix when you prepare your garden bed. Additionally, adding sulfur can help lower the pH if it’s too high. You can also incorporate fertilizers which include phosphorus and potassium as this will give your blueberries an extra boost of nutrition! Finally, make sure that you are watering your plants regularly and evenly throughout their growing season; this will help keep them healthy and productive! [4]

What are the best blueberry bushes to cross pollinate?

Choosing the right blueberry bushes to cross pollinate is key for successful companion planting. Cross pollination produces better yields and bigger berries, so you’ll want to choose varieties that are compatible with one another.

Highbush blueberries are the most widely grown type of blueberry bush in North America, but there are other varieties such as rabbiteye, lowbush, and southern highbush blueberries. All of these types can be used for companion planting with some exceptions. For example, early-ripening varieties may not cross-pollinate well with late-ripening ones since they’re no longer flowering at the same time.

When choosing which plants to use for companion planting, look for a mix of early-ripening and late-ripening varieties to ensure the maximum amount of pollen is being exchanged. Some popular highbush varieties for cross pollination include:

  • ‘Bluecrop’ – a midseason variety that produces large, sweet fruit
  • ‘Berkeley’ – an early season variety with excellent flavor
  • ‘Elliott’ – a late season variety with firm berries
  • ‘Bluetta’ – an early season variety with great flavor and texture

Rabbiteye blueberries are also good for companion planting as they bloom at the same time as highbush varieties. Popular rabbiteye varieties include:

  • ‘Tiftblue’ – an early season variety with medium sized fruit
  • ‘Brightwell’ – a mid-season variety with large, sweet berries
  • ‘Premier’ – a late season variety with excellent flavor

You can also use lowbush or southern highbush varieties for cross pollination. Lowbush blueberries are smaller than the other types and tend to be more tolerant of cold temperatures. Popular lowbush varieties include:

  • ‘Brunswick’ – an early season variety that is easy to grow and produces good yields
  • ‘Northland’ – a late season variety with good flavor

Southern highbush blueberries are similar in size to highbush types but have lower chilling requirements, making them ideal for warmer climates. Popular southern highbush varieties include:

  • ‘Sharpblue’ – an early season variety with large, sweet berries
  • Sunshine Blue‘ – a mid-season variety that is cold tolerant and produces abundant yields
  • ‘Star’ – a late season variety with firm fruit and great flavor

By choosing the right blueberry bushes for cross pollination, you can ensure maximum yields from your companion planting efforts. Be sure to select both early-ripening and late-ripening varieties to get the best possible results. With the right combination of compatible plants, you’ll be rewarded with larger, sweeter berries!
