This article will reveal great information about the best plant companions for blueberries. I am growing multiple blueberry bushes in my garden.
The blueberry is a woody shrub. According to the Southern Appalachian Botanical Society, it belongs to the Vaccinium genus. it is a perennial highbush that grows for multiple years.
I have tried different plants to grow well along with them. Not all of the companion plants worked!
Select companion plants that grow in the same environment to strengthen your blueberry shrub. Do not choose plants competing with blueberry plants for space or resources.
For the blueberry plant, choose companion plants that like acidic soil with a soil pH of around 4.5. Choose plants that attract pollinators in the spring to help blueberries propagate.

Thyme belongs to the Lamiaceae family. This fragrant is native to the Mediterranean.

Growing two of the most delicious berries in the same garden makes sense for many reasons. Strawberry plants love acidic soil as blueberries. However, they prefer it just a bit more alkaline.
It’s fun to have different types of berries in your garden. But keep in mind that plants need a lot of nutrients and water to produce delicious fruit.
Separate strawberries and blueberries by at least a few feet. Ensure they are not competing for resources and space. Both of these plants require space.
Why Plant Strawberries with Blueberries
- Similar soil needs (acidic soil)
These beautiful flowers are a great match for blueberries. They bloom in the spring, like blueberries, attracting the same important pollinators.
Rhododendrons love the kind of acidic soil that blueberries thrive in, but they require a little more shade like on a porch.
If your garden includes pine trees, you might want to plant Rhododendrons underneath them to relieve them from direct sunlight.
Why Plant Rhododendrons with Blueberries
- Attract pollinators
- Acid-loving plants
Ferns provide more lush green to your garden and can grow well in the same kind of conditions as blueberries, albeit with a lot more shade.
Plant ferns underneath evergreen trees or shadowed areas, and reserve the sunniest spots for your blueberries.

If you have a small garden, you are probably not thinking about planting oak trees alongside your blueberry patch. However, these can support blueberry bushes if you have the room (or some pre-existing oak trees to plant around).
Blueberries and oak trees both like temperate climates and acidic soil. The root network that large oat trees establish retains water, providing more moisture for them to draw on, and falling leaves act as mulch and fertilizer.
Why Plant Oak Trees with Blueberries
- Also prefers temperate climates
- Retains water in the soil
- Provides mulch from falling leaves
13. Pine Trees
Blueberries can be a great understory crop for pine trees, which love the same kind of acidic soil and can help prevent pests. Falling pine needles can make a kind of protective mulch that inhibits weeds.
However, blueberries require a lot of light, so ensure they have enough space so they don’t get completely overshadowed.
Why Plant Pine Trees with Blueberries
- Love acidic soil

As an evergreen shrub, holly is a great addition to gardens in temperate climates. They flower during the winter when blueberries are dormant.
Holly benefits from acidic soil with plenty of moisture. Holly berries are toxic and inedible for both people and pets.

Peat, pine, bark sand, and peat moss are great soil additions. Fertilize monthly using an acid-forming fertilizer that blueberries like.
Rhododendron or Azalea mixes with an NPK of 20-10-20 are best. Blueberries are light feeders.
Plant blueberries in containers or in high ground. They are sensitive to frost, according to Tennessee State University.
Water until they are fully saturated.
