Blueberries are a delightful addition to any garden, offering delicious fruits and beautiful foliage. However, growing healthy blueberry bushes requires careful consideration of their companions. Companion planting can enhance growth, improve soil conditions, and even protect against pests.

In this blog post, we’ll explore the 15 best companion plants for blueberries and highlight some plants to avoid.

What is Blueberries?

Blueberries are small, round, blue or purple fruits that belong to the genus Vaccinium. They are native to North America and are widely known for their sweet and slightly tart flavor.

Blueberries are not only delicious but also packed with numerous health benefits. Let’s delve deeper into what blueberries are, their varieties, cultivation, and nutritional benefits.

Botanical Overview

Scientific Name: Vaccinium spp.

Family: Ericaceae

Common Varieties:

  • Highbush Blueberries (Vaccinium corymbosum): These are the most common type found in grocery stores and are known for their larger size and juiciness. They thrive in temperate climates.
  • Lowbush Blueberries (Vaccinium angustifolium): Also known as wild blueberries, these are smaller, have a more intense flavor, and are often used in processed foods like jams and baked goods.
  • Rabbiteye Blueberries (Vaccinium virgatum): Native to the southeastern United States, these are heat-tolerant and can grow in less acidic soils compared to highbush and lowbush varieties.


Blueberries are perennial flowering plants that can thrive for many years with proper care. They require specific growing conditions to produce abundant and healthy fruits.

Soil Requirements:

  • Acidic Soil: Blueberries prefer acidic soil with a pH between 4.5 and 5.5. Soil pH can be adjusted using sulfur or other acidifying agents if necessary.
  • Well-Drained Soil: They require well-drained soil to prevent root rot. Raised beds or mounded rows can help ensure proper drainage.

  • Blueberries thrive in regions with cold winters, which provide the chilling hours needed for the plants to produce fruit.
  • Highbush blueberries are suitable for USDA hardiness zones 3 to 7, while rabbiteye blueberries are more heat-tolerant and can grow in zones 7 to 9.


  • Full sun is ideal for blueberry plants, requiring at least six to eight hours of direct sunlight daily.


  • Blueberries have shallow root systems and need consistent moisture. However, they do not tolerate waterlogged conditions. Drip irrigation or soaker hoses are effective methods to provide adequate water.


  • Regular pruning helps maintain plant health and improve fruit production. Remove dead or weak branches and thin out older canes to encourage new growth.
