What to Plant Near Blueberries: The Best Companion Plants for a Fruitful Harvest

Blueberries are a beloved fruit prized for their sweet-tart flavor nutrient density, and versatility. However, growing a flourishing and productive blueberry patch requires careful planning and an understanding of blueberry companion plants.

Selecting the right plants to cultivate alongside blueberries can enhance pollination improve soil conditions prevent pests, and boost yields. On the other hand, planting incompatible species nearby can hinder blueberry growth and health.

In this comprehensive guide, you’ll discover the best and worst companion plants for blueberries, along with helpful growing tips for a bountiful harvest.

An Overview of Blueberry Needs

Before delving into companion plant pairings, it’s crucial to understand the ideal growing conditions for blueberries:

• Soil: Blueberries require acidic soil with a pH between 4.5-5.0. This allows them to absorb nutrients effectively.

• Sun: At least 6 hours of direct sunlight daily. Morning sun is preferable to avoid sunscald.

• Water: Consistent moisture is key, especially during fruit set. But avoid soggy soil.

• Space: Blueberry bushes can spread 5-6 feet wide. Allow enough room for air circulation.

• Fertilizer: Use an acidic fertilizer formulated for blueberries. Avoid over-fertilizing.

With their preferences in mind, let’s explore the best companion plants to enhance blueberry growth.

7 Top Companion Plants for Blueberries

1. Azaleas

Azaleas thrive in acidic soil and provide dappled shade for blueberry bushes. Their bright blooms also attract pollinators. Space azaleas 2-3 feet away from blueberries.

2. Rhododendrons

Similar to azaleas, rhododendrons prefer acidic soil. Their large leaves offer protection from wind and sun. Place 2-3 feet apart.

3. Lingonberries

This low-growing perennial helps acidify soil and supplies ground cover to retain moisture. Plus, lingonberry flowers draw in pollinators. Allow 1-2 feet between plants.

4. Lily of the valley

The bell-shaped flowers of lily of the valley attract beneficial insects for pollination. Its spreading form makes an attractive ground cover. Keep 1 foot away from blueberry bushes.

5. Wintergreen

With its minty fragrance, wintergreen deters common blueberry pests like weevils. It also provides shade and fixes nitrogen. Allow 1-2 feet between plants.

6. Clovers

White and red clovers enrich the soil with nitrogen through their root nodules. Their low growth habit also suppresses weeds. Keep 1 foot between clover patches and blueberries.

7. Yarrow

With its naturally occurring compounds, yarrow repels aphids, mites, and other damaging pests. Its small flowers also draw in beneficial insects for pollination. Space 1-2 feet apart.

Companion Planting Tips

When interplanting blueberries, keep these tips in mind:

• Use taller companion plants on the north side to avoid shading blueberries.

• Scatter low-growing companions near bushes to cover and protect soil.

• Intersperse flowering plants to sustain pollinators throughout the season.

• Allow 2-3 feet between blueberry bushes and companion plants for sufficient airflow and light penetration.

• Test and amend soil regularly to maintain ideal acidity for blueberries.

What Not to Plant Near Blueberries

Some plants are unsuitable neighbors for blueberry bushes:

• Grasses: Aggressive grass roots compete for water and nutrients.

• Nightshades: Tomatoes, peppers, eggplants attract similar pests as blueberries.

• Legumes: Beans and peas prefer neutral soil instead of acidic.

• Brassicas: Cabbage, broccoli and Brussels sprouts thrive in less acidic soil.

• Alliums: Onions and garlic often stunt blueberry growth.

• Strawberries: These berries perform best in more neutral pH soil.

Keeping incompatible plants separate avoids unnecessary soil issues and pest problems.

Caring for Blueberries

Beyond smart companion planting, incorporate these practices for healthy bushes:

• Water: Supply 1-2 inches weekly. Drip irrigation works well.

• Mulch: Replenish pine bark or pine needle mulch yearly to retain moisture and acidify soil.

• Prune: Remove old stems in late winter to improve air flow and productivity.

• Netting: Protect ripening berries from birds with netting.

• Scouting: Check weekly for pests like mites, aphids, or beetles. Remove by hand or use insecticidal soap.

With the right companion plants, care, and patience, your blueberry patch will produce abundant, sweet berries for years to come. Let this guide help you craft a thriving and fruitful blueberry garden!
