Companion Planting Raspberries and Blueberries

companion planting raspberries and blueberries

Companion planting is a gardening technique that involves planting two or more plants together for mutual benefit. Raspberries and blueberries are two fruits that can be grown together as companion plants, resulting in healthier plants and higher yields.

Why Companion Plant Raspberries and Blueberries?

Raspberries and blueberries are both members of the same plant family, Ericaceae. They have similar soil requirements and grow well in acidic soils with a pH between 4.5 and 5.5. Companion planting raspberries and blueberries can provide several benefits:

1. Pest Control

Pests can be a significant problem for berry crops, but by planting raspberries and blueberries together, you can confuse pests and prevent infestations. For example, planting garlic around the edge of your raspberry and blueberry bed can repel aphids, spider mites, and other pests that can damage your plants.

2. Improved Soil Quality

Raspberries and blueberries have shallow roots and need well-draining soil. By planting them together, you can improve soil quality and reduce erosion. Blueberries have a fibrous root system that helps hold soil in place. Meanwhile, raspberries have taproots that break up hard soil and improve nutrients' uptake.

3. Better Pollination

Pollinators, such as bees and butterflies, are essential for fruit production. By planting raspberries and blueberries together, you can attract more pollinators to your garden, resulting in better fruit set and higher yields.

Planting Raspberries and Blueberries Together

If you're interested in companion planting raspberries and blueberries, there are a few things you need to keep in mind:

1. Site Selection

Choose a sunny location with well-draining soil and good air circulation. Avoid planting raspberries and blueberries in low-lying areas prone to frost or waterlogging.

2. Soil Preparation

Raspberries and blueberries prefer acidic soils with a pH between 4.5 and 5.5. Test your soil and amend it with sulfur or peat moss if needed. Work in compost or well-rotted manure to improve soil quality.

3. Plant Spacing

Space your raspberries and blueberries at least 2 feet apart to allow for good air circulation and prevent disease spread. You can also plant them in rows with a 6-foot spacing between rows.

4. Mulching

Mulch your raspberry and blueberry bed with organic matter, such as straw or wood chips, to retain moisture and suppress weeds.

Caring for Your Raspberry and Blueberry Plants

To keep your raspberry and blueberry plants healthy and productive, follow these care tips:

1. Watering

Water your plants regularly, especially during dry spells. Avoid overwatering, as this can lead to root rot.

2. Fertilizing

Feed your plants with a slow-release fertilizer, such as compost or aged manure, in early spring and mid-summer.

3. Pruning

Prune your raspberry canes in late winter or early spring before new growth begins. Blueberries require minimal pruning but can benefit from some light pruning in late winter.

4. Pest Control

Monitor your plants regularly for pests and diseases. Remove any affected leaves or fruits promptly. Use natural pest control methods, such as companion planting and beneficial insects, to reduce the need for chemical pesticides.


Companion planting raspberries and blueberries can provide several benefits, such as improved soil quality, pest control, and better pollination. By following the tips outlined above, you can create a healthy and productive berry bed in your own backyard.
