Blueberry Care Guide for BC 

How to Plant, Grow & Harvest Blueberries 

Blueberries (Vaccinium species) are one of the easiest and most rewarding edible shrubs for British Columbia gardens. These attractive plants produce delicious berries while also offering beautiful spring flowers and vibrant fall foliage. 

Blueberries thrive in acidic soil with consistent moisture and perform exceptionally well in many parts of British Columbia. 

 

Choosing the Right Blueberry Type 

Blueberries are grouped by their harvest season and plant size. 

Early Season Blueberries 

• Fruit ripens early in summer 

• Often the first berries ready to harvest 

Examples include: 

• ‘Duke’ 

• ‘Patriot’ 

 

Mid-Season Blueberries 

• Fruit ripens mid-summer 

• Reliable yields and excellent flavour 

Examples include: 

• ‘Bluecrop’ 

• ‘Toro’ 

 

Late Season Blueberries 

• Extend the harvest season into late summer 

Examples include: 

• ‘Elliott’ 

• ‘Aurora’ 

Planting a mix of early, mid, and late varieties helps ensure a continuous harvest throughout the summer. 

 

Pollination & Fruit Production 

Blueberries are self-fertile but produce larger crops and better fruit set when multiple varieties are planted nearby. 

Benefits of planting more than one variety: 

• Improved pollination 

• Larger berry size 

• Higher yields 

• Extended harvest season 

Bees are important pollinators for blueberries and help improve fruit production. 

 

How to Plant Blueberries 

Blueberries have very specific soil needs, and proper preparation is key to success. 

Sun Requirements 

• Full sun is ideal 

• Minimum 6 hours of sunlight daily 

• Some afternoon shade may help protect plants in hotter inland gardens 

 

Soil Requirements 

Blueberries require strongly acidic soil. 

Ideal conditions: 

• Soil pH between 4.5–5.5 

• Rich organic matter 

• Excellent drainage 

Amend soil with: 

• Compost – we recommend Sea Soil, Gardenworks Composted Mushroom Manure or Gardenworks Composted Cattle Manure  

• Bark mulch 

• Acidic soil amendments such as soil acidifier if necessary 

 

Planting Steps 

1. Dig a hole twice as wide as the root ball.   

2. Amend soil with compost and organic matter. 

3. Plant at the same depth as the plant growing in its container. 

4. Water thoroughly with Gardenworks Transplanting Fertilizer 5-15-5 to encourage root development. 

5. Apply 2–3 inches (5-7cm) of mulch (bark mulch works well). 

Mulch helps maintain soil acidity and retain soil moisture. 

 

Watering Blueberries 

Blueberries require consistent moisture. 

• Water regularly during the growing season 

• Avoid allowing soil to dry completely 

• Deep watering during hot, dry summer periods helps maintain fruit quality 

Mulch helps reduce moisture loss and protects the plant’s shallow root system. 

 

Fertilizing Blueberries 

Blueberries are light feeders but benefit from proper nutrition. 

• Fertilize with Gardenworks Fruit Tree & Berry Food 4-20-20 

• Apply in early spring 

• Avoid heavy fertilization 

Compost top-dressing in spring or fall also improves soil health. 

 

Pruning Blueberries 

Pruning helps maintain productivity and plant health. 

• Begin pruning after plants are 2–3 years old 

• Remove dead or weak branches 

• Thin older wood to encourage new growth 

• Maintain open structure for good sunlight penetration and airflow. 

Prune during late winter while plants are dormant. 

 

Growing Blueberries in South Coastal BC 

Blueberries grow exceptionally well in coastal BC. 

Climate Advantages 

• Mild winters 

• Moderate summer temperatures 

• Naturally acidic soils in most areas 

These conditions closely match the plant’s natural growing environment. 

 

Coastal Considerations 

• Improve drainage in heavy clay soils 

• Protect fruit from birds with netting 

• Maintain mulch to support soil acidity 

Blueberries are widely grown both commercially and in home gardens throughout coastal BC. 

 

Growing Blueberries in Penticton & the Okanagan 

Blueberries can grow inland but require more soil preparation. 

Climate Challenges 

• Hot, dry summers 

• Alkaline soils are common 

• Greater temperature swings 

 

Inland Care Adjustments 

• Amend soil heavily to increase acidity with soil acidifier fertilizer  

• Use raised beds if soil pH is high 

• Provide consistent irrigation 

• Mulch heavily to protect the plant’s shallow roots 

Careful soil preparation and ongoing soil management is the key to success inland. 

 

Common Blueberry Problems & Solutions 

 

Yellow Leaves 

Possible causes: 

• Soil too alkaline 

• Poor drainage 

• Nutrient deficiency 

Solutions: 

• Maintain acidic soil conditions 

• Apply fertilizer designed for acid-loving plants 

• Improve soil with organic matter 

 

Small or Few Berries 

Possible causes: 

• Lack of pollination 

• Insufficient sunlight 

• Poor pruning 

Solutions: 

• Plant multiple varieties 

• Ensure full sun exposure 

• Prune regularly to encourage new fruiting wood 

 

Birds Eating Fruit 

Birds are one of the most common blueberry pests. 

Solutions: 

• Use bird netting during fruit ripening 

• Harvest berries regularly as they ripen 

 

Poor Plant Growth 

Possible causes: 

• Incorrect soil pH 

• Compacted soil 

• Lack of organic matter 

Solutions: 

• Test soil pH 

• Improve soil with compost and mulch to increase organic matter
