Dreaming of picking fresh, flavorful blueberries right in your backyard? Turn that dream into reality! Blueberry bushes offer delicious fruit, delicate spring blossoms, and striking autumn foliage. Follow our practical guide to select the best plants and succeed with in-ground or container planting.
Understanding the Two Main Types of Blueberries
Make an informed choice by identifying the two primary blueberry families grown in Canada:
- Lowbush Blueberries (Wild Blueberries): Extremely hardy, this native species (Vaccinium angustifolium) forms low-growing bushes (30 to 60 cm). It produces a bounty of sweet, intense berries in late summer.
- Highbush Blueberries: Taller in stature (1 to 1.8 m), this bush (Vaccinium corymbosum) yields large, juicy fruits starting in mid-July. Its height makes harvesting effortless.
Choosing the Right Cultivars for Maximum Yield
The Importance of Cross-Pollination
Boost your harvest! Even though some blueberry plants are self-fertile, plant at least two different cultivars from the same family close together. Cross-pollination dramatically increases both fruit size and yield through pollinator activity.

Hardiness Note: Always select cultivars suitable for your zone (zones 3, 4, or 5). In colder regions (zones 3 and 4), protect tender varieties like 'Peach Sorbet®' or grow them in containers to shelter them during winter.
Step-by-Step Blueberry Planting Guide
Plant in spring as soon as the risk of hard frost passes. Adapt your technique based on your available space.
Option 1: In-Ground Planting
Provide your plants with optimal growing conditions right from day one:
- Acidify the soil: Blueberries require highly acidic soil (pH 4.5 to 5.2). Dig a hole and blend equal parts of garden soil with acid-loving plant soil mix or sphagnum peat moss. Avoid adding household compost or regular manure, as their higher pH levels harm plant growth.
- Select the site: Pick a sunny location (minimum 6 to 8 hours of direct sun daily) sheltered from harsh winds.
- Dig a wide hole: Prepare a shallow yet wide hole (roughly 50 cm wide by 30 cm deep) to accommodate shallow root systems.
- Position the plant: Gently remove the container, tease out bound roots, and place the root ball. Never bury the root crown (where roots meet the stem) to prevent surface root rot.
- Backfill and water: Fill the hole with your acidic soil mixture, firm gently, and water thoroughly. Ideally, use rainwater for irrigation, as municipal tap water is often alkaline and gradually raises soil pH. Space highbush blueberries 1 to 1.5 metres apart.
Option 2: Container Gardening (Ideal for Balconies and Small Spaces)
Bypass soil limitations by growing blueberries in pots:
- Pick compact cultivars:
- 'Peach Sorbet®': Features stunning foliage and a compact habit perfect for containers.
- 'Northland': Offers outstanding cold hardiness (Zone 3) and high productivity.
- 'Polaris': A semi-dwarf variety that thrives effortlessly in tight spaces.
- Use a large pot: Choose a 40 to 50-litre container (such as a fabric Smart Pot) with drainage holes.
- Fill with acidifying potting mix: Use a specialized, ready-to-use acid-loving plant soil mix.
- Overwinter properly: In autumn, move the container to an unheated cool area (garage or shed) or wrap it with insulating fabric.
