Acid-loving shrub that MUST have acidic soil (pH 4.5-5.5). Most Australian soils are too alkaline. Growing in pots with specialist acidic potting mix is the most reliable approach for most home gardeners. Three main types: northern highbush (high chill, cool climates), southern highbush (low chill, warm climates), and rabbiteye (tough, heat-tolerant, moderate chill). Grafted plants on rabbiteye rootstock now available for improved performance.
How to Grow Blueberry in Arid / Semi-Arid Australia
When to Plant
Grow in pots only. Plant autumn.
- Soil
- ACIDIC soil, pH 4.5-5.5. This is non-negotiable. Use 50:50 peat moss and pine bark for pots. In-ground only in naturally acidic soils (rare in Australia). Add sulphur to lower pH - takes 3-6 months to work.
- pH Range
- 4.5-5.5 (CRITICAL - will not thrive outside this range)
- Sunlight
- Full sun to part shade. Morning sun with afternoon shade ideal in hot zones. At least 6 hours direct sun for best fruiting.
Companion plants: Azalea, Rhododendron, Strawberry (woodland types)
Avoid planting near: Lime-loving plants, Concrete paths (leach alkalinity into soil)

How to harvest: Pick by hand, rolling berries gently off cluster. Harvest every 2-3 days as berries ripen unevenly. Early morning harvest for best quality.
