Strawberries are one of Australia's favourite home garden fruits, producing sweet berries from compact plants that thrive in garden beds, pots, and hanging baskets. Understanding the difference between short-day, day-neutral, and everbearing types is critical for choosing the right variety for your zone. Plants produce via runners and need renovation every 2-3 years for best production.

How to Grow Strawberry in Tropical Australia
When to Plant
Plant runners March-May (start of dry season). Treat as annual - replace each year. Day-neutral types preferred for extended production.
- Soil
- Well-drained, slightly acidic soil enriched with compost. Sandy loam is ideal. Raised beds or mounded rows improve drainage. Strawberries hate waterlogged roots.
- pH Range
- 5.5-6.5
- Sunlight
- Full sun (minimum 6-8 hours). In tropical/subtropical zones, afternoon shade beneficial.
- Spacing
- 30cm apart, 75cm between rows
- Watering
- Regular consistent moisture during flowering and fruiting - 2-3cm per week. Drip irrigation or soaker hoses preferred. NEVER overhead water when fruit is developing - causes grey mould (Botrytis). Red
Companion plants: Borage (attracts pollinators, improves flavour - traditional companion), Lettuce, Spinach, Onion, Sage, Thyme
Avoid planting near: Brassicas, Fennel, Tomato, Capsicum

Harvesting Strawberry
When ready: Fully red/coloured all over (no white shoulders). Slight give when gently pressed. Fragrant strawberry aroma. Berries do NOT continue ripening after picking.
How to harvest: Pick in the morning when cool. Pinch stem 1cm above berry with thumbnail or use small scissors. Handle gently - strawberries bruise easily. Place in single layer in container. Refrigerate immediately or eat within hours.
