Turnips are a fast-growing, cool-season root crop that matures in 6-10 weeks. Both the root and the nutritious leafy tops (turnip greens) are edible. They are easier and faster than swedes, making them a better choice for warmer Australian zones where swedes struggle. An underrated vegetable that deserves a place in every winter garden.

How to Grow Turnip in Cool Temperate Australia

When to Plant

Plant August-April. Almost year-round in Melbourne. Best from February-April (autumn) and August-October (spring).

Soil
Well-drained, fertile loam with good moisture retention. Avoid heavy clay or compacted soil which causes misshapen roots. Prepare with well-rotted compost.
pH Range
6.0-7.5
Sunlight
Full sun to light shade
Spacing
12cm apart, 30cm between rows
Watering
Consistent, even moisture is critical. Irregular watering produces woody, pithy, bitter roots. Water deeply 2-3 times per week in dry conditions.

Companion plants: Pea, Onion, Garlic, Nasturtium (trap crop for aphids)

Harvesting Turnip
