How to Grow Beetroot in Subtropical Australia
- Soil
- Well-drained, loose loam or sandy loam enriched with compost. Avoid heavy clay unless amended. Do NOT add fresh manure. It causes forked, hairy roots.
- Salt
- Moderately tolerant. Handles slightly salty water better than most veggies.
- pH Range
- 6.0-7.5
- Sunlight
- Full sun (6+ hours). Tolerates light afternoon shade in hot climates.
- Spacing
- 10cm apart, 30cm between rows
- Watering
- Consistent moisture is critical. Irregular watering causes woody, cracked roots. Water deeply 2-3 times per week. Drip irrigation or soaker hose preferred. Overhead watering in humid zones promotes cercospora leaf spot.
- Good companions
- Dwarf Beans, Lettuce, Onion, Dill, Garlic
- Keep away from
- Climbing Beans, Quinoa, Spinach (same family; shared pests and diseases)
- Grow before it
- Fruiting crops (Tomato, Capsicum, Zucchini)
- Grow after it
- Legumes (Beans - Dwarf, Peas, Broad Beans)
Give the bed 3 turns before root crops go back in. Roots fork and go leafy in fresh manure, so they take the bed after the heavy feeders have used it.

Harvesting Beetroot
When ready: Roots visible at soil surface, typically 5-8cm diameter. Shoulders push above soil line. Leaves still green and vigorous. Baby beets can be harvested from 4 weeks at 3-4cm diameter.

Storing and preserving beetroot
How to keep it
- Lacto-Fermentation (Kvass/Fermented Beet). Peel and dice raw beetroot into 1-2cm cubes. Pack into clean glass jar. Prepare 3% brine (30g salt per litre of filtered water). Pour brine over beets, ensuring all pieces are submerged (use a fermentation weight). Loose lid. Ferment at room temperature (18-24C) for 5-7 days. Taste daily after day 3 - should be tangy and slightly effervescent. Seal and refrigerate. Keeps: 3-6 months refrigerated.
- Freezing. Cook whole beets until just tender. Cool, peel, and slice or dice. Spread on tray in single layer, freeze until solid (2 hours), then transfer to freezer bags removing air. Label with date. Keeps: 12 months frozen.
- Dehydrating. Cook beets until just tender. Peel and slice thinly (3mm). Arrange on dehydrator trays without overlapping. Dehydrate at 55-60C for 8-12 hours until crisp. Beetroot chips are a great snack. Keeps: 6-12 months in airtight container.
- Root Cellar / Cool Storage. Twist off tops (do not cut). Do not wash. Layer in boxes of damp sand or sawdust in a cool (1-4C), dark, humid place. Check monthly for soft spots. Keeps: 3-5 months.
- Pickling (Classic Australian Beetroot). Boil or roast whole beets (do not peel first) until tender (40-60 minutes depending on size). Cool, slip skins off, slice into rounds or wedges. Pack into sterilised jars. Prepare pickling liquid: 2 cups white vinegar, 1 cup sugar, 1 tsp salt, 6 whole cloves, 6 peppercorns. Boil liquid, pour over beets to 1cm from rim. Seal with new lids. Water bath process for 30 minutes. Keeps: 12 months (sealed jar, cool dark place). Refrigerate after opening..
Canning safety. Low-acid vegetables like beetroot must be pressure canned, never water-bath canned.
