How to Grow Potato in Arid / Semi-Arid Australia
- Soil
- Well-drained, loose, fertile loam enriched with compost. Slightly acidic soil reduces scab. Avoid waterlogged or compacted soil. Do not lime potato beds.
- Salt
- Moderately sensitive. Copes with a little salt, but the harvest drops on salty bore water.
- pH Range
- 5.5-6.5
- Sunlight
- Full sun (minimum 6 hours)
- Spacing
- 35cm apart, 70cm between rows
- Watering
- Consistent moisture is critical during tuber formation (flowering stage). Water deeply 2-3 times per week during dry periods. Reduce watering as foliage yellows and dies back.
- Good companions
- Nasturtium, Dwarf Beans, Sweet Corn, Basil, Marigold
- Keep away from
- Asparagus, Bitter Melon, Burdock, Capsicum (shares diseases), Cassava, Chickpeas, Cowpeas, Cucumber, Eggplant, Egyptian Spinach, Guava, Luffa, Peach, Pumpkin, Raspberry (share diseases), Rockmelon, Silverbeet, Summer squash, Sunflower (allelopathic inhibition), Tomato (shared diseases), Walnut (juglone sensitive), Watermelon, Zucchini

Harvesting Potato
When ready: Foliage yellows and dies back naturally. For 'new' potatoes, harvest when plants are flowering (about 10-12 weeks). For storage potatoes, wait 2-3 weeks after foliage has completely died to allow skins to set.
How to harvest: Use a garden fork inserted 30cm from the stem to avoid spearing tubers. Lift carefully and remove tubers by hand. Leave harvested potatoes on the soil surface for 1-2 hours to dry (no longer or they will green). Brush off soil but do not wash until ready to use.
Storing and preserving potato
How to keep it
- Cool Dark Storage. Cure freshly dug potatoes in a dark, well-ventilated area at 15-20C for 10-14 days to toughen skins. Then store at 4-8C in complete darkness. Paper bags, hessian sacks, or wooden crates with newspaper between layers. Never store in plastic. Check regularly for rot and remove affected tubers immediately. Keeps: 3-6 months depending on variety (some store 8+ months).
- Freezing. Peel and cut into chunks or mash. Blanch chunks for 4 minutes in boiling water. Ice bath, drain, freeze on trays then bag. Mashed potato freezes well with a knob of butter mixed in. Do not freeze raw potatoes. They turn dark and grainy. Keeps: 10-12 months.
- Dehydrating. Peel and slice thinly (3mm) or grate. Blanch 4-5 minutes. Pat dry. Dehydrate at 55-60C for 8-12 hours until brittle. Store in airtight jars. Rehydrate for soups, stews, or gratins. Keeps: 12 months in airtight containers.
- Canning (Pressure Canning Only). Potatoes are a LOW-ACID food and MUST be pressure canned. Water bath canning is NOT safe. Peel, cube, blanch 3 minutes. Pack into sterilised jars with hot water. Process at 10 PSI for 35 minutes (pints) or 40 minutes (quarts) in a pressure canner. Keeps: 12-18 months.
Canning safety. Low-acid vegetables like potato must be pressure canned, never water-bath canned.
