Potatoes are Australia's most important vegetable crop and one of the most rewarding to grow at home. They are grown from certified seed potatoes (not true seed), produce generous yields in most climates, and store well. Planting times vary dramatically by zone, with subtropical growers planting in autumn/winter and temperate growers in spring.

  • Coliban
  • Desiree
  • Pontiac

Key Challenges

  • Extreme summer heat prevents tuberisation

  • Potato moth in warm conditions

Pro Tips

  • Two potential planting windows: autumn and early spring
  • Drip irrigation under heavy mulch is the best approach
  • Test and acidify soil if pH is above 6.0 to prevent scab

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.
