Chillies are warm-season Solanaceae grown for their pungent fruit. Five cultivated species exist, with C. annuum (jalapeno, cayenne) and C. chinense (habanero, reaper) being most popular. They thrive in Australian heat and are easier to grow than capsicums because smaller fruit ripens faster. Perennial in frost-free areas.

How to Grow Chilli Peppers in Arid / Semi-Arid Australia

When to Plant

Chillies do well in pots that can be moved into shade in midsummer and under shelter from winter frost. Plant out after frost, with a second planting in January-February.

Soil
Well-drained, moderately fertile soil with compost. Slightly acidic preferred. Overly rich soil produces foliage over fruit.
pH Range
6.0-6.8
Sunlight
Full sun (minimum 6-8 hours). More sun = more heat in the fruit.
Spacing
45cm apart, 60cm between rows
Watering
Moderate and consistent watering. Slightly less water than capsicums. Some controlled water stress when fruit is ripening increases capsaicin (heat) levels. Avoid waterlogging.

Companion plants: Basil, Marigold, Tomato, Oregano

Avoid planting near: Fennel, Other Solanaceae in same rotation bed

Grow before, grow after

Chilli Peppers belong with the nightshades, the fruiting crops turn of a four turn bed rotation.

Grow before it
Leafy greens and brassicas (Lettuce, Silverbeet, Broccoli)
Grow after it
Roots and alliums (Carrot, Beetroot, Onion)

Give the bed 3 turns before nightshades go back in. Tomato, capsicum, eggplant and potato share wilts and blights that live on in the soil.

Arid / Semi-Arid Growing Tips for Chilli Peppers

Recommended Varieties

  • Cayenne
  • Jalapeno
  • Habanero
  • Bird's Eye
  • Anaheim

Key Challenges

  • Extreme heat above 40C causing flower drop
  • High water requirements

Pro Tips

  • Chillies love heat but even they have limits. Shade cloth above 40C
  • Arid conditions produce very hot chillies (water stress increases capsaicin)
  • Excellent climate for drying chillies naturally in the sun

Harvesting Chilli Peppers

When ready: Depends on variety and intended use. Green chillies: full-sized, firm, glossy. Ripe chillies: fully coloured (red, orange, yellow etc.). Hotter when fully ripe. Some varieties (jalapeno) can be used green or red.

How to harvest: Cut with scissors or secateurs leaving short stem. Do not pull. Wear gloves when harvesting super-hot varieties. Capsaicin on fingers causes painful burning if you touch eyes, nose or other sensitive areas.
