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

Transplant September-October and February-March. Avoid midsummer extreme heat. The heat suits chillies but extreme temperatures above 40C cause flower drop.

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

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.
