Capsicums are warm-season Solanaceae closely related to chillies, tomatoes and eggplant. They need a long, warm growing season to produce well. The coloured varieties (red, yellow, orange) are simply mature green capsicums left on the plant longer. A staple of Australian home gardens in warm and temperate zones.

Warm Temperate Growing Tips for Capsicum (Bell Pepper)

Recommended Varieties

  • California Wonder
  • Yolo Wonder
  • Sweet Banana
  • Marconi Red
  • Mini capsicums

Key Challenges

  • Slow start due to cool springs

  • Occasional fruit fly

Pro Tips

  • Start seeds indoors early (August) to maximise the growing season
  • Use wall-o-water or cloches for early transplants
  • Green capsicums are easiest. Coloured types need the longest season possible

Harvesting Capsicum (Bell Pepper)

When ready: Green capsicums: full-sized, firm, glossy skin. Coloured capsicums: leave on plant 2-3 weeks past green stage until fully coloured (red, yellow, orange depending on variety). Coloured fruit is sweeter with higher vitamin C.

How to harvest: Cut with sharp secateurs leaving a short stem. Do not pull. This damages the plant. Harvest in morning when firm and cool.
