A single chilli plant left to ripen fully can produce far more heat, and far more fruit, than most people expect from one pot.
Chillies and peppers need a long, warm growing season, so they’re typically the earliest seeds sown of the year, often on a heat mat to germinate reliably. Fruit left to ripen fully to red (rather than picked green) develops more heat and sweetness.

Care details
- Sow January – February
Sow early on a heat mat — they need a long growing season.
- Plant May – June
Plant out or move outside once nights are reliably warm.
- Harvest July – October
Pick regularly; leave some to ripen red for extra heat and sweetness.
Growing tips & common problems
- Feed with a high-potash tomato feed once flowering starts, to support fruit rather than leafy growth.
- Mist occasionally or tap flowers gently to help pollination indoors, where there's no wind or insects to do it.
- Let fruit ripen fully to red or yellow rather than picking green, if heat and flavour matter more than yield.
