Containers and small spaces
- Grow one plant per 10 to 20 litre pot on a sunny patio.
- Use self-watering containers to stop wilting in heat.
- Line a balcony rail with compact varieties like Thai or Apache.
- Grow peppers in grow bags against a warm wall.
- Bring a pot indoors to a sunny windowsill for winter.
Companions and care
- Pair peppers with basil to fill gaps and attract pollinators.
- Underplant with marigolds to bring in beneficial insects.
- Mulch with straw to keep roots evenly moist.
- Stake taller plants before fruit gets heavy.
- Feed with a high-potash tomato feed once flowers appear.
Harvest and beyond
- Plant a hot sauce row of cayenne, Fresno and habanero.
- Hang a drying rack or ristra of picked chillies.
- Save seed from open-pollinated favourites.
- Overwinter plants by pruning and keeping them frost-free.
- Pick regularly to keep plants flowering and fruiting.
Tip: Wear gloves when picking, cutting or deseeding hot peppers, never touch your eyes or face until you have washed your hands well, label very hot varieties clearly, and keep extreme chillies and chilli sauces out of reach of children and pets.
