Chilli plants add a vibrant pop of colour to your garden while delivering a fiery kick to your recipes. The best part? There’s a variety for every gardener, from mild and sweet to tongue-tingling hot.
Understanding Growing Conditions for Chillies
Chilli plants thrive in warm climates, making them a fantastic choice for greenhouses, warm windowsills or sunny patios. Here’s what you need to keep in mind:
- Temperature: Chillies prefer a warm environment, ideally between 18-30°C (64-86°F).
- Sunlight: Chilli plants need at least 6-8 hours of sunlight daily. A sunny windowsill, greenhouse or polytunnel is perfect.
- Watering: Keep the soil consistently moist but well-drained. Avoid overwatering, as it can lead to root rot.
- Fertiliser: Use a potassium-rich fertiliser during the flowering stage to encourage fruit development.
