Why Spring Is the Best Season for Chilli Growing

Spring offers the ideal conditions for starting your chilli growing journey. Warm soil temperatures (above 18°C), increased sunlight, and consistent moisture create the perfect germination environment. Starting early in spring ensures a long growing season, giving your chillies enough time to mature, develop flavour, and achieve maximum heat.

Whether you’re growing in pots, garden beds, or greenhouses, spring sowing sets you up for a bountiful and spicy summer harvest.

Top 3 Chilli Plants to Grow in Spring

Below are our top picks for chilli varieties that thrive in spring, pack serious heat, and grow well in New Zealand’s climate.

1. Carolina Reaper Chilli Seeds – The World’s Hottest Chilli

Scoville Heat Units: Over 2,200,000 SHU

Best For: Extreme heat lovers and competition growers

The Carolina Reaper is the undisputed king of heat, officially recognised by the Guinness World Records as the world’s hottest chilli. It boasts a blistering heat level and a surprisingly sweet, fruity flavour — making it a favourite for hot sauce makers and heat chasers alike.

Why it’s perfect for spring: The Carolina Reaper requires a long growing season, making early spring the perfect time to start seeds indoors. With consistent warmth and light, it can produce an impressive yield by mid to late summer.

Growing tips:

• Germinate seeds indoors using a heat mat to maintain 28–32°C.
• Transplant once the danger of frost has passed and soil is consistently warm.
• Use well-drained soil and full sun for best results.

2. Trinidad Scorpion Chilli Seeds – A Wild Scorcher

Scoville Heat Units: Up to 1,463,700 SHU

Best For: Experienced growers and chilli collectors

The Trinidad Scorpion Butch T is another superhot heavyweight, known for its stinging heat and scorpion-like tail. A former world record holder, it delivers an intense heat punch that lingers — ideal for making fiery hot sauces and spice blends.

Why it’s perfect for spring: With high heat requirements and a relatively long maturation time, early spring planting gives the Trinidad Scorpion a head start to reach its full potential before the cooler months arrive.

Growing tips:

• Sow seeds indoors 10–12 weeks before your last frost date.
• Maintain high humidity during germination.
• Feed regularly with potassium-rich fertiliser to boost fruiting.

3. Bhut Jolokia Chilli Seeds – Flavour Meets Fire

Scoville Heat Units: 1,000,000+ SHU

Best For: Culinary use and fermenting hot sauces

The Bhut Jolokia, also known as the Ghost Pepper, was the first chilli to break the 1 million SHU mark. What sets it apart is its complex flavour — smoky, slightly fruity, and slow-building in heat. This makes it a favourite among chefs and chilli fermenters who want both intensity and depth.

Why it’s perfect for spring: Bhut Jolokia needs a long, hot growing season to fully ripen. Planting in early spring ensures enough time for the chillies to reach peak ripeness before the season ends.

Growing tips:

• Use a propagation dome or plastic wrap to retain heat during germination.
• Ensure daily sunlight or supplement with grow lights.
• Support plants as they grow tall and heavy with fruit.

Growing Tips for Hot Chilli Success

No matter which superhot chilli you choose, here are a few universal tips to maximise your harvest:

Start Early, Stay Warm

Chillies are heat lovers. Use seedling trays with a heat mat or warm windowsill to maintain optimal temperatures during germination.

Don’t Overwater

Chilli plants dislike soggy roots. Use well-draining soil and water only when the topsoil feels dry.

Provide Full Sun

Chillies need at least 6–8 hours of direct sunlight per day. If growing indoors, consider using full-spectrum grow lights.

Feed Regularly

Use a balanced fertiliser during the vegetative stage, then switch to a potassium-rich mix during flowering and fruiting.
