Chiang-Rai Chilli Seeds

[60 days from transplanting] Also known as “Big Thai”, the Chiang Rai hot pepper originally hails from Thailand, where it’s used in many of their famously spicy-hot dishes. The fruits grow up to 6 inches (13 cm) long and mature more rapidly than many other hot peppers of this type.

Wonderful fresh, dried, or preserved in oil or vinegar. Just remember to use gloves when cleaning them under running water, as the pepper juice can burn the skin.

Scoville Heat Units: 5,000.

Note: If you have access to grow lights and a heated propagator you can start sowing your plants in December and January to give you a head start on the year.

Common Questions

What month should you begin to sow Chiang-Rai Chilli seeds? You should be sowing your Chiang-Rai chilli seeds indoors in January and February. Sowing your seeds indoors before the last frost of the season gives you a longer growing season and allows your chillies to be fully ripen before harvest.

Do Chiang-Rai chilli plants need full sun or shade? The best spot in your garden for Chiang-Rai is a nice sunny spot, however your plant can still grow in a semi-shaded spot. In a full sun position, away from the wind, your chilli plant will produce a lot more fruits.

Does Chiang-Rai die after fruiting? In warmer countries Chiang-Rai plants will grow throughout the year, however in colder areas of the UK your plant will die once Autumn approaches. Sowing and germinating your Chiang-Rai seeds early in the spring will allow a longer harvesting season and produce more ripened peppers. You can't over winter Chiang-Rai as it is too cold for the plant to survive the frosts.
