Growing Tips

The Thai Red Chili is a spicy heirloom pepper that requires warm and sunny conditions. It grows best in rich, well-draining soil. Keep the soil temperature between 80–85 F for optimal germination, using a heat mat to help keep the soil warm.

When to Grow

Thai Red Chili peppers thrive in the warmth of late spring through summer. Start indoors in bright light 8-12 weeks before the last frost date. Transplant outdoors after the last frost when both soil and air temperatures have warmed. Check your local area’s frost dates to determine the best planting time.

How to Sow and Plant

Sow seeds about 1/4 inch deep in well-draining soil. Keep the soil consistently moist but not waterlogged, and ensure the seeds receive ample light. Once seedlings have true leaves and outdoor temperatures are warm, transplant spacing them 14-18 inches apart for good air circulation. For container planting, use pots at least 12 inches deep with good drainage​.

How to Grow

Thai Red Chili plants need around 8-12 hours of sunlight daily. Water deeply and regularly, keeping the soil moist but not soggy. Fertilize every 4–6 weeks with a balanced, low-nitrogen fertilizer to support healthy growth and fruiting. Pruning early flowers can encourage bushier growth and higher yields. Harvest when the fruit is a vibrant red color.

How to Save

  • Peppers are mainly self-pollinating, but bees occasionally work pepper flowers as well.
  • To be absolutely sure that you will not have any crossing, different varieties should be isolated by at least 500 feet.
  • It is a good idea to wear gloves when working with very hot peppers, and to consider wearing a mask when working with a large quantity of dried seeds.
  • To save seed, allow the fruit to mature fully; then simply remove seeds.
  • Let seeds dry for a week before storing them in a jar.
  • Pepper seeds will remain viable for up to 5 years.
