Thai Pepper
Capsicum annuum 'Thai'
The highest ratio of yield to floor space of anything we grow.

One plant is usually enough
A healthy Thai pepper produces in the hundreds - small upward-pointing pods carried in clusters above the foliage, which is both ornamental and easy to pick. Plan for drying or giving away most of it before you plant three.
Start indoors eight weeks ahead
Sow at 80-85F with bottom heat. Being Capsicum annuum it germinates more readily than a chinense superhot, but it still wants warmth and patience. Transplant only once nights hold above 55F.
Containers suit it
Compact and upright at eighteen to twenty-four inches, it finishes fine in a three gallon pot and makes a genuinely attractive patio plant. Container plants dry out faster, so check daily in high summer - and a dried-out pepper drops its flowers.
Feeding and water
Moderate feeding, shifting to low nitrogen once flowering begins. Steady water for a good set; mild water stress late in the season pushes capsaicin up, which is usually what you want here.
Heat is real but clean
At 50,000 to 100,000 Scoville a Thai pepper is roughly twice a cayenne and ten times a jalapeno. The burn arrives fast, sits at the front of the mouth, and fades relatively quickly - different from a superhot in kind, not just degree, which is why it works as a cooking chile rather than a novelty.
Support the loaded plants
A plant carrying two hundred pods gets top-heavy despite the compact habit. A single stake prevents it splaying open in a storm.
Pests and disease
Aphids on the growing tips are the main issue, particularly on container plants. Bacterial leaf spot in wet weather; sunscald on exposed pods. Rotate away from tomatoes, potatoes and eggplant.
Drying
The pods dry well on the plant at the end of the season, or strung on a thread indoors - the thin walls mean they air-dry without moulding, unlike a thick-walled pepper. Two to four weeks somewhere warm and airy until brittle. Store whole and grind as needed.
Overwintering
Being compact and container-friendly, Thai peppers overwinter easily. Cut back hard, bring indoors somewhere bright above 55F, water sparingly. A second-year plant starts producing weeks earlier.
