Like most peppers, serranos grow happily here in North Texas from spring right through until the first freeze. Learn how to transform your serrano harvest into a spicy, green salsa that goes with just about everything.
What Are Serrano Peppers
Serrano peppers are small, hot chiles that grow on 2-3 feet tall, highly productive plants. Registering 10,000 to 20,000 units on the Scoville scale, serranos are considered medium-hot to hot. They are slightly hotter than jalapeños (2,500 – 10,000).
The pepper originated in the mountainous Mexican states of Hidalgo and Puebla. The name comes from the Sierra Mountains of the region. Serrano means: “Of the Sierra”.
How to Grow Serrano Peppers
- For a summer crop, start serrano peppers by seed indoors in mid-February and transplant into the garden in mid-April. For a fall crop, start seeds in late May and transplant in August. Transplants are widely available for purchase.
- Prior to planting, amend your soil with high-quality compost. Space pepper plants 18 to 24 inches apart. Spread hardwood mulch around plants to a depth of 3″.
- For maximum production, keep pepper plants well fertilized and evenly watered throughout the growing season. Fluctuations in
watering can cause blossom-end rot. - Harvest serrano peppers once they reach 2 1/2 – 3 inches long. Serranos can be enjoyed when green or red.
