Serrano Tampiqueno Hot Pepper Seeds

Start Serrano Hot Pepper seeds indoors 8–10 weeks before your last frost date. Sow ¼ inch deep in a phosphorus-rich, well-draining mix and keep soil temperature consistently between 70–85°F (21–29°C). Under the right temperature, Serrano Pepper hot seeds germinate in 7 days, if the temperature is lower, germination time stretches toward 21. Once seedlings are a few inches tall, plant them outdoors 12–18 inches apart. or go with one plant per container. Don't rush the transplant date, as cold soil below 55°F at night stalls root development. Serrano Pepper hot prefers warm conditions to grow and produce fruits.

Hot Pepper Serrano plants need a minimum of 6 hours of direct sun daily. Soil should be fertile, organically rich, and well-drained — work compost into the bed before planting if your ground is sandy or compacted. Keep moisture even throughout the season, as inconsistent watering is one of the main causes of blossom drop. Container plants dry out faster than garden beds in summer heat, so check them daily.

After transplanting, these plants want only warmth and regular watering. Stake taller specimens or fit a small cage early — fruiting branches carry real weight and snap in wind without support. Harvest runs from summer into early fall: pick green for a sharper, grassier heat, or leave fruits to ripen fully red for a slightly softer flavor. Wear gloves when touching fruits, because even short contact causes irritation.
