About

Tam Jalapeno Pepper (Capsicum Annuum) is a mild-heat variety developed at Texas A&M University — bred specifically to deliver classic green Jalapeno flavor without much intensity. Plants reach 18–24 inches tall and produce glossy, smooth-skinned fruits just under 3 inches long; leave them on the vine and they ripen from green to red, gaining sweetness as they go. At 1,000–1,500 Scoville Heat Units, the Jalapeno tam Pepper sits well below standard jalapenos, which makes it genuinely useful in the kitchen for fresh slicing, pickling or cooking. It grows in USDA Zones 4–11 like an annual; in zones 9–11, plants can overwinter and behave more like short-lived perennials.

How to Grow & Harvest

Sowing & Timing

Start Tam Jalapeno Pepper seeds indoors 7–9 weeks before your last frost date. Sow 1/4 inch deep in moist seed-starting mix. Do not use garden soil, which compacts and suffocates tiny roots. Keep temperature at 80–90°F and Tam Jalapeno Pepper seeds germinate in 7–10 days.  If the temperature is less than 70°F and you will be waiting three weeks, maybe more. You may consider using a heat mat under the tray to reach the necessary temperature. 

Soil, Watering & Fertilization

Jalapeno tam Pepper requires full sun, at least 6-8 hours. In partial shade, the plant grows fine but the amount of fruit drops. Soil should be well-drained with pH around 6.5. Compacted or waterlogged ground causes root stress that leads to leaves yellowing. Water Jalapeno Chili Hot Peppers at the root zone once a week or when the top inch of soil dries out. The green Jalapeno Pepper's drought tolerance, which means it can handle infrequent watering better than most peppers, but consistent moisture still produces better fruit.

Growth & Harvest

Stake the plant before heavy fruiting begins. The single plant produces 23–30 peppers, and their weight will lean plants sideways without support. Feed monthly with balanced slow-release fertilizer. Do not use too much nitrogen, as it pushes foliage growth, not peppers. Pinch the first flower or two if you want the plant to become bushy before it starts fruiting. Harvest green Jalapeno Pepper for the classic crisp flavor, or leave fruits to turn red for a deeper, slightly sweeter heat. But don't leave overripe fruits on the plant, as they signal the plant to stop producing.
