Sow 6 mm deep in warm soil
Start seed indoors 8–10 weeks before the last frost and keep the soil at 21–29 °C, the range given for this variety. Typical for the species: pepper seed germinates in soil at 18–35 °C, and seedlings appear in about 8–9 days at 25–35 °C (figure measured with seed sown about 12 mm deep). Cover the seed with about 6 mm of mix.
Planting out
Move plants outside only after the risk of frost has passed. Space plants 45–60 cm apart in full sun and well-drained soil, and water evenly without overwatering. Ripe yellow pods come about 70–80 days after transplanting.
Stuffing, grilling, pickling
The thick walls hold their shape when stuffed and grilled; the pods are also sliced fresh into salsas and sandwiches or pickled.
What you get
The packet holds 5 seeds of Jalapeno Yellow Jumbo, enough for five plants if every seed comes up. We do not state a germination percentage for this packet. Pepper seed typically keeps about 2 years when stored cool, dark and dry, so unused seed can wait for the next season.
