Growing Tips
The Big Jim pepper, a large, mild- to medium-heat heirloom chili, thrives in warm conditions and full sun. You can use a heat mat to help warm up the soil and speed up germination. These peppers prefer nutrient-rich, well-draining soil.
When to Grow
Start Big Jim pepper seeds indoors in early spring, around 8-12 weeks before the last expected frost. Transplant seedlings outdoors only after all frost risks have passed, and nighttime temperatures stay above 65 F. In regions with shorter growing seasons, early indoor starting ensures a full harvest season.
How to Sow and Plant
Sow seeds 1/4 inch deep in a well-draining seed-starting mix, keeping the soil consistently moist but not waterlogged. Once seedlings reach 4–6 inches tall and have multiple true leaves, harden them off by gradually exposing them to outdoor conditions. Space mature plants 14-18 inches apart in soil amended with compost, as they can grow quite tall and need room for their large, dense foliage.
How to Grow
Big Jim peppers require consistent watering, though they tolerate short dry spells well. Deep, infrequent watering encourages a strong root system, and mulching helps retain soil moisture. Use a balanced fertilizer during early growth and switch to a high-phosphorus formula once flowers appear to support fruit production. Staking may help as plants become heavy with fruit.
How to Save
- Peppers are mainly self-pollinating, but bees occasionally work pepper flowers as well.
- To be absolutely sure that you will not have any crossing, different varieties should be isolated by at least 500 feet.
- It is a good idea to wear gloves when working with very hot peppers, and to consider wearing a mask when working with a large quantity of dried seeds.
- To save seed, allow the fruit to mature fully; then simply remove seeds.
- Let seeds dry for a week before storing in a jar.
- Pepper seeds will remain viable for up to 5 years.
