When to Grow

Timing is important for a successful pepper harvest. Start seeds indoors approximately 8-12 weeks before your area’s last expected frost date. Once the danger of frost has passed and the soil has warmed, it's safe to move the plants outdoors. We recommend you to check local frost dates to make sure that you’re timing your planting optimally. If you’re not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Start Filius Blue pepper seeds indoors by sowing them about 1/4 inch deep in a high-quality seed-starting mix. These seeds need warmth to sprout, so keep the temperature between 80-85F for optimal germination. When transplanting, space plants about 14-18 inches apart in garden beds or large pots to give them ample room for airflow and growth.

How to Grow

Water regularly, especially during flowering and fruiting, but avoid waterlogging the roots. Using a layer of mulch can help retain soil moisture and regulate soil temperature, particularly during hot weather. Fertilize your plants with a balanced fertilizer once they begin to flower and continue every 2-3 weeks throughout the growing season for optimal yields and vibrant foliage.

How to Save Seeds

  • 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.
  • To save seed, allow the fruit to mature fully; then simply remove seeds.
  • 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.
  • Let seeds dry for a week before storing them in a jar.
  • Pepper seeds will remain viable for up to 5 years.
