Starting Red Knight Pepper Seeds Indoors

Like all peppers, Red Knight thrives when started indoors before transplanting outdoors. Follow these tips for strong seedlings:

  1. Start Early: Begin seeds indoors 8–10 weeks before your last spring frost.

  2. Temperature: Maintain soil warmth at 75–85°F for best germination. A heating mat is very helpful.

  3. Planting Depth: Sow seeds about ¼ inch deep in a well-draining seed-starting mix.

  4. Moisture: Keep the soil evenly moist but not soggy. Use a humidity dome if needed.

  5. Light: Provide 14–16 hours of bright light daily to prevent leggy seedlings.

Transplanting Seedlings Outdoors

When your Red Knight seedlings are 6–8 weeks old and the danger of frost has passed, it’s time to harden them off and transplant.

  • Spacing: Place plants 18–24 inches apart with 24–36 inches between rows.

  • Soil Requirements: Fertile, well-drained soil with a pH between 6.0–6.8 is ideal. Enrich with compost for strong growth.

  • Sunlight: Choose a location with full sun exposure (at least 6–8 hours daily).

  • Fertilizer: Add a balanced fertilizer at transplanting to promote healthy root systems.

Caring for Red Knight Pepper Plants

  • Watering: Provide 1 inch of water per week. Consistent watering prevents blossom end rot and improves fruit development.

  • Mulching: Helps retain soil moisture and regulate temperature.

  • Fertilization: Side-dress with fertilizer once fruit begins setting.

  • Support: Plants may require cages or staking to support heavy loads of large peppers.

  • Pest Watch: Keep an eye out for aphids, flea beetles, and cutworms. Row covers early in the season provide extra protection.

Harvesting Red Knight Peppers

Red Knight peppers can be harvested green for fresh, crisp flavor or left to fully mature to a deep glossy red, which offers maximum sweetness and nutrition.

  • Cut, Don’t Pull: Use scissors or pruners to harvest peppers to avoid damaging plants.

  • Frequent Harvests: Picking regularly encourages plants to continue producing throughout the season.
