Steps

1
Prepare the soil by mixing in large amounts of organic matter like compost, ensuring the area has full sun and well-draining soil.
Tip: Avoid planting where other nightshades (tomatoes, potatoes, eggplants) were recently grown to prevent disease.
2
Sow seeds indoors 8 to 10 weeks before the last spring frost. Plant 3 seeds per pot at a depth of 1/4-inch.
Tip: Soak seeds in water overnight before planting to speed up germination.
3
Maintain soil temperature at 70°F (21°C) or above using a heat mat to encourage faster germination.
Tip: Seedlings usually appear within 2 weeks, but some varieties can take up to 5 weeks.
4
Keep seedlings warm with plenty of light. Thin out the weakest seedling, allowing two plants to grow together in one pot.
Tip: If seedlings become leggy, replant them in a bigger pot up to their lowest leaves for extra support.
5
Harden off seedlings approximately 10 days before transplanting them outdoors.
Tip: Wait to transplant until frost has passed and soil has reached 60°F-65°F.
6
Transplant seedlings 1 inch deeper than they were in their original container and pack soil loosely around them.
Tip: Leave a slightly sunken area around each plant to hold water.
7
Water the plants immediately after transplanting and apply a liquid starter fertilizer.
Tip: Stake the plants immediately to avoid disturbing roots later.
8
Water regularly to maintain consistent moisture, typically providing 1 to 1.5 inches of water per week.
Tip: Ensure soil remains moist but not saturated.
9
Provide at least 6 hours of direct sunshine daily and support plants with cages to prevent bending.
Tip: Cone-shaped wire cages are highly effective for pepper plants.
10
Harvest the peppers once they reach the desired size or color, depending on the variety.
Tip: For Padron peppers, harvest at 1-1.5 inches for mild flavor; they become hotter if they reach 2-3 inches.

Pro Tips

  • Use biodegradable pots if you want to transplant the entire root ball into the garden.
  • If your spring is long and wet, use raised garden beds to improve drainage.
