Welcome to our beginner’s guide to starting pepper and onion seeds! Whether you’re a seasoned gardener or just starting, this step-by-step guide will walk you through the process of successfully germinating and nurturing your pepper and onion seeds.

1. Gather Your Materials:

  • Seed trays or pots
  • Seed starting mix
  • Seeds (peppers and onions)
  • Watering can or spray bottle
  • Plastic dome or plastic wrap (optional)
  • Grow lights or sunny window

2. Prepare Your Seed Trays or Pots:

  • Fill trays or pots with seed starting mix, leaving about ¼ inch from the top.
  • Lightly tamp down the soil to remove any air pockets.
  • Water the soil thoroughly and allow it to drain.

3. Starting Onions and Peppers:

  • Follow the instructions on the seed packet for planting depth and spacing.
  • Place 2-3 pepper seeds in each cell or pot.
  • For onions, feel free to over-seed, planting as many as 15 or 20 seeds in a pot.
  • Cover the seeds lightly with soil and gently press down.

4. Provide Optimal Growing Conditions:

  • Place the seed trays or pots in a warm location with indirect sunlight or under grow lights.
  • A heat mat will create the optimal environment for heat-loving seeds like peppers and onions.
  • Maintain a consistent temperature of around 70-80°F (21-27°C) for optimal germination.
  • Keep the soil consistently moist but not waterlogged by watering from the bottom or using a spray bottle.

5. Monitor and Care for Your Seedlings:

  • Once the seeds have germinated, remove any plastic domes or plastic wrap.
  • Continue to provide adequate light and water as needed.
  • Thin out weaker seedlings, leaving only the strongest one per cell or pot.
  • Fertilize your seedlings with a diluted liquid fertilizer every 2-4 weeks.
  • As your onions grow, trim the tops to train them to stand up. As they grow, keep them trimmed to 5 or 6 inches. This will strengthen them and help them to grow straight.

6. Transplanting Your Seedlings:

  • When the pepper seedlings have developed their first true leaves and are about 2-3 inches tall, they are ready to be transplanted into larger pots or the garden.
  • Harden off your seedlings by gradually exposing them to outdoor conditions for 7-10 days before transplanting.
  • Onion seedlings can be kept in their pots until the time of planting outside.
  • After hardening them off, cut the pots open and detangle the roots. Onion roots are tough and wiry and not prone to damage.

7. Planting in the Garden:

  • Choose a sunny location with well-drained soil for planting your pepper and onion seedlings.
  • Dig holes slightly larger than the root balls of your seedlings and gently transplant them into the ground.
  • Plant onions 4 to 6 inches apart, depending on the variety.
  • Plant peppers 8 to 12 inches apart, also depending on the variety.
  • Consider companion planting. Basil is a good companion for peppers, acting as a natural pest repellent.
  • Onions are a good companion for many vegetables: peppers, tomatoes, carrots, lettuce, brassicas, beans, and herbs.
  • Water the newly planted seedlings thoroughly and continue to water as needed.

8. Nurturing Your Onions and Peppers to Maturity:

  • Mulch around the base of your plants to help retain moisture and suppress weeds.
  • Water regularly, especially during dry spells, and fertilize every 4-6 weeks with a balanced fertilizer.
  • If you are building healthy soil, then a top-dressing of compost is all you need, once a season.
  • Watch for pests and diseases, and take appropriate measures to control them.
  • Harvest your peppers and onions when they reach maturity, and enjoy the fruits of your labor!

Conclusion: Peppers and Onions are Great Companions

Congratulations! You’ve successfully started pepper and onion seeds and nurtured them to maturity. With a little time and care, you can enjoy a bountiful harvest of homegrown peppers and onions to enjoy in your favorite recipes. They are great companions in the kitchen and in the garden.
