How to Grow Peppers from Seed

The first step in learning how to grow peppers is selecting high-quality seeds from a reputable source, which is essential for a successful crop. In the following step-by-step guide, we’ll cover the process of germinating and growing peppers from seeds:

  1. Fill seed trays or small pots with a moist, well-draining seed-starting mix.
  2. Plant seeds about 1/4 inch deep and cover lightly with soil.
  3. Place the seed trays in a warm location (70-85°F) to encourage germination. Pepper seeds typically germinate within 7-14 days, but some varieties may take longer.
  4. Keep the soil consistently moist but not waterlogged, and provide bright, indirect light.

How to Plant Peppers: Nursery Plants & Transplanting Pepper Seedlings

Whether you’re starting with pepper plants from a nursery or transplanting your own seedlings, the planting process is similar. Follow these steps to ensure a successful transplant:

  1. Choose healthy plants with strong stems and green leaves, or wait for your seedlings to develop at least two sets of true leaves.
  2. Harden off your pepper plants or seedlings by gradually exposing them to outdoor conditions over a week to 10 days.
  3. Select a planting location that provides at least 6-8 hours of sunlight, as peppers need plenty of sun to thrive.
  4. Amend the soil with compost or aged manure to improve drainage and fertility.
  5. Space the plants or seedlings 18-24 inches apart in rows 24-36 inches apart.
  6. For nursery plants, dig a hole slightly larger than the root ball of the pepper plant. Gently remove the plant from its container, taking care not to damage the roots. For seedlings, dig a hole the same depth as the seedling container.
  7. Place the plant or seedling in the hole, ensuring that the top of the root ball is level with the surrounding soil (for nursery plants) or at the same depth as in the seedling container (for seedlings). Fill in the hole with soil and gently firm it around the base of the plant.
  8. Water the plant or seedling thoroughly to help settle the soil and establish the roots.

Pepper Plant Care

Proper pepper plant care is essential to a successful harvest. Here are some tips to keep your plants healthy and productive:

  1. Water consistently, providing about 1-2 inches of water per week. Avoid overwatering, as this can lead to root rot and other issues.
  2. Apply a balanced, slow-release fertilizer at planting time and again when the plants start to produce fruit.
  3. Monitor for pests, such as aphids, flea beetles, and pepper maggots. Employ organic or chemical controls as needed.
  4. Stake or cage taller pepper varieties to provide support and prevent fruit from touching the ground.

Growing Peppers in Containers

If you have limited outdoor space or simply prefer container gardening, learning how to grow peppers in containers can be a rewarding alternative. With the right approach, you can successfully cultivate a variety of peppers in pots or other containers. Here are some tips for growing peppers in containers:

  1. Choose the right container: Select a container with a minimum depth of 12 inches and a similar diameter to accommodate the pepper plant’s root system. Ensure that the container has adequate drainage holes to prevent root rot.
  2. Use high-quality potting mix: Fill the container with a well-draining, high-quality potting mix. Avoid using garden soil, as it can become compacted and limit root growth.
  3. Select suitable pepper varieties: Some pepper varieties are better suited for container gardening than others. Look for compact or dwarf varieties that won’t outgrow their containers. Examples include Bird’s Eye, Patio Fire, Cajun Belle, and Jingle Bells.
  4. Provide ample sunlight: As with in-ground pepper plants, peppers grown in containers need at least 6-8 hours of sunlight daily. Place your containers in a sunny location or use a grow light to supplement natural light.
  5. Water consistently: Container-grown peppers typically require more frequent watering than those grown in the ground. Monitor the soil moisture regularly and water when the top inch of soil feels dry to the touch.
  6. Fertilize regularly: Peppers in containers may need more frequent fertilization, as nutrients can be washed away with each watering. Use a balanced, slow-release fertilizer or a liquid fertilizer formulated for vegetables, following the manufacturer’s instructions.
  7. Stake or cage if necessary: Some pepper plants may require support as they grow. Use stakes or small cages to help keep your plants upright and prevent them from toppling over.

Harvesting and Storing Your Peppers

When your peppers have reached their mature size and colour, it’s time to harvest. Follow these steps to ensure a bountiful harvest:

  1. Use clean, sharp scissors or pruning shears to cut the peppers from the plant, leaving a short stem attached to the fruit.
  2. Handle the peppers gently to avoid bruising or damaging the fruit.
  3. Harvest peppers regularly to encourage continuous production.

To store your peppers, follow these guidelines:

  1. Store fresh peppers in the refrigerator for up to two weeks. Place them in a plastic bag or container with a paper towel to absorb excess moisture.
  2. Freeze peppers by cutting them into desired-size pieces and spreading them out on a baking sheet. Freeze until solid, then transfer to an airtight container or freezer bag for long-term storage.
  3. Dry peppers by hanging them in a well-ventilated area, using a dehydrator, or placing them in an oven on the lowest setting.

Pepper Companion Plants

Incorporating pepper companion plants in your garden can not only boost the growth and overall health of your pepper plants, but also help deter pests, attract beneficial insects, and create a more visually appealing garden. Companion planting is a gardening technique that involves planting different species together, which can benefit each other in various ways. Here are some excellent companion plants for peppers and the advantages they offer:

  1. Basil – This fragrant herb not only improves the flavour of peppers but also repels pests such as aphids, spider mites, and whiteflies. It’s also thought to increase pollination by attracting bees and other beneficial insects.
  2. Marigolds – These bright, cheerful flowers are known for their ability to deter pests like nematodes and whiteflies. They also attract beneficial insects, such as ladybugs and lacewings, which can help control aphid populations.
  3. Onions – Planting onions near your peppers can help repel pests like aphids and thrips, thanks to their pungent aroma. Additionally, their dense foliage can help suppress weed growth, reducing competition for nutrients and water.
  4. Tomatoes – Tomatoes and peppers share similar growing conditions, making them good companions in the garden. They can be interplanted to save space and make the most of available resources. However, it’s important to note that they are also susceptible to some of the same diseases, so proper crop rotation and pest management are essential.
  5. Chives – These versatile, onion-flavoured herbs can help deter aphids and other pests while also providing a flavorful addition to your meals.


Mastering the art of how to grow peppers can be an incredibly rewarding experience, providing you with a diverse and flavorful bounty.
