Grow Peppers From Seed


It’s that time of year to get the peppers ready for the garden, if you haven’t already. Here in zone 5a we are just getting past our frost danger. We are usually in the clear once we pass Memorial Day. In this post I am going to discuss how to grow peppers from seed. The pepper plants are warm loving plants but can still be grown in the north, you can grow peppers from seed indoors to get a jumpstart on growing. If you live in the desert with very poor soil, this is a good container plant as well. Either way, no matter where you live you can grow peppers from seed and plant them in your garden or transplant to a larger container for container gardening.
Grow Peppers from Seed

Start Peppers from Seed

To start peppers from seed, you will need the following items

  • Container – with drainage holes
  • Organic Soil
  • Seeds
  • Water
  • Plastic Dome or Plastic Wrap

If you have a short growing season or the soil isn’t great for Peppers, then start seeds indoors, approximately 8 to 10 weeks before planting in the ground or in an outdoor container.

Fill your container with organic potting soil, make a space in the dirt a 1/4″ down and place the seed in the hole and cover the seed with the soil. Water the seed well and let excess water drain out the bottom of the container. Place a plastic dome or plastic wrap over the top to create a greenhouse effect and place under a grow light or sunny window. Each type of pepper has their own time for germination.

The peppers I started from seed are, Giant Sweet Peppers, Chili Medium-Hot Peppers and Poblano Peppers. I have never grown Poblano Peppers before so we will see how they do. Bell Pepper Plants

Heirloom Variety Giant Pepper

This heirloom variety giant pepper, is a large fancy, nice quality sweet pepper, that is bell type. The pepper grows 4″-5″ x 3.75″, mostly four love fruits, thick dark green to red flesh. This giant pepper grows to 28″ to 30″ tall with thick stems to ensure continuous harvest and high yields.
Giant Sweet Bell Pepper Plant

This seed takes 10 days to germinate. Wait to transplant outdoors when the night stays 50 degrees or above. Transplant into warmed soil with full sun. Harvest is approximately 76 to 80 days from transplant date. Regularly harvest peppers from the plants to continue crop growth, This pepper is an excellent source of vitamins A and C.

Chili Pepper – Medium-Hot

This is a spicy variety if you didn’t get it from the name. I have not grown this variety either. I have grown basic jalapenos but not this kind. This kink is Big Jim’s Chili Pepper Medium-Hot. These Fleshy tapered pods average 7″ to 8″ long, and about 4 oz at maturity.
Hot Pepper Plant

This variety was developed by Dr. Nakayama has held the world’s record for the longest chili pepper grown to 13″ with superior yield. The plants produce 25-40 pods. Start indoors 6-8 weeks before the last frost date and transplant into fertile and fell tilled soil and space 18″ to 24″ apart.

When this plant is ready to harvest, all the fruits ripen all at once in 75 to 80 days from transplant. The plants can be pulled and hung upside down for drying. Good for frying, salads and grinding into chili powder or having fresh.

Ancho/Poblano Chile Pepper

The Ancho/Poblano Chile pepper is one of the most popular chilies in Mexico. These are an heirloom seed too. The green 3″-6″ pobano is most often stuffed with cheese or meat for chilies rellenos. This pepper is dark, reddish-brown, dried ancho is used in a variety of sauces, such as the traditional “mole poblano”.

This pepper likes warm soil. Start these indoors, for mild climates 2 to 4 weeks after last frost and for us in the north, start 8 to 10 weeks indoors before transplanting outside. Ideal soil temps are 70 to 90 degrees for germinating seeds outdoors by direct sow. If you started them indoors wait to move them outdoors until the daytime temperature is 70 degrees or above and nighttime temperatures don’t go below 55 degrees. When planting outside, space them 24″ to 36″ apart and put in full sun.

Poblano Pepper Plant

Planting Tips for Peppers

Peppers like to be planted by tomatoes, they are good companion plants for the garden. Before transplanting outside, it’s good to harden them off. The term hardening them off means, to put the plants outdoors during the day in a sheltered warm place, then bring back in at night for a week to 2 weeks. Depending on how your weather is in your area.

Peppers like a very slightly acidic soil to neutral (6.5 to 7 pH). Peppers need 6 to 8 hours of sunlight to produce and if growing indoors, they need to grow under a grow light for 14 to 16 hours.

Make sure the soil is amended before planting the peppers, you want to give them the best start possible. Make sure you are weeding around the pepper plants. Weeds steal nutrients from the plants, so use a weed barrier or mulch and pull weeds as soon as you can.
Poblano Pepper

If you start to see signs of bottom rot on the fruits, the plant is lacking calcium. Get some powdered milk and sprinkle around the base of the plant. If it continues, add more powdered milk, this will fix the problem.

If the plant flowers great but then hardly any or no fruits, the plant is nutrient-deficient and needs magnesium. To help this issue, place Epsom salts around the base of the plant when needed.

After harvesting your first crop, it’s a good idea to give the plant some organic fertilizer to give the plant energy to produce more peppers. Some people like yellow, orange and red peppers. Just keep them on the vine longer. The peppers start out green but feel thin.

Once the peppers start to take on color they get thicker and ripen for harvest. When it’s time to harvest, use a sharp clipper to clip off the pepper. This will keep from damaging the plant and other peppers. Sometimes peppers are hard to just come off, and it could damage the plant if the fruit doesn’t snap off easily.

Happy Planting!

Growing peppers is pretty easy. They don’t really require much but sun and some water. I have always had good luck with growing peppers. I have grown in my raised bed, containers and regular garden too. If you have never planted peppers before, this should help you get them started and with a nice crop!

I hope you found this post helpful, especially for someone who has never planted and grown peppers before. There are other types of peppers too. There are many types of pepper seeds to choose from.

Let me know what peppers you are growing this year in the comments below, I would love to hear from you!

Are you growing in a container, raised bed or ground garden?

  1. This is excellent gardening teaching. I like gardeners and the site of good gardening. It is refreshing, and invokes beauty, and reminds me of the Garden of Eden where every beautiful plant was in place. As for planting pepper, I tried it this season, by planting the sachet seeds I bought at Walmart, unfortunately, they weren’t good seeds, non-germinated. So I had to buy the plant type. That one is coming up well. Together with the tomato plants.

    But I’m taking note of your instructions on how to do the indoor planting, when, and how. And I can see that the temperature rating is very important for the health and survival of the plants. You recommended a temperature at 70 degrees and nighttime temperatures. Also, the spacing is equally worth attention.

    I naturally like peppers, the giant sweet peppers, Chilli, Medium-Hot-Peper, and the Poblano, I consume a lot of peppers during the cold seasons mostly the spicey ones. So I will make out time to follow your gardening training so that I can grow them organically for my use yearly.

    Thanks for sharing!

    Planting Tips for Peppers

  2. Hello Chris! I already came across your website before and this post interests me as well. Me and my siblings do love our food to have a bit of spiciness in it. Currently, we use chili flakes and chili oil. You gave me such a great idea to start planting instead so we can continuously have some fresh peppers around. Thanks for giving out these tips!

    • Hi Jeelah,

      Planting your own peppers is much better and fun to grow.  There are so many varieties from very mild to very, very hot like ghost peppers.  I like medium heat myself.  I just planted my pepper seedlings in my garden this weekend.  Let me know how your peppers do if you plant them.  Thank you for your comments.

  3. Hi there,

    What a fascinating post! Thank you for sharing it. It will help me finally grow my peppers correctly:) I’ve never had luck with them, and the reason is that I love watering my plants. I must pay attention to this and not give too much water to peppers plants. I’ll follow your tips, and I’ll see how it goes.

    I just would like to know. After picking the peppers, will they grow again, or should I plant new seeds?

    Thanks a lot!

    • Hi

      I don’t plant more.  The plants seem to give off more peppers as you pick them.  I think you are good!  Thank you for your comments.

  4. Hi Chris, I enjoyed reading about your peppers. Do you use your own seed? or Do you use the seed from the plant shop?

    I love the idea of using Powdered Milk and Epsom salts to fix issues with your peppers. It’s a wonderful idea that I will add to my list of tips on gardening.

    Great post.

    • Hi Yvonne,
      I purchased my seeds. I haven’t tried using my own seeds. Maybe I will try it this fall. Thank you for your comments!

  5. I’ve left you a comment on your website. 

    I enjoyed reading about planting peppers from seed to harvesting. You have done a wonderful job by providing some tips on looking out for your chillies and peppers.

    Powdered Milk for calcium deficient plants is a wonderful idea, and so is using Epsom Salts for your plants to provide more flowers.

    I loved the rounding of the images, and it adds a softer appealing look than the normal squared
