Growing Peppers from Seed: How to grow Peppers - Top 12 Tips

Our Top 12 Tips

How to Grow Peppers
1. Use Fresh Seeds
When perfectly stored, pepper seeds can be viable for up to 25 years, but generally 2-5 years is more realistic for good germination rates. The older the seeds get, the less likely they will sprout. Store seeds in a cool, dark, dry environment. Remember, seeds are meant to be grown, so plant them! Of course we still plant old seeds (a few years old) all the time, because they can still sprout. Just be aware that the germination rate will be lower, so you can expect that not every seed will sprout.


80-90˚ F for pepper seed germination
2. To germinate, keep pepper seeds consistently warm and moist, 80-90˚ F is ideal for most successful germination. Use a seedling heat mat to bring the temperature up, and don't try germinating peppers in a cold room or greenhouse as the temperatures could drop which lowers your chance of success. Once sprouted, thin seedlings so they don't crowd each other, one plant per pot is recommended. We often try to gently pull or separate out the extra pepper seedlings out and then plant them into more pots if we have the space!

3. Be patient.
Some super hot pepper seeds are slow to germinate and can take 4-6 weeks to germinate, while many of the fastest growing peppers take 7-10+ days. This is even when kept super warm, so don't give up on them.

4.
Start Peppers indoors 6-8 weeks before the last frost date. 
Peppers like warm weather, so keeping them indoors until it's warmed up to about 60-70˚ F at night is important. Peppers are very frost sensitive and get stunted in temperatures below 50˚ F or in cold soil. You can start them even earlier IF you have the room indoors to keep them warm and cozy until all chance of frost has passed and the temperatures warm up to a consistent 60˚ F+ at night. Most peppers will have stunted growth if in cold temperatures below 50˚ F. If you keep them growing indoors longer, just make sure to pot them up as their roots grow so they don't get root bound in the container.

Note: The purple-toned pepper seedling above is normal, some pepper varieties especially purple ones tend to have purple stems and leaves at first when grown outdoors. Most peppers will typically revert to green once outside in the full sun (though they may retain purplish-stems).
 

Don't overwater Pepper Seedlings

5. Don't Overwater Pepper Seedlings!
This is a common mistake by many gardeners, experienced or not. We tend to overwater seedlings – and peppers hate wet, soggy roots. So make sure to let the soil dry out a bit between watering your pepper plants. Make sure to use well-draining planting mix in pots with plenty of drainage. If you see yellow leaves on your pepper plants, and they are starting to droop, this is often a sign that the soil is too soggy – make sure to let the soil dry out a bit between watering. Your peppers will be much happier! Don't "overlove" them with too much water!

 Pinch Off first Blossoms on Pepper Plants

6. Pinch off first Pepper Blossoms
Pinch off the first few blossoms on your pepper seedlings to encourage them to put their energy into growing stronger roots and foilage, so you'll have more peppers later. 





7. Give them a breeze or a brush with your hands.
Once sprouted, you can encourage your pepper seedlings to grow stronger, thicker and stockier by simply brushing the seedlings with your hands daily, or by adding a fan for a light breeze on the peppers for a few hours a day. In addition to growing stockier, this will help prevent damping off, a common ailment of seedlings that causes them to wither and die after sprouting.

Growing Peppers from Seed: Hardening off Pepper Seedlings

8. Harden Off Pepper Plants before planting outdoors.
 
This means if you have started them indoors you should bring them out for a few hours a day, working up to a full day and eventually overnight over a week period (or 10 days if you have time). This will acclimate the outdoor weather, sun, breezes, etc so they won't be shocked when transplanting into the garden or outdoor container.

9. Plant in Full Sun!
Make sure the pepper plants get full sun, at least 6-8 hours of sunlight is best. We find that peppers also can do well with dappled shade for a part of the day, as long as they get 6-8 hours of good sunlight.


How to grow peppers from seed - Sunscald on Pepper

Speaking of sun, do you ever get white spots on your peppers? If you're getting a lot of sunscald on your peppers, grow pepper companions like bush beans around your peppers to keep the peppers from getting exposed to too much sun. A bonus of growing beans along with your peppers is that they naturally add nitrogen to the soil via their nitrogen fixing root nodules that transform environmental nitrogen into nitrogen underground that benefits other vegetables like peppers. This type of natural soil nutrition is better than using store-bought high-nitrogen fertilizers, which can cause pepper plants to just grow bushy and not produce pods. Read on...

Growing peppers from seeds - Don't overfertilize peppers with too much Nitrogen

10. Don't Over-fertilize with Nitrogen:
Peppers are light feeders, but will benefit from a regular feeding of a well-balanced, organic fertilizer or compost tea. Homemade compost is also highly recommended for adding to your soil in your garden every year to keep it packed with natural nutrients. Avoid high nitrogen fertilizers later in the season. They create lush foliage, but few peppers.
 Growing Peppers from Seed: Pepper Pollination

11. Plant Lots of Flowers Near Your Pepper Garden
Do your pepper plants have flowers but no peppers? Pollination is key to growing successful peppers, and while peppers can self-pollinate with the wind, pollinators can really help seal the deal. Invite pollinator bees and attract beneficial insects by growing lots of natives and flowers in your garden. Don't use pesticides! Make sure the peppers are grown in a spot with good air circulation and spaced properly. There are also other reasons that peppers have flowers but no peppers such as extreme temperatures.

 Growing Peppers from Seed: Pepper Harvesting

12. Pepper Harvesting
Many peppers are harvested at an immature stage such as the traditional bell pepper – it's harvested green, even though most varieties will mature to red, purple, orange, or yellow. Chile peppers can be harvested at any stage of growth, but their flavor doesn't fully develop until maturity. We encourage you to taste one pepper, if it still tastes green, let it ripen for another week or so before trying another pepper for the desired ripeness and flavor. Many chile peppers' flavors are intensified by roasting!

Grow Peppers in Pots

Grow peppers in pots

Peppers grow wonderfully in containers. One great reason to grow peppers in pots is that they are cold-sensitive plants, so if you have a late spring frost or an early autumn frost, you can bring in your potted pepper plants to a warm sheltered location to keep them from being frozen. 

Here are some of the best peppers to grow in pots.
