How To Save Pepper Seeds


Choose Ripe Peppers

The first, and most important step to storing pepper seeds is to choose fully ripened peppers. The reason for this is to ensure that the seeds within the peppers are fully developed.

Saving seeds from fully ripe peppers increases germination rates when you are planting them next season.

For example, if you are storing jalapeño seeds, you’ll want to choose a bright red pepper rather than a younger, green pepper. This is because red peppers are at the final stages of ripening.

How To Know When Peppers Are Fully Ripe

A fully ripened pepper will almost always go through a color change. Jalapeños turn from green to deep black and finally to red when fully ripe. Green bell peppers will eventually turn orange, yellow or red (red bell peppers are in fact just fully ripened green bell peppers!). Even banana peppers will eventually turn a red color.

Not all peppers turn red, for example, our Lemon Spice Jalapeno peppers ripen to a bright yellow color.

Another characteristic of fully ripened peppers is a softer texture. Under-ripe peppers are typically very firm. After ripening, the pepper’s flesh will soften slightly, and a simple *squeeze* will not cause the peppers to crack.

Under-ripe peppers will usually make an audible cracking sound when squeezed. This is especially the case for thicker-skinned peppers, like jalapenos, bell peppers, and banana peppers.

To put it simply, look for these signs that a pepper is fully ripe:

  • Change in color
  • Softer skin (when squeezed)
  • Easier to pick

Remove Seeds Onto a Plate (Not a Paper Towel!)

It seems logical to dry pepper seeds on a paper towel – they wick away moisture, so it should just speed up the process. However, we do not recommend using a paper towel due to the porous surface.

This can cause the seeds to start germinating instead of drying, especially if the air is humid. It is not too common, but to avoid this issue, simply use a ceramic plate, or anything with a smooth surface.

How to Remove Pepper Seeds For Storage

  1. Slice Off Bottoms & Roll Peppers.

    Slice off the bottom of each pepper just above the end. Most of the seeds are located at the top of a pepper. Squeeze and roll the peppers in your hand (using gloves for hot peppers). Allow as many seeds as possible to fall onto your plate. This helps speed up the process and avoid damaging your seeds.Bottom Slice

  2. Slice Peppers in Half.

    Slice the peppers in half, lengthwise to reveal the remaining seeds and placenta.

  3. Detach Placenta.

    Remove the placenta from the pepper using a knife, careful to avoid slicing seeds in half.Pepper Anatomy

  4. Remove Remaining Seeds

    Many seeds will remain embedded in the placenta. You can either remove them manually, or simply let the entire placenta dry on the plate. This will take longer to dry, but once it is dry the seeds will fall off much easier.

  5. Spread Seeds & Allow To Dry

    Keep your seeds in a well-ventilated area for 5-7 days. You can also use a small fan to provide better airflow.

Tip: Be organized! If you are saving seeds from multiple pepper varieties, be sure to dry them on separate, labeled containers to avoid confusing seeds.


How To Dry Pepper Seeds

Allowing seeds to dry takes a while. Just keep them in a well-ventilated room. Airflow and dryness is key! Jostle the seeds around every day to make sure both sides of the seeds are getting dried out.

In a typical climate with around 40% humidity, seeds should be adequately dried within 1 week. If the humidity is higher where you live, you may need to wait a bit longer or provide some additional airflow with a fan.

How To Dry Pepper Seeds

Drying pepper seeds is as simple as allowing the seeds to sit for several days at room temperature.

Steps:

  • Spread pepper seeds out on a plate so few are touching one another
  • Aim a small fan at the seeds on low if humidity is high
  • Jostle the seeds daily, careful not to mix up different seed varieties
  • Test for dryness after 7 days

How Do I Know When Pepper Seeds Are Dry?

If you store your pepper seeds before they are properly dried, you may end up with mold growth or bacteria. This is bad news and can ruin your seeds or infect future plants. To make sure you have a fully dried pepper seed, use this simple method:

  • Break seeds in half – Properly dried pepper seeds should *crack* in half rather than squashing or bending. If they are not 100% firm, they are not yet dry enough to be stored.

Once they are properly dried out, you are ready to store your pepper seeds for several months (or even years!) until it is time to plant.


Save Seeds in Sealed Container

When your pepper seeds are dried, they must be kept dry and cool. Label your seeds and store them in a sealed container. You can use ball jars or heavy-duty Zipoc bags.

Ideally, keep your dried pepper seeds sealed in the refrigerator around 40°F.

If you plan to store your seeds for an extended period of time, keeping a food-grade desiccant packet inside can help keep the seeds fully dry. Buy some on Amazon.

Labeled and Stored Seeds
Always label!

Tip: Always label your seeds! Even if you are only storing one pepper variety, it is best to record the date and type of seed to make things easier later on.

After you have packed away your dried seeds, don’t forget to use the remaining fresh pepper flesh for drying, or one of the many other alternatives for preserving peppers! Don’t let your hard work go to waste.

How Can I Tell If Old Pepper Seeds Are Still Good?

Over years of gardening, you may accumulate old seeds. Pepper seeds can remain growable for several years if properly stored. However, you can run a simple test to determine which seeds are more likely to sprout.

The viability water test – To check old seeds for viability, place them in a glass of water. Wait 24 hours, those that have sunk are viable and will more likely germinate.

Note: Only run this test when you are ready to plant your pepper seeds. After soaking the seeds, they should be planted right away, as the moisture may initiate germination.


Avoiding Disease When Saving Pepper Seeds

One important thing to consider when saving pepper seeds is the possibility of viruses or bacteria. Some viruses are seed-borne, meaning they can be spread from a seed into the plant. Here are a few things to consider before saving pepper seeds.

Never save seeds from a diseased plant. If you suspect that your pepper plant was infected with a disease, whether it be viral or bacterial, don’t save those seeds. Many viruses, including the prevalent mosaic virus, can be seed borne. This puts you at risk of spreading the virus to next year’s plants through this year’s seeds.

Learn more about pepper plant diseases & issues here.

If you have a variety that you really want to continue growing, look into seed sterilization methods to minimize the risk of spreading.

Sterilize seeds if you suspect infection. Depending on where your pepper seeds came from, you may worry that they carry infection. There are many methods to sterilizing seeds, some more intense than others.

While this is not usually necessary, if you are trying your hardest to avoid disease, this can help mitigate the risk. Note: Sterilization should be done at the time of planting, not during the pepper seed saving process.


We hope this helped you learn how to save pepper seeds for planting next year. Almost nothing is more satisfying than growing a new plant from your very own pepper seeds!

Good luck, and let us know if you have any other recommendations for keeping pepper seeds.

Question for you. We Saved seeds last year from an orange habanero pepper. The plant grown this year, from the saved seeds has red habanero pods instead of the original orange. Curious to know what happened. Thanks for your help

@peppergeek,

Question: When to save seeds and when not do save seeds?

I have different pepper varieties planted within close proximity (Habanero, ghost, cayenne, jalapeño, shishito, sweet banana and others) and for sure they have been crossed pollinated.

If I save these seeds could my habanero be as hot as a ghost pepper? Could my habanero loose its aroma? Could the sweet peppers become spicy?

This can happen if the original variety you grew was a hybrid of some kind. The first round of plants will be highly consistent. Saved seeds from those plants will have very high phenotypic variation - it is basically just how genetics work. So the peppers may taste different, look different, come in different colors, shapes, etc. OR, if your orange plant was next to another pepper type (especially another chinense), it could have been unintentionally cross pollinated.

Thanks for the info. However, I am confused. You state that a pepper shall be ripe e.g. for a jalapeno it should be red, but your photo shows a green jalapeno. Is it OK to use green jalapenos?

It can be, but there is a chance the seeds won't be fully formed and viable. If you have a plant, wait for it to be fully ripe before plucking and harvesting the seeds.

They are calling for a freeze here tonight and I have several bell pepper varieties with no ripened peppers that I want to save. If I bring in some that are green will the pepper and the seeds continue to ripen and be viable? Or should I try to save them from green peppers? They are very large OP varieties just not colored up yet! Thanks

The seeds will likely grow just fine from green peppers, as long as they aren't super under mature. I hope you didn't lose the peppers to the cold!

Can we assume that seeds from a dried pepper will work? thank you

You can try it, however some dried peppers are cooked slightly during dehydration. This may render the seeds unviable. You could try germinating a few now to see if they will be reliable when the time comes to plant next year!
