Growing your own pumpkins is a fun and rewarding way to get into the fall spirit. But did you know you can save the seeds from your harvest and plant them again next year? Not only is this an economical way to grow your favorite pumpkins year after year, but it’s also a great step towards more sustainable gardening. The process is simple! You need to remove the seeds, clean them, and store them properly so they’re ready for planting when the next season rolls around.
Plus, saving your seeds means you’ll have a personal connection to each pumpkin that grows in your garden next year. In this guide, we’ll walk you through everything you need to know about harvesting and storing your pumpkin seeds so you can enjoy your homegrown pumpkins.
Benefits of Saving Pumpkin Seeds
Saving pumpkin seeds is not only easy, but it can also be incredibly rewarding! One of the biggest perks is that it saves you money—you won’t need to buy new seeds for next year’s planting. If you have a favorite variety of pumpkins, saving those seeds ensures you can grow them again next season. By preserving your seeds, especially heirloom or rare varieties, you’re helping promote biodiversity in your garden. This keeps those unique pumpkins thriving, even when they might be hard to find locally.
And let’s be honest—there’s something deeply satisfying about growing plants from seeds you’ve personally saved. It gives your gardening efforts a full-circle feeling!
Types of Pumpkins for Seed Saving
When saving pumpkin seeds, choosing the right type of pumpkin is key. Heirloom and open-pollinated varieties are your best bet. Heirloom pumpkins passed down through generations are known for their distinct traits and make excellent candidates for seed saving. Open-pollinated pumpkins are also a great choice because they tend to breed true to their parent plant. This means the pumpkins you grow next season will likely look and taste just like the ones you harvested seeds from.
However, it is best to avoid saving seeds from hybrid or cross-pollinated pumpkins. These pumpkins are less reliable when reproducing the same traits, so the results next year may not be what you expect. Stick with heirloom and open-pollinated varieties for the best seed-saving success!
Step 1: Choose the Right Pumpkin
Select a healthy, mature pumpkin with fully ripened seeds, and avoid any pumpkins that show signs of disease or rot, as these could affect the quality of the seeds you save. Using the seeds from your Halloween pumpkin carving project is a great idea!
Step 2: Remove Seeds From Pumpkin
Place the pumpkin on a steady surface and carefully cut a circle around the stem with a sharp knife, creating an opening large enough for you to scoop out the seeds. Once the pumpkin is open, use a large spoon or your hands to remove the seeds and pulp. Be sure to scrape the inner walls to collect all the seeds. It’s normal for the seeds to be mixed with pulp at this stage.
Step 3: Soak the Seeds in Water
Place the mixture into a large bowl or container filled with water to separate the seeds from the pulp. Using your hands, gently work through the mixture, allowing the viable seeds to sink to the bottom. The pulp and any nonviable seeds will float to the top, making it easy to discard them. Once you’ve removed the debris, rinse the remaining seeds thoroughly with clean water to prepare them for drying and storing.
Step 4: Rinse the Pumpkin Seeds
Once you've separated the seeds, place them in a colander or sieve and rinse them under cold water to remove any remaining pulp. Next, you'll need to wash and dry the seeds thoroughly. Start by filling a bowl with water and adding the seeds. Swirl them gently in the water to remove any remaining pulp, which should float to the surface. You may need to repeat this process until the seeds are clean and pulp-free.
Step 5: Dry the Pumpkin Seeds
After washing, it’s important to dry the seeds properly before storing them. Spread the seeds in a single layer on a clean towel or paper towel and allow them to air dry for several hours or even overnight. Ensure they are completely dry before storing them to prevent mold or decay.
Storing Pumpkin Seeds
To ensure your pumpkin seeds remain viable for planting next year, store them under the right conditions. First, make sure the seeds are thoroughly dry before placing them in storage. The ideal storage environment is cool, dry, and dark, with a temperature between 35°F and 40°F and a humidity level of around 40%. This helps prevent fungal or bacterial growth and reduces the risk of the seeds germinating too early.
Choose The Right Container
There are a few great options when choosing a container for your seeds. Glass jars with tight-fitting lids are a reliable choice, as they prevent moisture from getting in and can be easily sealed. Just be sure to label the jar with the seed type and date of storage. Plastic containers also work well, especially food-safe ones with tight lids. As with glass jars, ensure the container is clean and dry, and don’t forget to label it.
Or Store In An Envelope
Another cost-effective option is to store your seeds in envelopes or paper bags. These allow air to circulate while keeping them organized. For extra protection, you can place the envelope or paper bag inside a lidded plastic or glass container. Regardless of your chosen container, always store your seeds in a cool, dry, and dark place. Make sure everything is clearly labeled to keep your seeds viable for the next season.

Common Mistakes and How to Avoid Them
One common mistake when saving pumpkin seeds is inadequate drying. Once cleaned, the seeds must be thoroughly dried to prevent mold and ensure they last in storage. Also, not labeling your seeds can lead to confusion, especially if you're saving seeds from multiple varieties. Avoid this by clearly labeling each container or envelope with the pumpkin variety name and the date the seeds were saved. This will save you time and confusion when it’s time to plant next year.
