How to Save Butternut Squash Seeds

Save the seeds from your butternut squash to save money on next year's crop.

If you had a bountiful crop of butternut squash this year and you want to save some seeds to grow next year, it's very simple to do so. It will certainly save you some money. But beware that if you are growing a hybrid variety of butternut squash, the seeds may not produce the exact squash you were growing this year because squash plants are pollinated by insects and cross-pollination may have occurred.

Things You'll Need

• Vegetable peeler
• Sharp knife
• Spoon
• Paper towel
• Envelope
• Airtight jar

Instructions

1. Inspect your butternut squash crop. Be sure that the squash you select to take seeds from has been allowed to grow to full maturity. This will help ensure you will end up with healthy, robust seeds.

2. Peel the outer layer off the squash with a vegetable peeler.

3. Cut the squash from top to bottom down the middle. When you separate it into halves, the seeds will become visible.

4. Scoop out the seeds with a spoon onto a paper towel. Try to take out any chunks of squash that come along with the seeds. Spread them out in a single layer and allow them to dry for three to four days in a cool, dry place. Turn the seeds over every day or two to help them dry.

5. Store the seeds in a paper envelope and place in an airtight jar. Place the jar in the refrigerator or freezer to help maximize shelf life. Your seeds can stay viable for years by doing this.

Tips & Warnings

• Don't wait until next year's planting to see if your seeds are any good. After you have dried them out, take a few and place in the middle of a folded up moist paper towel. Keep the paper towel moist for a few days and wait to see if your seeds germinate. Now you'll know your saved seeds are good ones.
