How to Store Squash Seeds


Squash plants, such as summer squash and pumpkins, are relatively low maintenance and make a great addition to a backyard vegetable garden. Some gardeners harvest seeds from their ripe squash so they do not have to buy new seeds at the start of every year. Store your squash seeds properly to protect their viability so you can keep planting squash for many years to come.

Step 1

Remove the seeds from the squash. Rinse under fresh water to clean the seeds from any clinging pieces of squash flesh.

Step 2

Place the seeds on newspaper and allow them to dry at room temperature for four to five days. You can hasten the drying process by aiming a room fan at the seeds.

Step 3

Pour 1/2 a cup of flour, dried milk or baking soda into a cloth bag. Tie the bag shut and drop it into a jar with a lid. This helps absorb any moisture that may still be on the seeds or in the jar.

Step 4

Empty the dried squash seeds into the jar. Close the cover tightly and put the jar in your refrigerator. Squash seeds can stay viable for up to five years, according to the Oregon State University.

Tips and Warnings

  • Don't collect seeds from hybrid squash varieties. These seeds will not germinate true, meaning the resulting seedlings will likely be very different from the squash plant from which you collected them.
