Just in time for Halloween, let’s cover how to save pumpkin seeds.
Learning how to save pumpkin seeds is a good idea, especially if you’d like to grow next year’s jack-o-lanterns yourself.
I’ve been growing pumpkin and winter squash for a long time and I’ve always loved how easy it is to save pumpkin seeds.
Recently I posted a new video on how I save pumpkin seeds – and how I make seed packets to hold them until it’s time to plant them in the spring.
Here’s the video:
Now let’s break it down into a nice visual guide with pictures and everything!
How To Save Pumpkin Seeds, Step by Step
Are you ready to pack away seeds like a kleptomaniac squirrel so you never have to buy another pumpkin from the store again? I will help.
Step 1: Gut the Pumpkin and Save the Slop!
The inner cavity of pumpkins and winter squashes is filled with a stringy mess of pumpkin bits and seeds. This isn’t the “good eating” part of the pumpkin, so it’s not worth trying to save any of the stringy mass, except for the seeds. In order to do that, move on to step two!
Step 2: Clean the Pumpkin Seeds
I dump pumpkin guts and seeds into a colander and swish them around under running water to clean them out, smashing the goop through the holes and separating the strings. If you’d like to save pumpkin seeds for eating rather than planting, you can just go directly to roasting them at this point.
For seed-saving purposes, I’ve sometimes let pumpkin guts sit on the counter for a few days and rot around the seeds. This smells bad but really loosens up the seeds when you wash them out. I think it may also increase the germination rate but I haven’t tried a side-by-side trial.
Step 3: Dry The Seeds
Seed-covered paper towels on counters, windowsills, shelves, tabletops, dressers and even the bathroom counter are common in our house during the fall as we save pumpkin seeds alongside the other heirlooms we want to plant in our spring gardens.
Spread your pumpkin seeds out someplace where they won’t get wet again. Make sure they aren’t too wet when you spread them out (sometimes I pat them down with one paper towel, then spread them onto a second) and have good air circulation as you most definitely do not want them germinating on your counter. They should dry fast. This will also keep them from molding as easily in storage and potentially losing their ability to germinate.
Step 4: Make Seed Packets and Pack ’em Up!
There are better ways to make seed packets, but I just rip a sheet of paper in half, fold that, then fold up the edges a few times and tape them. You can see how in the video – it’s very simple.
Because I’m cheap and hate throwing things away too fast, I use scrap paper from the children’s homeschool assignments or pieces the toddler has doodled upon. My friend Steven Edholm has better looking seed packets, but they’re a bit small for the amount of pumpkin seeds I store.
I also illustrate my homemade seed packets, which is NOT OPTIONAL. You have to draw on them. You just have to. It’s the rule.
Along with a drawing of the mother pumpkin, I also note the variety, the harvest year and notes on type. This is important as I work on my pumpkin breeding projects, but for your pumpkin seed saving you likely just need to note the type or draw a nice picture of the headless horseman.
If you live in a humid climate or need to store seeds for a longer period, you can dry pumpkin seeds a little further in a dehydrator (I like this reliable and inexpensive one for everything from fruit to jerky) and then pack them in tightly shut Mason jars stowed in the fridge.
That’s it – the whole scoop on how to save pumpkin seeds.
If you’re interested in going much deeper into saving seeds of all kinds, Seed to Seed is my own go-to resource on the subject. It’s a must-have for serious gardeners.
Happy gardening and enjoy the rest of October.
