What Is Paper Towel Germination?
Paper towel germination is an easy way to speed up seed sprouting! It’s so easy that I can’t believe I haven’t been doing it all along.
Simply keep seeds consistently moist by wrapping them in damp paper towels and sealing them up in plastic baggies for the greenhouse effect.
I can’t resist checking my plastic bag greenhouses the next morning and throughout the day! Some seeds like peas will often germinate overnight!
What Are the Benefits of Paper Towel Germination?
I can’t say enough great things about starting seeds in wet paper towels! Here are some of the best benefits of seed germination in plastic baggies with moist paper towel:
- Quicker Germination – Seeds can sprout overnight or within just a few days! (Some varieties take longer, but the overall process is definitely quicker!)
- Less Mess – Starting seeds in plastic baggies with wet paper towels means no need to mess around with potting soil for a little while at first. Enjoy the cleaner and quicker start to your garden!
- Seed Viability Testing – The paper towel method makes it so easy to check the germination rate and viability of your seeds. This is particularly helpful when you have limited gardening space at your disposal!
- Small Space Friendly – If your indoor gardening setup is limited, you can still enjoy bountiful seed starting.
- So Much Fun – With a gardening activity like growing seeds in a plastic bag, preschool kids, toddlers, school aged kids – heck, just about anyone will enjoy the discovery and adventure of this fun process. Germination for kids at its finest!

Germinating Seeds in Paper Towel and Plastic Bag Method: How To
The method of germinating seeds in paper towels is so easy! I am really excited to guide you through this experience. It’s my favorite fast germination gardening technique.
Here’s how to germinate seeds in paper towels:
- Place a half-size paper towel on your work surface or tear a full-size sheet in half.
- Use a spray bottle filled with tap water to moisten the paper towel.
- Space out the seeds you wish to germinate at least an inch apart, if possible.
- Lightly sprits the paper towel one last time to wet the seeds as well.
- Fold the towel to wrap it around the seeds.
- Place the folded paper towel with seeds inside the bag and leave a little air inside if desired.
- Seal the Ziploc baggie and place it somewhere warm!
Tip: For the most part, I place them out of direct sunlight and often more in the dark.
Where to Put Seeds Germinating in Paper Towels and Bags?
I find a little bit of heat speeds up most of the seeds I try to grow in this manner.
You can place them most anywhere that’s warm! On top of your microwave or fridge is a great starting point. You could also try near the dryer or somewhere else that gets warm.
(Just be sure not to create a fire hazard!)
I like to place mine on the floor surrounding our heating vents!
Last year I had them in the kitchen, powder room, and dining room. It may or may not have driven my husband absolutely nuts. (Sorry babe!)
It was AWESOME!
Can’t wait to do it again… Every. Single. Year.
What Seeds to Start in Wet Paper Towels and Baggies?
I am so excited about this process that I will probably start most of my seeds in wet paper towels forever.
Last year I tried SO many different kinds of seeds in paper towels. We germinated all of these seeds using the wet paper towel method:
- Snow Peas
- Green Beans
- Wax Beans
- Mixed Beans from a soup mix
I am sure there were many others since I loved this method and kept trying it. Betting my bottom dollar there will be many more, too!
I haven’t tried it, but I’ve heard you can use paper towel germination techniques on lavender, papaya, cactus, and poppy seeds.
Worth a shot!
When sprouting seeds, paper towels moistened with water can often coax even the most stubborn seedlings out!
If you try any, hit us up in the comments and let us know how it goes, please!
Also, it’s worth noting that not all crops are best suited for paper towel germination. For example, kale germination time is very quick! You wouldn’t gain much by starting kale in wet paper towels. Meanwhile, a number of cool weather crops and some delicate flowers sometimes work better direct sown.
My very first experience with wet paper towel seed germination was with peas. And it was every bit of amazing.
I am not kidding you – they literally had their little root radicle popping out the very next morning when I checked them! Most of the seeds germinated overnight!
Germinating Tomato Seeds in Paper Towel
I’m not going to lie. I got tired of waiting for my tomato seeds to germinate last season.
First, I had to find and buy Roma seeds! It felt like they were sold out everywhere (stupid pandemic!!).
Then, I ordered them and they took the better part of a week to get here!
A week is major when you wanna start a garden!
Finally, they arrived and I planted them immediately. Like, right after I opened the mailing envelope.
Waited some more…
You get the idea!
Finally, I got tired of waiting so I decided to try the paper towel germination method that had worked so well with our pea seedlings.
I can’t remember how long it took, but germinating tomato seeds in paper towels was way quicker than starting seeds in dirt. Planting directly in potting soil took more than 12 days if my memory serves me.
Probably closer to two weeks, but I was very impatient if I’m being honest.
Even under lights!
Needless to say, I will be germinating tomato seeds in paper towel and baggy method for the foreseeable future. 🙂
Germinating Eggplant Seeds with Paper Towel
I couldn’t get my eggplant seeds to sprout at all in traditional potting soil! Did anyone else have trouble?
I decided to try starting seeds in paper towel soaked in water in a zip-seal baggie for my eggplants this year.
Voila! Just like magic, I got excellent results germinating eggplant seeds using the wet paper towel method.
Once established, the tiny eggplant seedlings transferred very well to egg cartons with potting soil.
The eggplant seedlings also potted up well to bigger pots and grew to maturity outside.
I love that they self-pollinate! It was so exciting to see the bright purple blossom and then the purple fruit growing.
Waiting for the eggplant to grow larger, I gave the roving groundhog ample opportunity to steal it.
And steal it he did!
We were so disappointed because we still could’ve picked the eggplant small. That groundhog is the worst!
Hoping for better luck next year!
Germinating Strawberry Seeds (Paper Towel Method)
I have not tried germinating strawberry seeds in paper towels yet, but I fully believe it will work.
Last year we grew baby strawberry plants from seed in little Dixie cups on my kitchen windowsill. They did AMAZING!
Superb germination rate and adorable little plants. The worst part was they took every moment of three weeks to germinate.
I did constant water misting at least once per day, so I have full confidence they will do well with paper towel germination.
This sounds like a good gardening starter project to help chase away the winter blues!
(By the way, if you’d like to try my method, check out my other post – Planting Strawberry Seeds in Pots.
Germinating Apple Seeds in Paper Towel
Planting apple seeds is a little controversial in some of my gardening groups. It’s well-known or at least widely suggested that apple trees grown from seed do not grow true to type.
So, they may not at all resemble the parent plant.
In other worse, you may end up with a crabapple!
Or worse, no fruit at all.
Still, I am a curious gardener and love the growing process. I have heard success stories of those who’ve planted from seed.
I’ve heard grafting is the commonly used process, but I always think it’s good to give it the old college try.
Last year we found some Granny Smith apple seeds that had sprouted inside the apple! We happily harvested them and transferred some to soil and some to baggies with wet paper towels.
All of them did really well!
Unfortunately, they did not get all the care needed once we moved them outside, and some got roasted before being hardened off. It breaks my heart thinking about it, actually.
Better luck next time and at least we have a pear tree growing that we started with this very same germination method!
I can’t recall if it’s a Bartlett or D’Anjou, but the way my kids devour pears, I am going to pray whatever it is decides to bear fruit in a few years!
Tips for Sprouting Seeds in Paper Towel
Here are some of my best tips for sprouting seeds in paper towels:
- Write the date and seed type on the baggie. I use a Sharpie for this. I get so excited gardening, I often go overboard, so it’s good to know what’s what and when you first planted them!
- Plant those with the longest time to germination first. I found the paper towel / plastic baggie method very helpful in speeding up germination for peppers, tomatoes, and eggplant especially.
- Don’t be discouraged if the seeds won’t germinate right away. You can check out my troubleshooting steps below for a better result!
- Use a gardening journal to track your efforts and results! I like to think I would remember everything but as a mom of two girls, I know it just isn’t true. I am definitely planning to start a garden journal this year to track our start dates, sprout dates, harvests, successes, and what to do different the following years!
- Space it out so you have more nights to enjoy it! It’s quick and easy to pop a few more seeds inside a wet paper towel and seal it up. Give yourself something fun to look forward to at the end of each day. Do it before bed so you get all the time while you’re sleeping for those babies to grow, grow, grow!

Troubleshooting: Why Are My Seeds Not Germinating in Paper Towel Method?
Waiting for seeds to sprout takes a lot of patience! Sometimes I just don’t have it in me.
I find starting seeds in a paper towel inside baggies will give me an awesome head start!
Still, I may find some seeds not germinating in paper towel method, despite my best efforts.
Here are some troubleshooting steps to try as you begin starting seeds in paper towels.
- Is your paper towel too wet? Seeds can start to rot if there’s too much water and they’ve taken too long to germinate.
- Is your paper towel too dry? Your seeds may need constant moisture to sprout.
- Does your particular type of seed need sunlight to germinate? Try taping a baggie of seeds in a wet paper towel on a window or glass door!
- Are your seeds too old or otherwise unviable? If you’ve got a bad batch of seeds or a particularly old batch, they may not sprout no matter what you do. Try adding some heat! You can place your seed baggies on top of your fridge, microwave, or next to your heating vent on the floor.
- Does your seed need cold stratification? Try placing your baggies in the fridge for a week or two and check them again after they’ve had some time to chill out!
