Seed starting is a fun way to grow the plants you really want to grow that you can’t always find at the greenhouse, but it’s frustrating having to use so much flimsy plastic. Sure, you can use recycled plastic containers to cut down on waste, but did you know there’s a way to make recycled pots out of newsprint?
Bonus, you can just pop them in the ground when it’s time to plant and you don’t have to disturb the roots.
So stop using those egg cartons for seed starting (trust me, it’s highly overrated!!) and I’ll show you how easy it is to make paper seed starting pots.
If you prefer to watch a video, here’s exactly how I made mine below. I’ll provide written instructions in the rest of the post.
How to Plant Seeds in Paper Cups
To make paper seed starting cups, you’ll need the following supplies:
- Tall circular items to use as molds
- Optional: One of these fancy seed pot makers
- Potting soil
Cut the newspaper into strips that are the height of your container, plus and inch or two more. You’ll need to allow enough space at the end to fold in the newspaper and create the bottom of the pot.
Make sure the strips of paper are long enough to roll around your mold at least twice, if not three times.
Roll the newsprint strip around the mold, leaving space at one end to fold in at the bottom. Fold in to create the bottom of the pot. Remove the paper from the mold. Fill with potting soil and add your seed.
Put your new newspaper seedling pots in a waterproof container, and water from the bottom. It may take a few hours for the water to soak through, but it’s much better for your new seed-babies.

What are good items for a paper pot mold?
I like to use small jars, cups that are straight at the sides, wine bottles, or empty pop cans. Any circular item will do, as long as the sides are straight and it’s the diameter you want.
I recommend using a larger diameter the further in advance you need to start the seed. For example, you don’t want to use a toilet paper roll size for a tomato plant that you start 8 weeks in advance. Your tomato plant will quickly outgrow the small size and you’ll just have to do it again or make a bigger pot for it.
If you don’t want to hunt for the perfect sized container, you can always buy one of these seed pot maker kits.
Can you Plant a newsprint pot into the ground?
Yes! That is the whole point of making these pots. If you’re nervous, you can loosen the bottom a bit before you put your plant into it’s spot in the garden.
Will the recyclable seed pots actually last until it’s time to plant my garden?
They may not look pretty, but yes. Keep watering your plants from the bottom and let the water soak up for the best results.
