starting containers. (In fact, they are my favorite!)
2. Cookie, donuts, and other sweet containers. The kind that are plastic with a lid. Again, these are ideal for seed sowing.
3. Toilet paper and paper towel tubes. If you fold the ends under, they make perfect little pots that are biodegradable. (Learn how to make these pots in my free ebook Starting Seeds.)
4. Newspaper. It's easy to fold these into individual seed starting pots. (Learn how my free ebook Starting Seeds.)
5. Plastic soda pop and water jars. Just cut off the tops of plastic jars to make them a suitable height. If you like, duct tape the tops back on, to make a mini greenhouse.
6. Milk and juice jugs and cartons. Treat the plastic jugs just like soda jars. Cut cartons down to height -

7. Yogurt tubs. Also tubs from cottage cheese, Cool Whip, ricotta cheese, and so on.
8. Aluminum soda pop and beer cans. These can be tricky to cut in half (Use caution! The cut edges will be sharp!), but they do work as nice little seed pots.
9. Styrofoam, plastic, and wax-coated paper disposable cups. The kind with domed plastic lids are perfect for making little greenhouses, but even lid-less types work.
10. Aluminum cans from canned food.
11. Aluminum roasting pans. Cheap ones from the Dollar Tree are just fine - or, if you buy rotisserie chicken, the pans they come in work great, too. Ideally, use the type with clear plastic lids.
12. Coffee cans.

14. Chinese takeout boxes.
15. Plastic or Styrofoam takeout boxes.
16. Old Tupperware-style containers.
17. Cereal boxes. Just cut down their height.
And a few containers I don't recommend:
* Egg cartons. They aren't deep enough for seedlings to develop healthy roots.
* Ice cube trays. Again, unless they are unusually deep, the seedlings won't develop good root systems.
* Egg shells. Again, the problem is no room for roots.
* Citrus halves. No room for roots!
* Plastic berry boxes. These may seem ideal, but they have holes all over them, and this defeats the wonderful mini greenhouses effect of boxes with lids. If you have plastic berry boxes, go ahead and use them, but plan on using something else to create a greenhouse effect
* Glass jars. All seed starting containers need to have drainage holes...and you can't put drainage holes in glass.
How to Use Upcycled Materials for Seed Starting Pots:
1. Make sure the container has good drainage. Unless the container is paper (like a toilet paper tube), that means poking some holes in the bottom. At least 3 will work for a very small container, like a yogurt cup. For larger containers, like a salad greens box, use 5 - 8. If the material of the container is thin, you may be able to carefully poke drainage holes using one blade of a pair of scissors. Be careful! And make sure you're creating a hole, not just a slit. Otherwise, I recommend using either a hammer and fat nail or an electric drill.
2. Make sure the container is clean.
3. Add new soil - not soil from the garden and not soil that's been used before (unless you know how to sterilze old potting soil). You can use soil designed just for seed starting, but I have great success using plain old potting soil.
4. Thoroughly dampen the soil. Make sure it's wet all the way to the bottom of the container.
5. Plant the seeds, according to seed packet directions.
You can now leave the containers as is, but you'll have better success if you create mini greenhouses that hold in moisture and heat:
6. If the container came with a clear plastic lid, make a few slits in the lid carefully using a pair of scissors or Exacto knife. Place the lid securely on top of the container. Within a few minutes, the container should fog up. If it doesn't, either the lid isn't a tight enough fit or the soil is too dry. As the seedlings grow, gradually cut away more and more of the lid until the plant is ready to go into the garden.
7. If the container has no lid, you can still create a greenhouse effect by putting a plastic Ziplock-style bag
over the top of the container, open end down. (Stiff freezer bags are easiest to use; if the bag wants to sag and not stand upright, place a few sticks in the seed pot to hold the plastic up.)
8. If you have many small seed pots (for example, toilet paper tube pots), you can put them in a plastic tub, old Tupperware-style container, roasting pan, or a plastic greens box from the gocery store. Make sure the larger container has some drainage holes and use the container lid (with air circulation slits) to cover the seedlings. Or, cover the large container with plastic wrap, loosely placed on top.
