How do you teach kids to compost?
Simple. You learn how to do it yourself, then make it part of your daily routine and family culture.
Today I'm sharing these tips on teaching composting to kids at home. And I'm also sharing my newly updated Kids Can Compost Free Printable Pack. You'll find the link to sign up for it down at the bottom of the post.
Composting is a great way to reduce your family's waste, save money, and encourage your children to learn about nature and gardening. You'll turn your food scraps and household organic matter into homemade plant food instead of sending it to a landfill or a dump. You can use it in your raised cinder block garden beds or permaculture garden.

Composting in The Far North

Since we homeschool and homestead off the grid and live a ways from a remote highway in Canada's far north, hauling garbage out to the dump is a pain. So we're always looking for ways to minimize our trash.
And because the soil quality here is poor, (and we've upped our backyard gardening game in a big way) we're learning how to add nutrients to the soil in our raised garden beds. Composting is a big help.
For the past two years, we've been composting indoors through the long winter months. Now that our two youngest are old enough to take on the composting chores, I decided to include composting as part of our off-grid homeschooling routine. (And by the way, here's a great new list of 20 Best Gardening Books for Kids for 2022!)
What is Composting?
Composting is the natural process that occurs when organic matter breaks down into a granular material. This dark, soil-like matter is rich in nutrients and valuable organic fertilizer for your home garden.
Composting requires little to no investment, yet the payoff is huge. It saves money, reduces waste, can help you meet your gardening goals, and is a useful life skill to teach your children.
How to Teach Kids to Compost: 7 Tips to Get You Started
The easiest way to teach kids how to compost at home is to simply include it in your family routine. Do you use printable chore charts? If so, just add a line to include composting chores.
Use these tips to get started.
1. Teach Kids to Identify Compostable Materials
Your compost is only as good as your ingredients. So make sure you and your children know what can and can't be composted. Compostable household materials include:
- Fruit and vegetable scraps
- Eggshells
- Coffee grinds
- Grass clippings
- Leaves, twigs, and branches
- Newspaper
- Coffee filters
2. Teach Kids What NOT To Compost
Once your children know what can get composted, show them what cannot go in the compost. If you add these materials, you'll end up with a slimy, smelly mess. And if you're composting outdoors, you could end up attracting unwanted visitors such as raccoons, neighborhood dogs, foxes, and even bears.
Tip: Post our "Can I Compost This?" printable on your fridge or kitchen wall for easy reference. It's part of our Composting for Kids Printable Pack - link at the bottom of this post.
Materials that should NOT get composted include:
- Meat
- Fat
- Bones
- Cheese
- Milk
- Oils
- Pet poop
- Diseased plants or flowers
Even children as young as three or four years old can learn to identify what is compostable and what isn't.
3. Countertop Composting is Easy
Make it easy for your kids to compost with a clearly identified compost container. Buy or make an indoor compost bin or pail.
Some people prefer a foot-pedal style kitchen garbage-can system. You'll find them in your local hardware store or even online. Some models have three containers: one for trash, one for recyclables, and one for compost.
I loved the idea of this, but so did our yellow Lab Leo. As far as he's concerned, a floor-level compost bin is a bonus food bowl for him. So we decided to go with a countertop compost system.
At first, we had a stainless steel counter compost pail, but the charcoal filter didn't seem to do much to keep the smell down. And it was annoying to have to replace them. Plus, it was difficult for little hands to lift the heavy lid.
Since we're always trying to find ways to save money, we moved to a coffee can compost system. We just have a large coffee can on the counter right across from our kitchen garbage.

4. Make it Part of Your Daily Routine
As with most life schooling opportunities for kids, making composting a part of their daily routine from an early age is key to success. They'll soon get the hang of putting apple cores, banana peels, vegetable scraps, and eggshells into the compost before doing their dishes (hah!)
Related: Using Foraging to Teach
In our home, compostable scraps go into the coffee can on the kitchen counter. When it gets full, the kids dump it into our indoor compost bin (in the winter) or our outdoor compost bin (in the summer.)
5. Schedule Weekly Composting Activity and Learning Opportunities
Depending on where you live, you might get a deal on an outdoor composter.
In some parts of Canada, residents can take proof of residence to their local municipal office or waste disposal area and get a free or discounted outdoor composter.
These easy-to-use big bins let you add your kitchen compost and yard waste to the top. As the compost "cooks" inside, it eventually turns into dark, soil-like material you can access through a little door at the bottom.
When you're teaching your kids to compost, schedule weekly composting activities as a regular family chore you can all work on together. Depending on the state of your compost, this could be turning hot compost with a shovel, adding worms, or spreading it in the garden.
In addition to hands-on learning and lessons, composting also gives you an opportunity for many academic lessons. Depending on the age of your children, you could read picture books on composting, watch videos, complete unit studies, or do a science experiment.
Scroll down the page for a list of free online resources to help kids learn about composting.
6. Fun With Worms: Vermicomposting With Kids
Let's face it - fruit and vegetable scraps and coffee grounds might not appeal to all kids - or even all adults! When the "thrill" (and I use the term loosely) of composting wore off on our kids, my husband had a brainwave. It was time for worms.
One of our homeschooling friends gave us a tin of red wiggler worms. We released them into our indoor Rubbermaid compost bin and began our adventures with vermicomposting.
It sits in our water tank room during the winter. Unless you live off the grid and pump your own water from the lake behind your house the way we do, chances are you don't have a water tank room. That's perfectly fine - just keep your compost bin in a room-temperature environment out of the reach of pets.
Adding red wiggler worms helped keep the odor down in our indoor compost bin. According to Red Wiggler Supply down in Vancouver, BC., one pound of red wiggler worms consume up to ½ pound of food scraps...per day!
7. Use Compost in Your Garden Containers and Beds
Once your compost is ready to use, it's time to put it to use. Gather it in a pail, bin, or basket, and spread it in the garden with a small trowel. Work it into the soil.
If you don't have space for garden beds, start a container garden. This is a good way to introduce gardening to your children.

Hi there, love the poster for kids to se what to and not to compost.
i cant see link. Is it broken or removed? clocking images does not provide me a link.
Sarita Harbour
Hi Mary Leigh! Thanks for your comment. So we don't compost vegetables that have been cooked with dairy products because it seems to make the compost slimy. And we don't mind if the veggies or fruits sprout - they just get turned over in our garden anyways!
Mary Leigh
Thanks so much for this! Are there any fruit/veggies to not compost? What about seeds? How to keep them from sprouting?

Thanks for the comment Alli - and I love this! Good for you! Our compost has been instrumental in growing a bumper crop of potatoes this year so we're continuing on - and now we have chicken manure to add to it as well. 🙂

I have stumbled across your site & of course I had to check out your compost post. One other option for a container to compost in, that I discovered by accident, is to use a livestock water trough.
I have a 100 gallon trough that my mom used for strawberries, since it had drain holes & I need someplace to put some stuff, I figured what the heck. So, I initially lined the bottom (& some of the sides) with old pizza boxes & the cardboard from store bought pizza & then i had some paper that I put in too. I needed something to cover up the drain holes (one was very big) & then I started to add grass, kitchen scrap's, pine needles & cone's, etc. And just kept doing it until I filled it up completely & then left it alone through the winter (forgot about it). We did add kitchen scrap's, but when the kids did it, they just put it on top, so the chicken's usually ate it. I started "turning" it this spring & tossed a few earth worms in over the early summer when we got some come up. But even after it's been mainly ignored, it's produced some great soil. Same thing with a "pile" that I created 2 years ago, I haven't been able to use the dirt/soil from that as the kids keep adding to it where it was finished LOL.

I cannot find the pack to print. I understand it was part of the resourse library, but I couldn't seem to find just that pack.
Sarita Harbour
Hi Laura! I'll email you directly as well, (and I'm changing the wording to make it more clear). The pack is part of our resource library, which you can sign up for in the green box at the bottom of the post. 🙂

Two things, I think I missed the password for getting the downloadable compost printables. I run International Compost Awareness Week (ICAW) and I thought this packet might be something we would want to add to our website, if that is okay. Can you let me know what the password is and if it's okay to share? Also, with ICAW, we have a poster contest every year to kick off ICAW. For ICAW 2020, the contest starts Sept. 1st. The winning design is used for the ICAW 2020 poster. It's a fun contest and is a good way to educate children about compost (and adults). It's open to anyone age 10 and up to enter. I thought this might be something you may want to share.
Thank you,
Beth Simone

I like composting. It took 3 or 4 years for me to convince my Mr. Menace to do it too though. I had to keep dragging stuff out of the trash. He finally took pity on me and now puts it in my compost containers for me to take outside to the pile.

Great article! I have a vermicomposter in my upstairs plant room and it's even fun for me! I never thought about using composting as a homeschool activity for kids. I think I'm going to come live with you and pretend to be your kid, their school life sounds a lot more fun than mine ever was!
Linda Carlson
I love seeing anything that will get kids out in nature and doing more outside plus learning. I believe the local grade school was doing some composting last year.

Worm farms are so much fun! And they double as fish bait. Great post, I love teaching my kids about the world in hands on messy ways!
