How to Create a Worm Farm with Kids (Get Your Kids Involved!)

Written by

Creating a worm farm with kids is not only a fun and hands-on way to learn about nature, but it’s also an opportunity to teach them valuable lessons in sustainability and responsibility.

By turning food scraps into nutrient-rich compost, you and your child will experience firsthand how these tiny creatures help the environment.

In this article, I will walk you through every step—from gathering materials to ongoing care.

Get ready to foster curiosity, responsibility, and a deeper understanding of the natural world while having fun together.

Without further ado, let's now get into it!

Gather Your Materials (Let Kids Help!)

Before getting into creating a worm farm, the first step is to gather all the necessary materials. This is a great opportunity to involve your kids in the process.

Not only will it make the task more enjoyable, but it also teaches them about responsibility and planning. Let’s take a look at what you’ll need.

Choosing the Right Container

The container is the foundation of your worm farm. There are several options to choose from, depending on your space, budget, and preference.

You can go with a simple plastic bin or get a bit more creative with a wooden box or a multi-tiered system. Allow your kids to help choose the container—it could be fun for them to pick the color of a plastic bin or even visit a local shop to get a wooden box.

Here are some container ideas to consider:

  • A wooden container is a great choice for a more natural look and is ideal if you're planning on keeping the farm outside. Kids can help decide the size of the box based on the space available in your yard or home.
  • A plastic bin with a lid (around 20-30 cm deep) is another good option. You can even let your kids pick the color of the bin if you’re using a new one. Remember, it’s essential to have a lid to keep the worms in their dark, cool environment.
  • If you have a few old empty buckets (like cat litter containers), these can work as a nesting system. You’ll need at least four buckets, with a lid for the top one to keep the moisture in.
  • Polystyrene boxes are a more eco-friendly option and can often be sourced from local fruit and vegetable shops. You’ll need one box for a simple farm setup, but two for a deluxe model.

Bedding Materials

Now, let’s talk about the bedding material. This is where your kids can really get hands-on. Shredding newspaper, collecting leaves on a nature walk, or cutting up cardboard can all be part of the fun!

The bedding material mimics the worms' natural environment, helping to keep them comfortable while they do their job of composting.

Here are a few bedding materials to gather:

  • Shredded newspaper (black and white is best) forms the base of the bedding. You can have your kids help shred it (just make sure it’s safe and supervised).
  • Cardboard (shredded) works well, too, providing extra carbon for the worms.
  • Coconut coir or peat moss is another good bedding material. It’s often used in gardening and holds moisture well.
  • Dead leaves can be collected on a nature walk and add a nice, natural touch to the bedding.
  • You may also want to mix in some aged compost or manure, which will provide additional nutrients for the worms.

Worms

Of course, you’ll need worms to make the farm work! Red wigglers, also known as Tiger Worms, are the ideal choice for a worm farm.

These worms thrive in composting environments and reproduce quickly, making them perfect for your farm.

You’ll need about 1 kg of worms to get started. You can usually find them at garden centers, bait shops, or online.

It’s important to explain to your kids why these specific worms are ideal – they’re designed for composting and will do the heavy lifting of breaking down food scraps.

Additional Supplies

You’ll also need a few extra items to set up and maintain your worm farm:

  • A drill with a ¼ inch drill bit and safety goggles for creating holes in your container. Be sure to explain safety to your kids, especially if they’re helping or watching.
  • A water spray bottle to keep the bedding moist. Your kids can take charge of this task!
  • Small garden shovels will be useful for moving the bedding or adding new food scraps.
  • A tray to place under the container to catch any excess moisture.
  • Covering materials like old carpet, wet newspaper, or cardboard to keep the farm dark and maintain moisture levels.
  • Mesh or insect screening can be used for lining the bottom of the top box in multi-box systems to prevent worms from falling through.

When you have all your materials gathered, you’ll be ready to move on to setting up your worm farm together!

Set Up the Worm Farm Together

Now that you’ve gathered your materials, it’s time to set up the worm farm. This part of the process is where you can really get your kids involved and let them see how everything comes together.

Whether you’re working with a simple plastic bin or a more elaborate multi-container system, the steps are generally the same. Here’s how to set it all up.

Prepare the Container

The first thing you’ll need to do is prepare your container. This step is crucial because your worms need air circulation and proper drainage to thrive.

If you’re using a wooden container, it’s essential to drill small holes in the bottom and sides to ensure good airflow and prevent water buildup.

Be sure to let your kids help mark where the holes should go, but make sure they’re supervised while drilling.

If you’ve chosen a plastic bin, you’ll need to drill small holes in the lid and sides. These holes provide the necessary ventilation for the worms to breathe. It’s also important to add drainage holes at the bottom to prevent water from accumulating.

If you’re working with a bucket system, drill ¼ inch holes along the bottom of three of the buckets. The fourth bucket will serve as the bottom one, and it should remain solid with no holes.

This setup allows the worms to move freely and ensures proper drainage.

For a polystyrene box system, poke about 10 holes in the base of the main (top) box, using a pencil.

The bottom box will remain solid, but it may have a tap for collecting “worm tea” (liquid produced by the worms).

If you’re using styrofoam fruit boxes, poke holes in the bottom of two boxes (the feeder boxes) and make one small hole in the corner of the third box to catch the worm juice.

Add Bedding

Once your container is ready, it’s time to add the bedding material. This is where you and your kids can really get creative.

Begin by shredding the newspaper and/or cardboard into small pieces. Wet the bedding material with water, then wring it out until it feels like a damp sponge.

Kids can help with the fun, messy part of wetting and wringing!

Layer the moist bedding inside the container, filling it to about a quarter to three-quarters of the way up.

You can mix different types of bedding materials, like shredded newspaper, coir, and peat moss, to create a comfortable environment for your worms.

For a multi-bucket system, place bedding in two of the bins with holes. In a two-box polystyrene system, line the main box with wet newspaper and then add a layer of moistened peat moss.

If you’d like, you can also add some grit and soil to the bedding. This helps the worms with digestion. Mixing in some aged compost or manure can also provide extra nutrients.

Introduce the Worms

Once the bedding is in place, it’s time to introduce the worms!

Gently place the worms on top of the bedding. You’ll likely see them burrow down into the bedding to escape the light, which is a natural reaction. This might take up to a day for all of the worms to settle into their new home.

If you want to make this process extra engaging, you can let the kids “dig up” some red wigglers from a separate container of soil and transfer them carefully to the worm farm.

This gives them a hands-on experience and lets them learn how gentle handling is key when working with living creatures.

Set Up the Environment

Once your worms are in place, it’s important to keep their environment comfortable. Cover the farm with something like an old carpet, wet newspaper, cardboard, or the lid of the container.

This helps maintain darkness, which the worms prefer, and keeps moisture levels stable.

Finally, make sure to place the worm farm in a cool, dark place. A basement, shed, or garage works well, or you can place it in a shady spot outside.

Avoid direct sunlight and extreme temperatures, as these can harm the worms.

Ongoing Care (Kids Can Be Worm Farmers!)

Now that your worm farm is set up, the next step is ensuring that the worms are happy and healthy.

Regular care is essential to keep your farm running smoothly, and this is where your kids can take on more responsibilities.

They’ll learn about consistency, observation, and problem-solving while making sure the farm is well-maintained.

Feeding the Worms

Worms need food, but it’s important not to overfeed them. Overfeeding can cause bad odors and attract pests, so it’s best to introduce food scraps in small amounts and monitor how the worms respond.

Start by waiting a few days before feeding the worms for the first time. This gives them time to settle into their new environment and begin working through the bedding.

Your kids can help collect food scraps such as fruit and vegetable peels, coffee grounds, and eggshells.

Make sure they know that certain foods should never go into the farm, including citrus fruits, onions, garlic, dairy, meat, and oily or spicy foods. These can harm the worms and create unpleasant smells.

Once you have your scraps, cut them into small pieces. This makes it easier for the worms to break them down, as they don’t have teeth.

Bury the food scraps under the bedding to keep things tidy. If you're using a multi-box system, alternate adding food scraps to different boxes, so the worms can move freely through the bedding.

Encourage your kids to check if the worms have eaten all the food scraps before adding more.

If the food hasn’t been fully consumed, wait a little longer before adding more. This helps prevent overfeeding.

Monitoring Moisture Levels (Keep it Just Right)

The moisture level in the worm farm is crucial to the worms' health.

If the bedding gets too dry, the worms may become stressed, and if it’s too wet, the worms can drown. Regularly check the moisture level to ensure it’s just right.

Your kids can help by checking the bedding once a week. The bedding should feel damp, like a wrung-out sponge, but not soggy.

If it feels dry, use a spray bottle to lightly moisten it. This task is easy for kids to take charge of, and they’ll love spraying the bedding!

If you’re using a multi-container system, it’s also important to check for excess moisture in the bottom container.

The worms will produce liquid waste, known as “worm tea,” which is nutrient-rich and can be used as fertilizer. If the liquid builds up too much, it could drown the worms in the top boxes, so make sure to drain it when necessary.

Dealing with Excess Moisture

Excess moisture can lead to problems like mold growth or the farm becoming too smelly.

Teach your kids how to recognize the signs of too much moisture. If they notice a foul odor or if the bedding feels too wet, it's time to address the issue.

In a multi-container system, check if there’s a lot of moisture in the bottom container.

If so, you may need to remove some of the liquid to prevent the worms in the top bins from getting too much water. If you're using a single-bin system, simply add more dry bedding to absorb the excess moisture.

By keeping an eye on the moisture and adjusting as needed, you’ll ensure the worms stay in a comfortable environment and continue their composting work.

Educational Opportunities for Kids

One of the greatest benefits of creating a worm farm with your kids is the educational value. As they care for the worms, they’ll gain a deeper understanding of sustainability, ecosystems, and responsibility.

Here’s how you can turn this activity into a valuable learning experience for your children.

Composting & Recycling

Through worm farming, kids learn about composting and recycling, which are important environmental practices.

They’ll see firsthand how food scraps that would typically be thrown away can be transformed into rich, fertile soil by the worms. This process not only reduces waste but also creates a valuable resource for gardening.

You can talk to your kids about the importance of reducing waste and how composting helps divert organic material from landfills, where it would otherwise contribute to methane gas production.

Explain that by worm farming, they’re playing an active role in sustainability and helping the planet.

Ecosystems & The Role of Worms

Worms are essential members of natural ecosystems. They break down organic matter and enrich the soil with nutrients, which helps plants grow.

This concept can be fascinating for kids, as it shows them how small creatures have a big impact on the world around them.

You can explain to your kids that Charles Darwin called earthworms “the intestines of the soil” because of their critical role in decomposition and nutrient cycling.

As they watch their worms at work, they’ll start to understand how ecosystems function and how every living organism, no matter how small, contributes to the balance of nature.

Sustainability and Responsibility

Worm farming also teaches kids about sustainability. They’ll see how easy it is to create a closed-loop system where food waste is recycled into fertilizer that benefits plants.

This can lead to broader discussions about sustainable practices in everyday life, such as reducing food waste, conserving resources, and supporting eco-friendly products.

Additionally, by caring for the worms, kids will learn about responsibility. They’ll understand the importance of maintaining the farm, feeding the worms properly, and monitoring their environment.

This can build a sense of ownership and pride as they see the farm thriving under their care.

Life Cycles and Worm Anatomy

Teaching kids about the life cycle of worms is another great educational opportunity. Worms start as eggs, hatch into baby worms, and eventually mature into adults.

They also have unique biological features, like multiple hearts and the ability to breathe through their skin.

You can explain to your kids how worms reproduce, and the fascinating fact that they can live for several years in a healthy environment.

Encouraging kids to observe the worms and keep a journal of their findings is an excellent way to engage them with the scientific process and the life cycles of living creatures.

Observation and Science Skills

Finally, worm farming offers an opportunity to develop kids’ scientific observation skills.

Encourage them to regularly check on the worms and note any changes in the bedding, food scraps, or the worms themselves.

Keeping a worm journal where they document their observations, draw pictures, and track the farm’s progress will help them practice critical thinking and record-keeping skills.

By involving your kids in all aspects of worm farming, from setup to ongoing care, you’re not just creating a fun project – you're teaching them essential lessons in science, sustainability, and the natural world.

Troubleshooting Common Worm Farm Problems

Even though worm farming is relatively simple, it’s common to encounter a few challenges along the way. Fortunately, most issues can be easily addressed with a bit of attention and care.

So, I'll walk through some common problems and offer solutions, so you and your kids can keep your farm running smoothly.

Bad Odor

If your worm farm begins to smell, it usually means something is wrong with the environment. Worms thrive in moist, well-ventilated areas, but if the conditions aren’t right, odors can develop.

What Causes the Smell?

The most likely culprit is overfeeding. If you’re adding too much food at once, especially food that hasn’t been properly broken down, it can rot in the bedding, creating foul odors.

Another potential cause is too much moisture in the bin, which leads to anaerobic conditions where harmful bacteria thrive.

How to Fix It

To fix the problem, stop adding food scraps for a few days to give the worms time to catch up. Make sure to only feed them small amounts in the future.

If there’s excess moisture, try adding more bedding (like shredded newspaper) to absorb it. You can also check the ventilation holes to make sure they’re not clogged.

A well-ventilated bin helps prevent foul smells from developing in the first place.

Worms Not Eating Enough

If your worms are not eating the food scraps as quickly as you expect, there could be a few reasons why. It could be because they’re overwhelmed with too much food, or the conditions in the farm might not be ideal.

What Causes the Issue?

Worms can be slow to eat if the bedding is too dry, too wet, or if the food is not broken down enough. Additionally, if you’ve been overfeeding them, they may not be able to process the scraps quickly enough.

How to Fix It

Start by checking the moisture levels. If the bedding is dry, lightly spray it with water to moisten it. If it’s too wet, add more dry bedding to absorb the moisture.

Also, make sure the food scraps are cut into small pieces, which helps worms break them down more easily.

You can also reduce the amount of food you add, giving the worms more time to process what’s already there.

Too Much Liquid (Worm Tea)

Excess liquid, or “worm tea,” can build up in the bottom of your worm farm if the bedding is too wet, or if the farm isn’t draining properly. This can cause a few issues, such as drowning worms or attracting pests.

What Causes the Issue?

Too much liquid usually means the worms have been overfed, or the moisture in the bedding hasn’t been managed properly. In multi-tiered systems, this can happen if one of the layers becomes too moist, leading to liquid pooling below.

How to Fix It

If you have excess liquid, drain it out. You can collect the worm tea and use it as a natural fertilizer for your plants.

To prevent future liquid buildup, monitor the moisture levels more carefully and adjust your feeding habits. If using a multi-tiered system, ensure that each container has enough drainage to prevent water from pooling at the bottom.

Harvesting Worm Castings and Worm Tea

One of the most rewarding aspects of worm farming is the ability to harvest the nutrient-rich products the worms create: worm castings and worm tea.

These are both valuable for gardening, providing natural, organic fertilizer for your plants. Here’s how you can harvest them and use them effectively.

What Are Worm Castings?

Worm Castings are the worm’s waste, but don’t let the term fool you—they are packed with nutrients.

These dark, crumbly castings are rich in essential minerals like nitrogen, phosphorus, and potassium, making them an excellent fertilizer for plants. They also help improve soil structure and promote healthy plant growth.

How to Harvest Worm Castings

To harvest worm castings, you need to separate the worms from the compost. This can be done by using one of the following methods:

Manual Separation

Gently remove the top layers of bedding and castings, exposing the worms. Scoop out the castings and set them aside, making sure to avoid disturbing the worms too much.

You can then add fresh bedding to the container and return the worms to the bottom layer. This method works best if you have a simple worm bin or bucket system.

The Light Method

If you have a multi-tiered system, you can place the castings on top of the bedding and shine a light on them. Worms avoid light, so they’ll naturally move down into the lower layers, allowing you to harvest the castings at the top.

Once you’ve harvested the castings, they’re ready to be used in your garden. Simply mix them into your soil, or sprinkle them around the base of your plants to boost their health and growth.
