Bean Sprout Gardening – A Fun Activity for Kids

Growing bean sprouts at home is an easy and enjoyable gardening project for children and families. Kids will have fun observing the sprouts develop and will be excited to eat the results of their efforts!

Materials Needed

To get started, you’ll need a few basic supplies:

  • Clean jar (a mason jar or reused glass jar works well)
  • Bean sprout seeds (mung beans or soybeans are common)
  • Cheesecloth or muslin
  • Water


  1. Select and rinse the beans. Measure out 1-2 tablespoons of beans per jar. Rinse thoroughly in a colander to remove any dirt or debris.
  2. Soak the beans overnight. Place the rinsed beans in a jar and cover with water. Let soak for 8-12 hours. The beans will expand as they soak, so don’t overfill the jar.
  3. Prepare the jar. Remove the beans and place a piece of cheesecloth or muslin over the mouth of the jar, securing it with a rubber band or string. Add the soaked beans to the jar, filling no more than a third of the space.
  4. Place in a dim spot. Put the jar in a cupboard away from direct light. Let the beans soak for another 8-12 hours until they sprout little tails. Rinse and drain them twice a day.
  5. Harvest the sprouts. Once the sprouts are 1-2 inches long, usually 3 to 5 days, they’re ready to eat! Rinse and enjoy them in salads, sandwiches, and stir fries. Handle gently since sprouts are delicate.

Growing bean sprouts is a fun, hands-on project for kids and families. In just a few days, you’ll have a jar full of crunchy, nutritious sprouts to add to your meals. Enjoy your homegrown sprouts and the satisfaction of producing your own healthy food.

What You’ll Need – Beans, Jars, Cheesecloth

To get started growing your own bean sprouts, you’ll need a few basic supplies. The good news is that you likely already have most of these in your kitchen!


Select beans that sprout well, such as mung beans, lentils, alfalfa, radish or broccoli seeds. For beginners, mung beans and lentils are easy to sprout and versatile in recipes. Rinse the beans thoroughly to remove any dirt or debris.


You’ll want a jar with a wide mouth, like a mason jar or an old spaghetti sauce jar. Make sure it’s thoroughly cleaned and rinsed. The jar should be transparent so you can keep an eye on your sprouts as they grow.

Cheesecloth or Muslin

You’ll need something to cover the mouth of the jar to allow for air circulation while keeping out dust. Cheesecloth, muslin or a reusable nut milk bag are inexpensive options. Secure the covering over the jar mouth with an elastic band or jar ring.


Use clean, room temperature water to soak and rinse your beans during the sprouting process. Change the water at least twice a day to prevent the growth of bacteria.

That’s really all you need to get started. Find a spot out of direct sunlight, like a cupboard or pantry, to place your jar. Rinse and drain the beans a few times a day, and in 3 to 5 days you’ll have a jar full of crunchy, nourishing bean sprouts. Enjoy them in salads, sandwiches, stir fries or straight from the jar! With such a simple set-up, you’ll be harvesting homegrown sprouts in no time.

Step-by-Step Guide to Planting Bean Sprouts

Selecting the Beans

The first step is choosing what type of bean sprouts you want to grow. The most common options are mung beans or soybeans. These are inexpensive, sprout quickly and have a mild flavour. Once you’ve selected your beans, measure out about 1⁄4 to 1⁄2 cup, depending on how many sprouts you want. Remember, the beans will double in volume as they sprout.

Rinsing and Soaking

Rinse the beans thoroughly in a colander to remove any dirt or debris. Then place them in a bowl and cover with water. Let the beans soak overnight, about 12 hours. The soaking process helps soften the outer coat of the beans, allowing them to sprout more easily.

Preparing the Jar

After soaking, drain the beans and transfer them to a wide-mouth glass jar, like a mason jar. Fill the jar with fresh water, making sure the beans take up no more than 1⁄3 of the jar. Cover the opening with muslin, cheesecloth or a mesh sprouter lid. This allows for air flow while keeping contaminants out.

Draining and Rinsing

Place the jar in a dim area away from direct sunlight. Over the next couple of days, rinse and drain the beans 2-3 times a day. Fill the jar with fresh water and drain completely. Repeat this until you see sprouts start to form, usually in 3 to 5 days. The sprouts are ready once they reach 1 to 2 inches in length.

Harvesting Your Sprouts

Once the sprouts have reached the desired length, they’re ready to harvest! Gently lift out the sprouts and rinse them one final time. Enjoy your sprouts immediately, as they only last 2 to 3 days. Add them to salads, sandwiches, stir fries or eat them on their own. Homegrown sprouts are fresher and more nutritious than store-bought, so savour their crunchy goodness!

Growing your own bean sprouts is a simple process that yields a bounty of nutritious microgreens. In just a few days, you’ll have a steady supply of sprouts to boost your meals. Happy sprouting!

Caring for Your Bean Sprouts

Keep Them Hydrated

Bean sprouts need to stay moist, so make sure you rinse them at least twice a day. Gently swish them around in fresh water to remove any dirt or debris. Then drain them thoroughly in a colander. Never leave them sitting in standing water, as this can cause them to rot.

Provide Good Air Circulation

Bean sprouts generate heat as they grow, so good air circulation is important. Keep the jar in a spot that gets some airflow, away from direct heat sources. You can also leave the lid off for a few hours each day to increase oxygen flow. This will help prevent mould growth and keep your sprouts fresh.

Enjoy Quickly

Bean sprouts have a short shelf life and are best eaten within 3 to 5 days of harvesting. Their delicate nature means they can spoil quickly. After harvesting, rinse them, pat them dry with a towel or paper towels and enjoy them immediately. You can store any leftover sprouts in an airtight container in the refrigerator for up to 2 days.

Optional: Greening

If desired, you can “green” your sprouts by exposing them to light during the final stages of growth. About 2 days before harvesting, place the jar in a spot that gets lots of indirect light, such as near a window. The light will stimulate production of chlorophyll, giving the sprouts a green hue. Green sprouts tend to be slightly more bitter but also contain more nutrients. Either way, your sprouts will still be perfectly edible and delicious!

Growing your own bean sprouts at home is easy and rewarding. Follow these simple tips to keep your sprouts fresh, and you’ll have a steady supply of nutritious microgreens to add to your meals. Your taste buds and your body will thank you!

Harvesting and Eating Your Homegrown Sprouts

Rinse and Drain

Once your sprouts have reached 1 to 2 inches in length, they’re ready for harvesting. Give them a final rinse to wash away any dirt or debris. Gently drain the excess water by shaking the jar or using a colander.

Enjoy Immediately

Bean sprouts are best eaten immediately after harvesting as they only last 2 to 3 days when refrigerated. Their crunchy texture and freshness are best appreciated right away. You can add the sprouts to salads, sandwiches, stir-fries or eat them on their own. Mung bean sprouts have a nutty, earthy flavour while soybean sprouts tend to be slightly sweet.

Handle Gently

Since sprouts are fragile, handle them carefully after harvesting to avoid bruising them. Give the sprouts a once over to ensure there are no rotten or spoiled sprouts before eating them. Discard any sprouts that look slimy or have a foul odour.

Nutrient Boost

Homegrown sprouts provide you with a concentrated source of vitamins, minerals and other beneficial plant compounds. They have high amounts of vitamin C, vitamin K, folate as well as antioxidants like quercetin and kaempferol. Sprouts are also a good source of protein for their size and are cholesterol-free, gluten-free and low in calories.

A Fun Gardening Activity for Kids

Growing sprouts is a fun and educational activity for children. Kids can observe how a tiny seed transforms into a living plant in a matter of days. Sprouting teaches children about nature and where our food comes from. Kids will also love adding the crunchy sprouts they grew themselves to their meals and snacks.

In just a few short days, you’ll have a jar full of homegrown sprouts to add to your daily fare. Growing your own sprouts is rewarding and will provide you with nutritious microgreens to enhance your diet. Enjoy your harvest!
