Spring planting is right around the corner (or it’s already here, depending on your location), and whether you are looking to start a garden or simply find a fun family activity, we’ve got you covered! Starting seeds with your kids is so easy, and it’s a great way to introduce them to the wonder of watching seeds turn into plants.

To get started, you will need one or more empty milk containers (we recommend half-gallon cartons, but gallon or quart containers would work as well). You will also need seeds, potting soil, water, plastic wrap, and a medium-size rubber band (optional). In a few family friendly steps, you and your kids will be able to watch your seeds sprout indoors for a window garden or in preparation for outdoor gardening.

What kind of seeds should I use?

If you’re doing this with your kids, letting them choose a few of the items to grow helps them feel more attached to their little sprouts. Flowers like zinnias, petunias, and marigolds are always a good choice as they’re colorful and can be transplanted outdoors or put in hanging pots if desired.

Leaf lettuces are fantastic for growing in gallon jugs in a sunny window. The leaves can be picked as needed for salads and sandwiches.

Herbs are also fun to grow with kids—choose ones that are aromatic or that you’ll use frequently in cooking, like mint, thyme, parsley, cilantro, and oregano. Woody herbs like rosemary are tasty, but they take longer to grow and can be higher maintenance.

Get creative! You can even plant multiple types of plants in the same container to create combinations that are pretty and possibly edible!

How to start your seeds in milk cartons

  2. Caring for your plants: Water every few days, just enough to moisten the soil but not get soggy. Rotate your carton every couple of days for increased sun exposure on all sides.
