We want to set the stage for success in the garden with plants that are easy to grow, so that kids have the chance to feel empowered and rewarded when they get to collect their first harvest.


This guide focuses on a few easy to grow plants that thrive indoors before transplanting, making the experience fun and educational for children.



Why Start Seeds Indoors with Kids?


Indoor seed starting gives children a chance to watch plants grow from tiny seeds into healthy seedlings. It’s also great way to bring nature inside during colder months or before the outdoor growing season begins.


Kids can learn about soil, water, light, and the life cycle of plants in a controlled environment. This project encourages curiosity and pride as they see their efforts turn into real plants.

What Are Some Fun Plants To Start Indoors With Kids?


Choosing the right plants is key to keeping kids engaged and ensuring success. Some of the qualities we look for are the seed germination rate, how long it takes to harvest, and the amount of yield a plant gives.


When starting a garden for kids you want to consider plants that are quick to grow and that give you multiple harvests that way it can be more engaging for them.


Also consider growing ingredients that your child already enjoys eating as a great way to spark interest in what they are growing in the garden.


Here are four plant varieties that are easy to start indoors and fun to grow when you're teaching kids how to grow food at home.
