Eggshells on the counter
Save your eggshell halves, set them back in the carton, and poke a small drainage hole in the bottom of each one with a pin or needle before adding soil. Fill them with a little potting mix and drop in a seed. They're the right size for a single seedling, and when it's time to transplant, you just crush the shell into the soil. It's one of those projects that feels like a little magic trick from start to finish.
Microgreens on a tray
This one is built for impatient kids. Spread potting mix across a shallow tray, scatter radish seeds densely across the surface, mist with water, and set it somewhere bright. Radish microgreens are ready to snip and eat in 7 to 10 days. Snipping their first harvest is genuinely one of the best moments a kid can experience in gardening.
A mason jar herb garden on the kitchen shelf
Basil, chives, and mint can all grow in jars, just add a layer of rocks or pebbles to the bottom first, since mason jars don't have drainage holes. Set a few on a sunny kitchen shelf and your kid has a garden they walk past every day, which means they actually remember to water it. There's also something really satisfying about cooking with herbs your family grew together.
A hanging colander
Line a colander with a coffee filter, fill it with potting mix, and plant strawberries or trailing herbs. Hang it from a hook near a window or outside a door. It drains well, it's easy to water, and kids love watching their plants spill over the sides as they grow.
Ready to take it to the window?
The KiwiCo Window Garden crate is designed exactly for this. Kids assemble their own suction-cup planters, stick them right to the glass, and grow green beans and squash from seeds. As the plants come in, they learn to identify the different parts — roots, stems, leaves — and eventually cook with what they grew. It's a full plant science lesson that lives on your window, not your yard.
