Egg Carton for Seedlings
Egg cartons can also be used as a replacement for tiny plant pots when you’re trying to grow seedlings. There’s no need to throw away your cardboard egg cartons because you can easily upcycle them.
After growing your seedlings in egg cartons, you can directly plant them in your garden because cardboard is biodegradable and it will quickly disintegrate. It’s also highly recommended to cut tiny slits at the bottom of the cardboard cups, making it easier for the plants to expand their roots.
