Starts your seeds off right
Get fresh herbs and flowers off to a good start by planting them early and letting them sprout indoors. Once they have grown a bit you can then transfer them into the ground or pots, but this is an easy and cheap way to get them going. Use the egg cartons (styrofoam cartons need less watering)that you would have tossed out anyway, seeds of any kind, and a little soil…..too easy!
Make sure you mark what seeds are planted in which egg cartons. I dipped popsicle sticks in chalkboard paint, so if I grow different plants next year I can reuse them.
