Weez, I remember starting marigold seeds in egg cartons when the kids were small. Marigolds sprout so quickly it keeps the kids interested in their "garden". Fun!
We just threw the old flowers down on top of the dirt and they sprout right there all on their own. What magic even for a seasoned gardener to see that happen!!!!!!!
And the COLORS and SIZES they have in those now adays, so many different ones.
