Egg Carton Seed Starters: The Gardening Shortcut

Six tiny radish sprouts broke through the cardboard walls of an Albertsons egg carton on a windowsill in late March, each poking up from a thumb-sized pocket of soil. The egg carton sat near the sink, soaking up the last of the afternoon sunlight, while the bottom stayed just damp enough to never dry out. Before anything was planted, the whole carton had been snipped in half-lid tossed, twelve little cups ready for potting soil and seeds. The cardboard always seemed flimsy, but within a week, it held enough moisture for seedlings without pooling water or rotting roots. By April 9th, each sprout’s roots had woven right through the soft paper, invisible until a gentle squeeze revealed the secret: you never need to pull the plant out. When transplanting, the entire cup-carton and all-drops right into the garden bed, cardboard roots and all, breaking down so the radishes can grow straight through into the soil.
