Here’s an innovative tool that takes the mystery out of correct seed spacing. Simply make a furrow, lay down the correct guide, pour in some seeds, and nudge each one into its planting hole. Then simply pinch up the soil to cover the seed. The 23″ guides are better for long rows and the 11″ guides are ideal for square foot gardening. Accurate seed placement means less thinning, and better use of seeds. Growing vegetables to full size means providing the room to grow next to their neighbours. These planting guides take the guesswork out of seed planting.
