Many new gardeners plant their bulbs so far apart that they look like the trail of pebbles Hansel dropped behind him in the woods so he and Gretel could find their way home. In other words, much too far apart.
|TOO FAR APART:||TOO CLOSE TOGETHER:|| JUST RIGHT:
If you are planting large bulbs (tulips, daffodils, hyacinths), more than 6" (15 cm) apart is too far. If you are planting small bulbs (crocuses, snowdrops, Dwarf Irises, scilla, muscari, anemones, Lilies of the Valley), more than 3" (8 cm) apart is too far.
