FYI These babies grow fast, keep them outside all the time or just for the night. Mine grow ½ inch/day! Wash the daffodill bulbs, put them into a glass cylinder with some pebbles and water. To make the washing easier, let them soak some hours before you start. I washed the bulbs like baby hair, trying not to damage anything. The other cylinder with more black pebbles has already a smaller cylinder inserted. Glass eggs from Pentik.
