I can't remember what color these are! But I have several patches just as thick as this one. I'd love advice on how to dig up these bulbs so I can spread them around the property more. Should be seeing blossoms soon!
Dig in fall. Just separate out all the little bulblets from the mature bulbs. Then replant your matures however you decide and put your bulblets where you want them to fill in or give them out to neighbors or family. A digging fork will probably serve you best. Beware: there will probably be hundreds of little tiny bulblets depending on how long your mother ship has been growing there undisturbed.
