When fighting dandelions in a lawn, I know it is common practice to dead-head the yellow flowers before they morph into the pappus stage with the feathery seeds, but will the seeds in the yellow flowers germinate if left in the lawn?
A neighbor told me that they will, but I question it. Are the seeds fertile/mature at that point? Once the yellow flowers are plucked from the plant, can they still mature while on the ground? I can not find info on this anywhere on the interwebs.
