I'm trying to reclaim a big flower bed that has been neglected for a
couple of years. Rather than spray it with Roundup, I've been digging
out the weeds (mostly dandelions.) The depressing thing is that the
ground is white with dandelion seeds, but if I cover them with mulch
maybe the earthworms will eat them.

At this point, I'd be tempted to hit them with the weed burner.
