Hey--another positive about dandelions--their long tap roots will help break up clay soil.
Sometimes they will wisely choose to reseed next to the back side of a larger plant and will stay hidden until their root "seems" 3' long! When digging it out (if you listen real hard) you will hear the faint musical taunt "naa-na-na-naa-naa" because you have unknowingly left a half inch of root in the ground which will sprout another cycle.
Okay...the word is out now....I hear voices when I'm in the garden
