My "resting" garden plot has been invaded by several dozen tree-like
dandelions. Inattentive maintainance allowed this. At first I dug
the buggers up individually but the roots are 18-20" deep. Worse,
those that I have managed to dig out successfully show off-shooters
from broken or missed pieces.

I don't want to start throwing down my consumer-grade agent orange
but it's now reached epidemic proportions. My plot looks like I'm
cultivating the yellow buds for commercial distribution throughout
my neighborhood. Is there a way of ridding my garden area of these
pests without resorting to chemical purfication?

Many thanks.

Find some pet rabbit owners. Offer them access to your dandelion. Bet
you some will accept your offer and harvest them for bunny treats.
After a while you won't have any left.
