in re: surgical strikes:

Dandelions and other taprooted plants, I've had fair luck with either a
little spritz at the center of active growth or severing the rosette and
spritzing/painting the taproot, if there is any resprouting, it is small
and weak and easily retreated. Non-geophyte plants that don't resprout from
the roots just have to be cut below the level of the first leaves. For
invasive geophytes, a combination of treatment and exhausting the storage
organs may be necessary (plus dealing with seeds or above ground bulblets).
