Very few lawns need "weed and feed," but millions of bags of this
stuff is purchased every year. Apply weed killers when weeds are
young and actively growing. A dry sunny day is best. Spot treatment
is better in that your grass is not "punished" and you are using less
chemical yet the weeds are treated.

Years ago, the procedure was to apply lawn fertilizer. Wait 2-3
weeks, then spot treat the weeds. The idea is that the fertilizer
puts weeds into active growth which is when the weed killer has the
best effectiveness.
