This time of year if I see "spurge" in the 'main lawn' (not just the edges)", I know right away that this lawn has been routinely mowed way too short! Spurge is a 'true indicator' that the homeowner is mowing way too short on cool-season turf. Recently, we have had two "srevice calls" regarding "weird weeds". Both were crabgrass + spurge. Both cases: 2 1/4 - 2 1/2 inch mowing height. Now they want free crabgrass killer. What would you guys do??? rscvp p.s. We always leave info regrading "proper mowing of Kentucky bluegrass" whenever we treat lawns.
