time to start making plans for getting the lawns u maintain, off to a good start.about the middle of march ill go with a jump start, lite, quick release fert. this will not only get things rolling but will also bring up the weeds in the lawn . this is when they are most vunerable,and easy to kill. then after the weed killer has done its job ,a slow release fert treatment. not sayin everybody ought do it this way . just a suggestion for the new fellas.what u do now can really make a big difference in customer satisfaction and make them think u know what u doing. plus your lawns will look better than those around them.good luck in u season.
