Spring is here, and a few things done now can help keep lawns healthy during the summer. Washington County Extension Education Director Gene Mohling care needs to be taken when considering fertilizer options. He says its best to start with a soil sample. Mohling says once the yard has greened up and been mowed twice, it's time to start looking for weeds. He says many lawn and garden stores carry a spring time granule that will fight weeds, and fertilize at the same time. For more information call the Washington County Extension at 319-653-4811.
