DeKalb sits on some of the deepest black dirt in Illinois, and it shows in the yards every May, when everything comes on at once. Hernandez Landscape & Tree Service LLC keeps that growth in hand with regular mowing, string trimming, edged borders, and cleanups in spring and again in fall. Soil this rich means a lawn will forgive plenty but never stop growing, so the calendar matters more than any single visit. There is a particular pleasure in the first cut of the year on a yard that was kept clear all winter. The lines go in straight and the season starts the way it should.
