Some December mornings in Lincoln start with frost on the windshields and fog lying flat toward Sheridan, the oaks bare enough to show exactly how they are built. Lincoln Tree Services likes that season for it — with the leaves down, a tree tells you where the cuts belong. Dormant pruning takes out the rubbing limbs and the dry wood; trimming lifts low branches off the drive and the roofline before spring puts weight back into everything. Removal is handled where a base has gone hollow or a lean runs too hard toward the house to be trusted. And when a storm crosses the foothills and litters a yard, cleanup carries all of it off — brush, rounds and rakings together.
