Dogtown in October is oak leaves and glacial boulders, cellar holes going quiet under the ferns, and a wind that empties the canopy in about a week. LaChance Tree Professionals meets that week head-on in Gloucester yards — leaves gathered and hauled, beds cleared, shrubs and hedges pruned back to a shape that will carry the winter. Through the growing months the work is mowing and trimming, edges cut, mulch refreshed, and the spring cleanup that gets a yard out from under its own debris. Overseeding fills in what the shade has thinned. A raked lawn under bare oaks has an order all its own.
