There is a week every October in Jefferson Township when the oaks let go all at once, and a wooded Oak Ridge property can vanish under its own canopy overnight. HSK Outdoor Services is out for that week and for all the ordinary ones on either side of it — mowing through the growing months, trimming along the tree lines, edging the walks and drives that thread back through the timber. Spring cleanups pull the winter's fallen branches and pressed leaves off so the grass can find light again. Fall cleanups keep the lawn breathing until frost. Outdoor work up here is mostly a negotiation with trees, and it is a good one to win.
