Artondale Creek runs thin through September and finds its voice again with the October rain, and the lawns along it green back up almost overnight. Harbor Roots Landscaping and Lawn Care LLC works that turn of the year — mowing while the grass is still climbing, clearing fallen leaves before they smother it, keeping edges from creeping into the beds. The ground here is glacial and stubborn under a soft skin of fir duff, and turf grown on it answers to steady attention rather than heroics. A lawn cut at the right height in autumn heads into the dark months looking deliberate instead of abandoned. Then comes the particular pleasure of an even yard under a low grey sky.
