Come October the hickories and oaks in the hollows around Goshen let go all at once, and a lawn can disappear under them in a single windy afternoon. Spark Lawn Care Ltd. shows up for exactly that, moving leaves off the turf and out of the beds until the green underneath comes back into view. The mowing keeps going as long as the grass asks for it, a little higher, a little slower, with the edges kept sharp so the yard holds its shape into the cold months. There is a particular pleasure in the last blower pass of the day, when the walk is bare, the porch is clear and the light is coming in sideways and gold. Autumn here is loud and brief, and a yard is better for meeting it head on.
