West of the city center the land begins to climb toward the first Watchung ridge, and the streets off Highland Avenue tilt just enough that every front lawn is a small hillside. Green Roots Organic takes care of those lawns — mowing across the pitch, edging the walks and steps, trimming the borders, and running the spring and fall cleanups that reset a yard. Sloped turf in Orange holds water differently at the top than at the bottom, and it shows in how it greens up in May. Learning a block's habits is half of it; the other half is arriving when you said you would. What comes of it is a run of tidy green squares climbing the hill, which is a fine thing to look back at.
