On a July evening the light comes across the Roxbury hills at a low angle, and that is when mowing lines stand out — bright one way, dark the other, running clean to the property line. Green Lines Landscaping & Design works for exactly that: cut, trim, edge, and leave a lawn that reads like it was drawn. Succasunna yards roll more than they appear to, and stripes on a grade take planning rather than luck. The beds get their borders back, the walks get cleared off, and the whole thing sits still through the last hour of daylight. Grass is a surface; how it is finished is the craft.
