Late summer around Bremen can go three weeks without real rain, and by then you can read the dry spots in a lawn like a map. Specific Irrigation Systems deals in water — sprinkler systems put in, heads and lines repaired, zones tuned and timers set so a yard drinks early in the morning instead of at noon — along with mowing and upkeep once the grass is thriving. Even coverage is the whole trick, because a lawn is only as green as its thirstiest corner. Come back after a dry stretch and the turf runs uniform right out to the edges. That is quietly one of the more pleasing sights in this line of work.
