Rain comes through in the night and by morning Tenakill Brook is running full, and the whole borough smells like cut grass that hasn't happened yet. American Green Lawn Care LLC waits out the soft ground, then goes — mowing at the right height for May, edging the walks back to a true line, trimming what a mower can never reach. Seeding and feeding go in when the soil is warm and willing, which in this corner of Bergen County is a narrower window than most people think. Beds are mulched, and hedges are taken in a little so the front windows keep their light. There is a particular satisfaction in pulling off a street at the end of a May afternoon and seeing it all standing up straight and green behind you.
