A Bed-Stuy backyard is thirty feet of possibility behind a hundred-year-old wall, and in May the light lasts long enough to finish the job. Bed-Stuy Garden Guy mows those small lawns, trims the hedges tight along the fence, weeds the beds and mulches them dark so the green reads brighter. Around the corner the maples in Herbert Von King Park are fully out; the same spring is happening behind every parlor floor on the block. The payoff is a stretch of grass short and level enough to sit on with the back door standing open. Lawn and garden care in Brooklyn.
