Midsummer in Flatbush and Lake Katrine, and the neighborhood streets of the Town of Ulster smell like warm grass by ten in the morning. Ulster Lawn Care handles the mowing and trimming on those blocks, along with the cleanups that open and close the growing year. A lawn here can put on a startling amount of height between one week and the next, especially after an evening thunderstorm walks up the valley. Cutting it back level, with the trim work done around the beds and posts, is a small and complete result. The same yards get raked clear when the maples give it up in October.
