For two weeks in April the cherry trees around Kissena Park make Flushing look like somewhere else entirely, and then the petals come down and the season starts in earnest. Moreno Landscaping takes it from there — weekly mowing, edging along walks and curbs, trimming, weeding and mulching the beds, and carrying the cuttings out. Yards on these blocks run narrow and busy, hemmed by driveways and fences, which makes a clean edge the difference between tidy and overgrown. The spring cleanup opens the year and the November leaf haul closes it. In between, the grass stays short and the borders stay drawn.
