There is a week in April when Delta changes color. The ditches come up, water runs in channels dug by hand a century ago, and lawns that spent the winter the same buff shade as the adobe hills go abruptly, ridiculously green. Delta Lawn Care, LLC meets that week with sharpened blades and begins the long rhythm of mowing and trimming that carries through October. The first cut of the year is the one worth watching — a yard remembering what it looks like. After that it is steady going: even height, borders cut in sharp, and a lawn that comes back a little better every time it is touched.
