Late winter is when a Riverside lawn quietly decides what kind of summer it is going to have, while the ground still holds the rain that came down off the Box Springs slope. The Land Chemist works that window — feeding the turf, treating the weeds that push up first, reading the soil beneath a lawn rather than only the blades on top of it. Grass in this valley is asked to do something genuinely difficult, and the gap between a thin lawn and a thick one is usually settled months before anyone notices the difference. Regular mowing and edging keep the rest of the year honest. Lawn treatment and care for Riverside and the towns next door.
