Late afternoon light comes in sideways through Reche Canyon, and the cut slopes above the road hold it a while before the shade climbs. Canyon Hydroseeding sprays those bare faces green — seed and mulch laid across ground that would otherwise wash — then waits out the weeks it takes a hillside to answer. New lawns begin the same way here: a whole yard seeded in an afternoon and watered into being. By the second spring the difference is hard to argue with, soil staying put and color where there was raw dirt. It is patient work with a long payoff, which suits a canyon that has never been in any hurry.
