Late in May the canals of the Klamath Project fill and the flats east toward Olene and Poe Valley turn from sage-gray to green in what feels like a single week. Spray & Grow Landscape Services works that quick turn, putting fertilizer down when the soil has warmed enough to use it and knocking back dandelion and thistle before they set seed across a whole yard. Alkaline, sun-baked ground in this valley wants help getting water down to the roots, so aeration and overseeding are as much a part of the season here as the mowing that follows. Regular cuts keep the turf thick enough to crowd weeds out on its own, which is the quieter half of the job. There is real satisfaction in driving past in August and seeing a lawn that stayed green in a country that mostly does not.
