June in Bluebird Canyon comes with jacarandas dropping purple on the switchbacks and a sky that does not clear until nearly noon. My Botanica Inc. moves through those terraced yards while the morning is still soft, mowing narrow lawns and running the edger along stone risers and retaining walls. Terraced ground wants attention in both directions, so trimming and weed control travel uphill with the crew and the clippings travel back down. Fertilization is kept in step with the canyon's own wet-and-dry swing rather than a fixed date. A canyon lawn finished well looks like it belongs there, held neat between the walls that hold the hill.
