The most demanding garden chore for July is watering. We associate these plants with the typical Northwest landscape, but they are all native to areas that receive considerably more summer rainfall. Apply water slowly and let it penetrate into root systems. Their roots are not yet established. The same is true for any plant that was transplanted during the past dormant season.
Water is a precious and limited source here and throughout the world.
But conservation is one of the constant needs of the region every summer. Go for deep, slow watering. Be sure to use mulches 2 to 3 inches deep around shrubs and trees. If the mulch is applied now to damp ground, it will help retain moisture already in the soil. It's delightful to stand with a hose in hand, sprinkling plants the ground and bare feet, but this is the least efficient way to use limited water resources.
