Yard care and water savings tips
• Improve poor lawns with aeration, over seeding and top-dressing with compost.
• Aerate in spring or fall to improve root development and water penetration.
• Follow by overseeding thin areas. Ask your local nursery for grass seed blends adapted to our area.
• Aerate your lawn at least once a year so water can reach the roots rather than run off the surface.
• Use a broom instead of a hose to clean driveways and sidewalks.
• Don’t leave the hose running while washing your car.
