Yard care and water savings tips
Water in the early morning or evening. If you water at midday, half the water evaporates.
When soil is dry or compacted it won’t absorb water quickly. If water puddles, stop watering a while then restart so the water has time to soak in.
Direct downspouts out into lawns and beds or “dry wells.”
Use compost and mulch to reduce erosion and help rain soak in.
Install a device that shuts off automatic sprinklers when it rains.
