Lawn and Garden Watering
Many conventional lawns in Minnesota can stay healthy if they receive 1-1.5 inches of water a week, either through precipitation or irrigation. Deep infrequent, watering is generally better for lawns and plants than frequent lighter irrigations, which can cause shallow roots.
Interesting fact: “For every 1% that you increase your soil’s organic matter, you increase the water absorption capacity by 16,000 gallons of plant-available water per acre, down to one foot deep” (EPA).(Metropolitan Council)
