Tips for a Green summer Lawn
• Keep your lawn a little long. Longer lawns do a better job of retaining water and standing up to heat. If you can, wait for a cooler day to mow and you will minimize water loss.
• Skip the lawn fertilizer. Extreme heat and lawn fertilizer are a bad combination. You’re likely to damage you lawn. If you can, fertilize your lawn in the fall.
• Water in the early morning. Early morning watering is a good idea for lawn care throughout the year, but during extreme heat, it is particularly useful in fighting evaporation.
• Water deeply. Light and frequent watering may seem like a good idea for a parched lawn. However, a deep watering two or three times a week works best, particularly during hot weather. Deeper watering helps the lawn extend its roots deeper into the soil.
• Mow late or early. Don’t mow your lawn in the blazing sun of a 90-degree day. Skip the heat stroke and wait until evening.
