Timing is crucial when it comes to watering your lawn, especially in the Mid-Atlantic region, where seasonal weather patterns vary significantly. Knowing when to start watering in the spring and the best times of day to irrigate can help maintain a healthy lawn while conserving water.

In the Mid-Atlantic, the best time to start watering your lawn depends on temperature trends and rainfall. Generally, irrigation should begin in mid to late spring, around April or early May, when temperatures consistently rise above 50°F, and grass begins active growth. However, natural rainfall often provides sufficient moisture early in the season, so it’s essential to monitor soil conditions before turning on your system. If the soil feels dry and footprints remain visible on the grass, it’s a sign that watering is needed.

When to water

  • The optimal time of day to water your lawn is early morning, between 4 a.m. and 9 a.m.
  • Temperatures are cooler, and winds are calmer, allowing water to soak into the soil rather than evaporate.
  • Watering in the morning also helps prevent fungal diseases, as grass blades dry quickly under the rising sun.

When to avoid watering

  • Midday watering is inefficient due to rapid evaporation caused by high temperatures and strong sunlight.
  • Avoid watering in the late afternoon or evening, as cooler nighttime temperatures and lingering moisture can encourage mold and lawn diseases.

To ensure proper hydration, lawns in the Mid-Atlantic typically need about 1 to 1.5 inches of water per week, including rainfall. Smart irrigation controllers and soil moisture sensors can help regulate watering schedules and prevent overuse. By starting irrigation at the right time and following best watering practices, homeowners can maintain a lush, healthy lawn while promoting water efficiency.
