What is the best time for nighttime watering?

Watering just before dawn is the best practice for several reasons. At this time, the temperatures are cooler, which minimizes evaporation. When the sun begins to rise, the plants can absorb the water effectively as they prepare for the day ahead. This timing helps ensure that the grass and plants get the moisture they need without losing a significant amount to heat or wind, which can occur during the day.

Additionally, watering in the early morning allows for the foliage of plants to dry out during the day, reducing the risk of fungal diseases that can thrive in damp conditions. This practice promotes healthier plant growth and is more efficient in terms of water usage, making it both eco-friendly and beneficial for the landscape.
