WHEN AND HOW LONG TO WATER YOUR LAWN AND SHRUBS
The best time of day to water for reduced evaporation and decreased time the blades are wet is from 5:00 to 7:00 AM, but the acceptable range is from midnight to about 9:00 AM while grass blades are already wet from dew. Because of increased disease potential, the worst times of day to water are late morning (9:00 AM to noon) and late afternoon to early evening (5:00 - 7:00 PM). Mid afternoon watering can cool the grass crown and reduce summer heat stress. Water anytime if the lawn is in water stress or if local restrictions regulate hours.
Lawns need about 1 inch on clay soils and 1-1/2 inch on sandy soils of water per week, rain plus irrigation, to actively grow.
Overwatering is more of a problem then underwatering. Too much water leads to a condition called waterlogging which results in poorly developed root systems and greater probability of diseases like necrotic ring spot, anthracnose, and summer patch.
This recommendation is just a GUIDE for the Morris County, New Jersey area, for customers with a irrigation system installed by a Certified contractor. Amount of water may vary, based on wind, soil conditions, property grade and sun exposure.
