Summer in New Jersey puts significant stress on lawns and gardens, especially those made up of cool-season grasses like tall fescue and Kentucky bluegrass. These grasses require about 1 inch of water per week (including rainfall) to stay healthy during peak heat. Without consistent and proper watering, lawns can quickly turn brown, thin out, and become more vulnerable to weeds and disease.
Timing is just as important as quantity. The optimal window for watering is early morning between 5–9 AM, when temperatures are cooler and evaporation is minimal. Watering during the evening may seem convenient, but it leaves grass wet overnight—creating ideal conditions for fungal diseases to develop. Proper timing ensures water is absorbed efficiently while minimizing risk.
To water effectively, homeowners should calibrate their irrigation systems using a rain gauge or simple container test to measure how much water is actually being applied. Skipping proper watering practices can lead to uneven growth, wasted water, higher utility bills, and long-term lawn damage. A consistent summer watering plan keeps your lawn resilient and healthy through the hottest months.
