Summer drought is one of the biggest threats to NJ lawns. But with the right approach, you can keep your turf healthy even through extended dry periods — without running your water bill through the roof.
Recognize Early Stress Signs
Grass under drought stress will show a blue-gray tint and footprints will remain visible after you walk across the lawn. These are early warning signs — if you see them, increase watering before the grass goes dormant.
Water Deeply and Less Often
Deep, infrequent watering encourages roots to grow deeper into the soil where moisture is more available. Aim for 1 inch per week in a single or double session rather than daily light watering.
Raise the Mowing Height
Taller grass shades the soil surface, dramatically reducing evaporation. In peak summer, set your mower to 3.5–4 inches. Avoid mowing stressed grass — wait until conditions improve.
Let It Go Dormant If Needed
Cool-season grasses naturally go dormant in heat and drought. This is normal — the grass isn't dead, just conserving energy. Avoid heavy use of dormant turf and it will green back up when temperatures drop.
