What causes stress damage?
Inadequate watering will result in a thinner lawn with poor color that is more susceptible to insects and disease. If the grass is actually in drought stress, broadleaf weeds and weedy grasses may outgrow the turf and create an uneven appearance. Grass plants that are in drought stress are also easily damaged by foot traffic and mowing. The grass is not growing, so it has less moisture to protect the cellular structure from collapse and permanent damage. Even mowing the grass high just to cut off tail weeds can result in lawn damage.
