In general, turf
grasses need about – 1 inch of water per week to maintain green color and
active growth. During times of heat
stress 1 ½ - 2 inches. Use a straight edged cup or can (coffee
can, soup can) or at your local garden center they have Rain Gauges to
see just how much water your applying.
You may be surprised that you maybe under watering. However, during
certain times during the summer when high temperatures are the norm, you should
allow lawns to naturally slow down in growth during those extreme conditions.
You may let the lawn go almost completely dormant in hot weather. Many factors
such as the soil and weather all have a role in the lawn's water needs. Here
are a few guidelines to follow:
- Decide
before hand.
Decide before summer heat and drought conditions arrive, to either water lawns consistently as needed throughout the season, or let lawns go dormant as conditions turn hot and dry. Do not rotate back and forth. In other words, don't let the grass turn totally brown, then apply enough water to green it up, then let the grass go dormant again. Breaking the lawns dormancy actually drains large amounts of food reserves from the plant. - When
is it time to water?
The first few warm days of summer does not automatically mean to water lawns. In fact, allowing lawns to start to go under mild drought stress actually increases rooting.
Watch for foot printing, or footprints remaining on the lawn after walking across it (instead of leaf blades bouncing back up). Grasses also tend to turn darker in color as they go under drought stress. Sampling the root zone soil could be another option. - Water
as infrequently as possible.
Thoroughly water when you do water so moisture soaks down to the roots. Exceptions to this general rule would be for newly seeded lawns where the surface needs to stay moist, newly sodded lawns that have not yet rooted into the soil, or when summer patch disease is a problem (look up lawn disease) Otherwise, avoid frequent watering that promote shallower root systems and weeds (e.g., crabgrass) excessive thatch and disease activity. - Water
early in the day if possible.
Given a choice, water early in the day when lawns are normally wet from dew. Avoid midday watering due to excessive evaporation, and at night due to potential increased chances of some diseases gaining a foothold. The exception to this guide is when you are in extremely hot weather and nighttime temperatures don't go below 68 degrees. Then it is better to water in the late afternoon or early evening, providing you don't have watering-time restrictions. Early or late in the day reduces the amount of evaporation that takes place during the very hot day, allowing more water to reach the root zone. - Spread
the water uniformly across the lawn.
Sprinklers vary in distribution patterns, and require spray overlap for uniform coverage. Placing coffee cans or similar straight-sided containers on the lawn can help measure water application rates. Avoid flooding areas, or missing other spots. On heavy clay soils and slopes, watch for excessive runoff; it may be necessary to apply the water in several applications to allow for adequate penetration. - In short, watering once or twice a week heavy is better
than watering lightly every day.
- MOWING…Mow high. Use a ruler check mowing height. Mow at 3” and higher if possible in heavy sunny areas.

These work pretty well for
larger areas. It’s a “Water Train” which
travels across the lawn while watering.
Available at larger hardware/garden centers.
