In Fort Worth you need to water your lawn about once a week. Grass needs around an inch of water a week to maintain a plush green. Although you may want to water more, this can lead to fungal diseases. When Fort Worth temperatures are expected to reach over 100 degrees a second watering per week may be necessary to combat water loss due to evaporation (but only if restrictions allow it).
The best time to water your lawn is between 4 am and 6 am. This both conserves water by preventing evaporation from claiming it and provides a good, healthy start to the daily growth cycle. The sun hasn't had time to raise the ground temperature so the water will be able to leach down into the soil where the plants take it in at the roots. A well hydrated lawn will be much more likely to survive the hot and dry conditions during the Texas summer.
A professionally installed sprinkler system is the best way to get even coverage over your lawn. It is also the most efficient watering technique.
Your sprinkler system comes with a controller module. It can be programmed to turn the sprinkler on and off at set times during the week. You determine the length of the watering as well as the time of day. Controllers should be hooked to rain sensors that will automatically bypass the scheduled watering cycle if it is not necessary.
A rain sensor is a small disk that swells in the presence of water and shrinks as it dries out. When the disk swells it closes off the sprinkler valves and triggers a mechanism that prevents the controller from operating. This sensor will also prevent over watering when there has been a light amount of rain in the same manner.
