Fescue is a grass among many of the popular types for home lawns in transition and northern zones. The hearty drought and heat tolerant grass is disease resistant but shouldn’t be watered daily. Installing a lawn irrigation system makes maintaining and growing a healthy fescue lawn easier if you know the best way to utilize your system for maximum results.
Homeowners should have a drawing of their irrigation zones and where all the heads are located for each zone. If you don’t have one, draw a rudimentary layout of your yard and mark the heads on it. Keep note of where the fixed spray popup heads and stream spraying rotating rotors are. Each zone should have one or the other, but not both on the same zone. If both are noticed on the same zone, a professional can help fix the situation.
To allow the fescue to grow the best, less frequent heavy watering gives the grass the water it needs while still allowing necessary oxygen to be absorbed as it dries. For best results, the lawn irrigation controller should run rotor zones for one hour and popup spray head zones for about 20 minutes. The system should run at least three days apart such as Monday and Thursday. During hotter months, consider watering three days per week. Water less often in fall and early spring.
In most regions, homeowners should turn on their sprinkler system around Easter and turn it off by Thanksgiving. Different climates may dictate earlier or later shut off and start times depending on weather and amount of rainfall in the area. Additionally, consider shutting off the system after a heavy rainfall for about four days. Wait to mow 36 hours after watering and water the lawn early in the morning.
During extremely hot times, the fescue may brown and go dormant. This is normal but continue watering and infrequent mowing to keep the lawn healthy. Lawn irrigation properly used can keep your fescue lawn healthy and looking beautiful.
