Irrigation
HOSE & SPRINKLER
Irrigation can be done in two basic ways – with a hose and sprinkler or with an in ground irrigation system.
When using a hose and sprinkler, place the sprinkler in the area that is driest. Allow the sprinkler to run the proper length of time. For most Florida soils, apply no more than ¾” of an inch of water per application is enough to replenish the grass.
You can use the “can method” to determine how much water to apply and to see if you are watering uniformly across the landscaped ar4ea. Place 5 to 7 wide-mouthed, flat-bottom cans (can about the size of an average tuna can) throughout the area to be irrigated. Wait 30 minutes, and then measure the depth of water in each can. Average the measurements and use this number to determine how long you need to water to apply three-quarters of an inch of water.
IN GROUND IRRIGATION SYSTEMSThese can be automatic or manual, or a combination. The automatic system is set for a predetermined time of the day and days of the week. Make sure it is set for before 10 am or after 4 pm. And as with the hose and sprinkler method, set it to apply no more than three-quarters of an inch of water.
During extended periods of rainy weather, irrigation should be turned off.
Don’t water your street, driveway or sidewalk. Position you sprinklers so that you water lands on the lawn and shrubs…not the paved areas.
Water your lawn only when it needs it. Typically, Florida lawns need water up to two times a week in the spring and summer, less if it rains, and less in fall and winter. Over watering your lawn results in shallow root systems, which means you lawn is less drought and stress tolerant. Over watering also promotes weed growth, disease and fungus.
Irrigation hours: Water lawns during the early morning or early evening hours when temperatures and wind speed are lowest.
St. Johns River Water Management District rules allow watering only before 10: 00 am or after 4:00 pm.
