What time of the day should I water?
It is best to water during the cool, early morning hours. Evaporation loss can be 60% higher during the day. In addition, by watering when the grass is already wet from the dew, you won't alter the natural state of the grass. If you must water in the late afternoon, stop watering with enough time before dark to allow the grass to dry. Watering at night is not recommended because water left on the blades of the grass encourages fungus and disease.
How long should I water?
For most Florida soils, an average of ½ to ¾ of an inch of water per application is enough to replenish the grass. It is best to saturate the root zone and then let the soil dry to encourage healthy, deep root growth. During hot, dry months, a full inch is recommended but you must follow local water regulations.
To determine how long to run your sprinklers, place several empty, straight-sided cans or cups at different distances within one zone. (Uniform coffee mugs work well.) Run the sprinklers for 15 minutes and measure the amount of water collected in each can. Calculate an average water depth and determine how long it will take to apply a ½ to ¾ inch of water.
Example:
· ¼” average depth of water after 15 minutes – water 35-50 minutes in that zone.
· ½” average depth of water after 15 minutes – water 20-30 minutes in that zone.
How should I water my Floratam, St. Augustine grass during the different seasons?
a. March through early June
March until the rainy season begins, usually mid-June, is usually the driest time of the year in southwest Florida. Often we receive just trace amounts of rain in May. This is the most important time of year to be diligent with watering your lawn. If the watering restrictions in your area allow for twice per week watering, and you apply the recommended amount of water each cycle, then your lawn will do just fine. However, if you are only permitted to water once per week, then you should expect damage in some parts of your lawn. A seven day watering interval is too long for Floratam when long, hot and sunny days are the rule. When the rains return, your Floratam will recover unless you failed to sprinkle heavily on your permitted watering day.
b. June through September
Twice per week watering is needed throughout this entire summer period. If the rains stop for a week, you must irrigate to avoid damage. However, because it often rains several times per week, you may not need to sprinkle at all.
c. October through February
During this period your Floratam will need less frequent water inputs. Especially as the days get shorter and the daytime temperatures moderate in the 80’s and even the 70’s. If the daytime temperate range in the 60’s to low 70’s, you can do without any additional sprinkling. |
