Q.    What are my responsibilities as a homeowner?
    A. Perform quarterly visual inspections - Maintain the irrigation system by performing quarterly daytime visual inspections, replacing broken heads, cleaning the filters in each head, fine tuning coverage area, and clearing grass and soil away from heads.  Also, make sure the irrigation system has a working rainfall sensor.  Call a licensed irrigation contractor if you choose not to do this yourself.
    A. Calculate time required to apply 3/4 inch of water - Apply 3/4 inch of irrigation water to each zone on the prescribed watering day.  Use a rain gauge to measure the time needed to apply 3/4 inch and set timer appropriately for each zone.  As part of the quarterly inspections, check different zones around the lawn as different sprinkler heads and patterns will yield different results.
    A. Watering Restrictions vs. High Heat - Irrigation of the lawn under current watering restriction rules does not approach the quality of a soaking rainfall.  Under drought conditions and summer heat (90 degrees plus), a lawn in full sun will probably need localized hand watering of dry spots.  The current water restriction guidelines allow had watering via hose and nozzle any day and time of the week.
    A. Water in lawn care products within 24 hours - This includes all insecticides, herbicides, fungicides and fertilizers.  Watering does not have to coincide with your normal irrigation days.  Most lawn care products begin to break down in the presence of sunlight and need to be watered in for maximum effectiveness.
    A. Keep lawn above 4 inches in length - Place mower on driveway and measure from the pavement to the bottom of the blade.  Lawns cut lower than 3 inches when temperatures are above 90 degrees will likely die in areas and need replacement sod.  Any insect controls that have been applied will break down faster due to higher ground temperatures and greater sun exposure.  Also, lawns cut at highest setting (4 inches plus) need much less water to thrive...
    A. Don't cut more than 1/3 height at a time - Never remove more than 1/3 of the height of the grass at any one time.  Doing so will stress the lawn.  Weekly mowing during growing season will prevent this.  Sharpen mower blades frequently as dull blades will shred and cause greater moisture loss in the grass leaves.
    A. Stop mowing in November - Discontinue mowing around the middle of November as growth slows and cooler temperatures prevail.  This will help to protect the lawn from frost damage and possible freezing temperatures until Spring.  During this time use a rake to collect and bag any leaves and not the mulching blade or bag on the mower...

Q.    How do I control my crabgrass in St. Augustine grass?
    A.    Unfortunately there are no current labeled products that do a satisfactory job at selectively controlling crabgrass in a St. Augustine lawn.  Hand pulling and/or treating with Roundup then re-sodding are the only current methods available.  some people have tried using baking soda but our experience with it has been unsatisfactory.
