Soil Preference of St. Augustine Grass:

     St. Augustine grass cultivars are tolerant of a wide range of soils and soil PH levels

Shade Tolerance: 

     St. Augustine grass is among the most shade tolerant of the warm season grasses with some varieties of St. Augustine tolerating shaded conditions extremely well including ‘Bitterblue’ in the normal growth habit range and ‘Seville’ in the dwarf growth habit cultivars.  

Salt Tolerance of ST. Augustine Sod: 

All varieties of St. Augustine sod have good salt tolerance and are extensively used in Florida’s coastal areas. It is tolerant both of salt spray and sodic soils. 

Water Requirements for A St. Augustine Grass Lawn: 

    Established St Augustine grass should be watered on an as needed basis. When leaf blades begin to turn a gray green color, fold up or when footprints remain on lawn after walking across it then you know it is time to water your lawn. Apply ¾ inch of water with an irrigation system or sprinkler watering to a depth of 8-12 inches deep in the morning if possible before 10 am to avoid water loss through evaporation.  

    Watering frequency will vary with the seasons and local rainfall levels, but take care not to decrease the water quantity at any time, adjust water frequency. This helps not only to drought proof your lawn but keep it healthy and free from disease as well.  

 

Mowing Requirements: 

CAUTION – St. Augustine grass sod requires a different approach to mowing than all other warm season lawn grasses! 

Standard ST. Augustine Sod      

    Mow cultivars of Standard St. Augustine grass sod to 3.5 – 4 inches tall! Repeatedly mowing at a lower height can increase the stress on your lawn, thereby increasing lawn problems including shallow grass roots, increases susceptibility to pest problems and lowered defense against diseases.  

Dwarf St. Augustine Sod

     Dwarf varieties of St. Augustine grass sod should be mowed at 2 – 2.5 inch heights

Traffic Tolerance: 

St Augustine grass sod has lower traffic tolerance

 

Fertilizer needs: 

     St. Augustine grass lawns will require at a minimum of  2 times a year in the spring and again in the late summer fertilizer application including a complete fertilizer like 16-4-8, 10-10-10 or 6-6-6 with micronutrients at the rate of 1 lb of actual nitrogen per 1000 s.f. of grass area. Grass clippings should be left on lawns being minimally maintained. 

    For optimum appearance, St. Augustine lawns will need an additional 2 times a year. The Early spring (March) then the twice additional in summer (May and again in July) then the late summer or early fall application in September. For a total of 4 applications yearly.  

    A happy medium would be an early spring application of a complete fertilizer such as 16-4-8, an early summer nitrogen only and a late summer complete fertilizer such as 6-6-6, along with  incorporating grass clippings into the lawn with a proper mowing and watering care for a healthy, deep green lawn you can be proud of. 

 

Pest Problems: 

     Chinch bugs are the major insect problem of St Augustien grass lawns. Fortunately there are chinch bug resistant varieties such as Floratam and Floralawn. Other pests include sod websormarmywormsgrass loopersmole crickets,white grubs and nematodes. Remember, high levels of nitrogen fertilizer increase insect infestations.  

Disease Problems: 

     Brown patch and gray leaf spot are the most common St. Augustine grass lawn diseases. Both diseases can be controlled with fungicides such as copper sulfate applied as a foliar application.  

Establishment methods: 

     St. Augustine grass can be established by soddingsprigging and plugs
