It is important to understand that a lawn that is easy to care for and gives you the health and beauty you desire is dependant on several steps including those that occur before you make your first application of fertilizer.

St. Augustinegrass, the type of grass in most Florida homes, comes in many subtypes called varieties and have different characteristics that make them more or less suited for various conditions like shade tolerance and others. The term lawn or turfgrass as found below will be used interchangeably to refer to St. Augustinegrass.

1. Turfgrass Establishment:
Successful turfgrass establishment is important because without it lawns perform poorly and become infested with weeds that later can be difficult or impossible to selectively control. Proper soil preparation followed by the selection of quality sod that is of the appropriate variety (cultivar) for your general shade conditions, combined with properly installed irrigation all contribute to the success of turfgrass establishment.

Neglecting any of these important steps can lead to necessary corrective action in order to maintain a healthy desired lawn. This action can include removing sod from an area that is too shady for grass to grow and replacing it with a more shade tolerant plant material, pruning a tree to allow more sunlight, adding or moving sprinklers, or removing the existing weed infested areas and re-sodding with the appropriate variety following proper soil preparation.

2. Mowing:
St. Augustine grass should be mowed frequently enough to never remove more that one third of the grass blade and always with a sharp mower blade.Mowers should be set on the highest setting for all varieties other than semi-dwarf varieties such as Seville and Delmar, which should be mowed at about two and one half inches high. When mowing once per week, this practice can be easily followed during the slower growing cooler months but becomes more difficult during the fast growing rainy summer months.

A dull mower blade will split and tear the grass blades that will eventually die from their wounds. Split and torn grass blades can thin the grass, encourage weed growth, cause an entry point for fungus and detract from the overall appearance of the lawns color by combining dead grass blades with green healthy ones. Grass clippings should be mulched and returned to the grass to be used as an additional source of nutrients.

3. Irrigation:
Proper irrigation conserves both water and fertilizer and contributes to a healthy lawn by encouraging healthy root growth while discouraging weeds that thrive during constant wet conditions. Irrigation should be performed as needed by recognizing temporary wilt symptoms and then applying three-quarters of an inch of water. If a regular frequency is desired and you are in the St. Johns Water Management District, you must follow the irrigation requirements that allow watering only two times per week and only on specified days that correspond with your street address.You should then apply only three-quarters of an inch of water.
