Caring for Palmetto St. Augustine

St. Augustine lawns are prone to many  problems during the growing season. One  of the major problems we see with a   St. Augustine lawn is a customer using the  inappropriate herbicides on their lawn. Before applying any herbicide, read the entire label and make certain that the product is labeled for St. Augustine. If your lawn species is not  written on the label, do not assume that the product is safe.

Yet another problem with St. Augustine is  fungus. There are two fungus problems which become evident on most St. Augustine lawns during the warmer months of the summer.  The first fungus is grey leafspot. This fungus  presents small circular lesions on the leaves.  Although unsightly, grey leafspot is not life threatening to the lawn. Brown patch,  however has become a major disease on  the lawn during mid to late summer. Brown patch will look as if someone poured hot oil  on the lawn the night before. Within a few days, these areas will die and the infected area will continue to grow in size. Both of  these fungus problems are easy to treat with  a granular fungicide.

St. Augustine performs best when mowed  between 2 and 3 inches. This height of cut should be easily obtained so long as the lawn is smooth. If there are several irregularities in the grade, be careful not to scalp certain  areas. Scalping a lawn could cause damage to the crown of the plant. If the lawn is  uneven, please contact a Carolina Fresh Farms representative for instructions on  topdressing a lawn.



Aeration has two purposes. The first is to simply loosen the soil. The second is to prune the roots. Core aeration is the recommended method and should be performed every 2 years on a typical home lawn during the growing season. If your lawn receives heavy foot traffic, it would be advisable to aerate every year. Aeration should be performed during the growing season.



St. Augustine lawns require 1 to 1 ½ inches of water per week during the growing season. Irrigation of the lawn should be performed in the early hours of the morning just before daylight. This practice will avoid any rapid evaporation of water before it reaches the lawn; yet allow the leaf tissue to dry quickly after the sun rises. Do not water your lawn every morning for short  intervals. This process will only encourage  shallow root growth. Instead, water your lawn for long periods two to three times a week.



A practical understanding of your soil is essential in managing your lawn. Soil pH is perhaps the most crucial element. Most turf grasses perform best when the soil pH falls between 6.3 and 7.0. We recommend that a soil test be performed annually to check the pH values as well as other nutrient levels within the soil profile. Any Carolina Fresh Farms Turf Center will be happy to send your soil samples to our soil testing laboratory.  Our soil testing program is a free service.
