Fertilizing Your Lawn

Proper fertilization is necessary to produce a healthy, high-quality, attractive lawn.

Hot Springs, Ark. – Proper fertilization is necessary to produce a healthy, high-quality, attractive lawn.  The first step in fertilizing your home lawn is to obtain a soil test before applying any nutrients.  A soil test provides key information including soil pH, potassium and phosphorus levels.  Soil testing is free through county Cooperative Extension Service offices. 

Collect soil samples in a bucket from the upper 4 to 6 inches of soil from ten or more locations around the lawn. Remove any vegetative material such as stems and leaves and air dry and mix the samples thoroughly.  Take about 1 pint of the mixture to your county Extension office for analysis.  Soil can be sampled any time of the year, but sampling lawns in late fall or winter will make sure the results will be available before fertilizer is needed in the spring. 

Calculating Your Lawn Area

The next key step in fertilizing your lawn is to determine the size.  This will aid in calculating how much fertilizer and other materials you will need to maintain your lawn.  The best way to do this is to divide your lawn into several squares, rectangles or circles.  Calculate the area of these smaller shapes and then add them together to determine the total size of the lawn. 

The Fertilizer Label

The two most important pieces of information on the fertilizer label are the analysis and the type(s) of nitrogen fertilizer. The fertilizer analysis is a series of three numbers which provides information on the three most important nutrients for plant growth (nitrogen, phosphorus and potassium).  The numbers in the fertilizer analysis express the nutrients as the percentage N, available P2O5 and soluble K2O. 

Fertilizer Recommendations

The amount of nitrogen fertilizer required by turf depends on species and various management and environmental/management factors.  Never apply more than 1.0 lb N/1,000 ft2 in any one application unless 50 percent or more of the nitrogen is slow-release.  Do not apply fertilizer more frequently than once monthly unless you are establishing a new lawn. 

The timing of N fertilizer applications depends on the lawn species.  Warm-season turfgrasses such as bermudagrass, St. Augustinegrass and zoysiagrass should be fertilized in the summer months when they are actively growing.  Cool-season turfgrass species such as tall fescue should be fertilized mainly in the autumn.  A fertilization in September, November and an application in the spring after the flush of growth (April or May) will result in a healthy turf.  Avoid fertilizing tall fescue in the summer months because of increased risk of the disease brown patch.  Lawns damaged during summer months and newly seeded lawns may need an additional N fertilizer application in October to help with recovery and establishment.  Regardless of species, turf should only be fertilized when it is actively growing.  Therefore, do not fertilize lawns during winter months on warmseason turf and during drought with any species.
