Environmental Stresses and Your Florida Lawn

Figure 1. A lawn showing nitrogen deficiency symptoms.
Florida lawns are subject to many environmental stresses. These can include nutrient deficiency, salinity, temperature extremes, over- or under-watering, soil problems, and prolonged exposure to shade or traffic. The use of proper cultural practices will help keep your lawn healthy and more stress-tolerant. This two-page fact sheet explains how to choose the most appropriate grass, fertilize properly, mow to the correct height, and irrigate for your lawn’s needs. Written by L.E. Trenholm, and published by the Environmental Horticulture Department.

General Recommendations for Fertilization of Turfgrasses on Florida Soils

gator head on lawn
In many neighborhoods, people envy the individual with the most beautiful lawn and think they cannot grow a lawn of equal quality. That is not necessarily true. A well-maintained lawn only requires some knowledge about fertilization, watering, pest control, and mowing. This publication provides basic information about fertilization. By far, the best approach to a proper fertilization program is to start with a soil test, but, if a soil test is not available, these guidelines can be used for a general turfgrass fertilization program. Original publication date May 1991. Revised August 2013 and August 2015.

Watering Your Florida Lawn (ENH9/LH025)

 Figure 1.  Leaf blades folded in half lengthwise. Credit: Laurie TrenholmIrrigation is one of the most important cultural practices that we do for our lawns. Since water is a limited resource and is vital to the health of your lawn, it is very important that watering be done correctly. This 3-page fact sheet was written by L. E. Trenholm, J. B. Unruh, and J. L. Cisar, and published by the UF Department of Environmental Horticulture, April 2013.

Zoysiagrass for Florida Lawns (ENH11/LH011)

Zoysiagrass maintenance is different from that of other Florida lawn grasses. When improper maintenance practices are followed, undesirable results are likely to occur. Learn the details about this attractive turfgrass that has been dramatically improved by turfgrass breeders in recent years. This 8-page fact sheet was written by J. Bryan Unruh, L. E. Trenholm, and J. L. Cisar, and published by the UF Department of Environmental Horticulture, June 2011.

Centipedegrass for Florida Lawns (ENH8/LH009)

Centipedegrass is a slow-growing grass with low fertility requirements when compared to other Florida lawn grasses. It grows close to the ground, is medium textured, and is naturally lighter in color than other lawn grasses. Well-adapted to the climate and soils of Central and Northern Florida, it is the most common home lawn grass in the Florida Panhandle. There is now one cultivar adapted to South Florida conditions. This 7-page fact sheet discusses the advantages and disadvantages of this turfgrass variety, cultivars available for lawn use in Florida, establishment, maintenance, pest management, and other problems. Written by J. B. Unruh, L. E. Trenholm, and J. L. Cisar, and published by the UF Department of Environmental Horticulture, April 2011.

St. Augustinegrass for Florida Lawns (ENH5/LH010)

St. Augustinegrass is widely adapted to the warm, humid (subtropical) regions of the world. It is the most commonly used lawn grass throughout the state of Florida and can grow satisfactorily in a wide variety of soils. This revised 11-page fact sheet discusses the advantages and disadvantages of this turfgrass variety, cultivars available for lawn use in Florida, establishment, maintenance, pest management, and other problems. Written by L. E. Trenholm, J. L. Cisar, and J. B. Unruh, and published by the UF Department of Environmental Horticulture, April 2011.

Bahiagrass for Florida Lawns (ENH6/LH006)

Bahiagrass is a popular, low-maintenance lawn grass that does well with limited water and fertilizer inputs. Although bahiagrass does not produce a carpet-like, dense lawn like some other warm-season lawn grasses, it does provide a good, low-maintenance lawn where slightly reduced visual quality is acceptable. This revised 7-page fact sheet was written by L. E. Trenholm, J. L. Cisar, and J. B. Unruh, and published by the UF Department of Environmental Horticulture,April 2011.

Bermudagrass for Florida Lawns (ENH19/LH007)

Bermudagrasses (Cynodon spp.) are among the most widely used warm-season grasses. Improved, fine-textured bermudagrasses are used throughout the south on golf courses, athletic fields, and in high-profile residential and commercial landscapes where a fine-textured, dense ground cover is desired. This revised 5-page fact sheet describes advantages, disadvantages, cultivars, maintenance, and pest problems. Written by L. E. Trenholm, J. L. Cisar, J. B. Unruh, and published by the UF Department of Environmental Horticulture, March 2011.

Brown Patch (SSPLP5/LH044)

Brown patch, large patch, or Rhizoctonia blight is a fungal disease observed November through May that infects the leaf area closest to the soil, eventually killing the leaf.

Take-all Root Rot (SSPLP16/LH079)

Take-all root rot, or Bermudagrass decline, is a root rot disease triggered by high rainfall or stress and manifesting as irregular yellow or light green patches two to three weekds after the pathogen has been active in the roots. This 3-page fact sheet was written by M. L. Elliott and P. F. Harmon and published by the UF Department of Plant Pathology, February 2011.

Turfgrass Disease Management (SSPLP14/LH040)

Turfgrass diseases are underappreciated because the biological organisms (plant pathogens) causing the problems are rarely observed. Fortunately, grasses maintained using proper cultural practices (water, mowing, and fertility) are not as likely to become diseased or be as severely damaged as grasses that do not receive proper care. This 11-page fact sheet discusses turfgrass diseases, their causal agents, diagnosis, and management. Written by M. L. Elliott and P. F. Harmon and published by the UF Department of Plant Pathology, February 2011.
