Gray leaf spot is a fungus disease that affects several turfgrasses. It is a mainly a problem on St. Augustinegrass and perennial ryegrass. Hot humid summer weather and high nitrogen levels can make turf susceptible to this disease.
Occasionally turfgrass begins to thin and moss and algae begin to grow. These primitive plants develop because conditions for growing dense, healthy turf have declined. Neither moss nor algae are thought to be parasitic and both are spread by wind blown spores. Moss and algae can both form crusts on the soil surface which reduces air and water movement into the soil. Factors that favor the development of moss and algae include wet and humid conditions and compacted soils with thin turf.
We've received several calls this week from homeowners and landscapers with questions about their warm-season turf lawns. Many are concerned that their lawn has been a victim of
The introduction of new turf herbicides will continue to enable practitioners to control troublesome weeds. In 2010, turf managers will see several new options for weed control from novel active ingredients, combination products, and label amendments. The following article contains an unbiased view on these products and discusses efficacy for turfgrass weed control.

Often one of our biggest problems in the spring is fertilizing turf too early. Early application of fertilizer can lead to early green up. Though this may please the client, turf that greens up early can be more susceptible to damage by late cold weather. Early fertilization may predispose the turf to disease problems. Also, nitrogen applied too early may not be taken up by plant roots which are still dormant. This nitrogen can be lost by leaching and runoff.
Florida betony or rattlesnake weed (Stachys floridana) is a problem weed in both turf and ornamentals. Florida betony or rattlesnake weed is a “winter” perennial. Florida betony is dormant during the hot, humid summers of the South. In most of Georgia, Florida betony growth begins in early to mid fall, slows in the extreme cold of winter, and continues until late spring.
Just like trees, shrubs, pets and even humans, turf grasses need water to survive. The perception that turf is a water consumer is correct, but we're all water consumers.
The forgotten benefits
Moving affects the overall quality of turfgrass. Mowing affects a turf's density, texture, color and uniformity. Even if you water and fertilize your lawn correctly, its overall quality is compromised if you don't mow it properly.
Mowing Heights and Frequencies
Different turfgrasses require different mowing heights:
Shade is a wonderful benefit of trees but a major challenge for growing turfgrass. Although growing grass under trees is difficult, there are some important tree and turfgrass management principles involved in successful coexistence.
