Summary of the Video About Gray Leaf Spot
Gray leaf spot is an issue with the Saint Augustine grasses in general. It appears as little brown freckles on the green leaf of grass. That’s the first sign of the problem.
It’s not predominant in the Palmetto Saint Augustine, but because Palmetto Saint Augustine is usually put in the shade, that grass variety is often affected. Gray leaf spot is a fungus and since grass in shade may never really dry out, it’s often at risk.
The gray leaf spot develops with excessive nitrogen and excessive moisture, and then if you install grass sod in the shade, those are really good conditions for creating that fungus. It’s usually a June, July, and August, problem. Because the fungus has to have the heat as well. So you’ve got to be careful about watching for gray leaf spot when you lay new grass and you water it excessively. You have no choice but to water it excessively during the first week or two.
When you do that, you create conditions for gray leaf spot. And if you’re in the shade, like with a Palmetto St Augustine, it can, it can really be an issue.
Houston Grass now carries products that are very effective in treating gray leaf spot. The Nitro Phos Eagle Turf fungicide is very effective.
It’s something to be aware of it. You have no choice but to water that grass in thoroughly. When you lay it that first week, and especially in the first two weeks, it stays pretty damp.
I have found though that once you start backing off of watering, after two weeks, if the grass is out in the sun the grass will dry out. The sun will kill that fungus and it takes care of itself. However, if you’re up under the trees, it can be a bigger problem. So anyways, that’s something to keep in mind.
