St Augustine showing spots/patches of yellow
Comments (1)Here is the image with the larger patches and the orange flags mentioned. Thanks!...See MoreHelp with St, Augustine grass please?
Comments (5)I suggest waiting for the weeds to be in full vigor. Fertilize now with an organic fertilizer (alfalfa pellets (rabbit chow) are good). App rate is 20 pounds per 1,000 square feet. Then in two weeks spray with this stuff... This is some bad stuff, but it's the only thing that will flat wipe out the weeds and not kill off the St Aug. Just spot spray the weeds. Don't spray the entire yard. But do get all the weeds. That's why I suggest fertilizing first to get them all healthy and ready for death. They will not die right away. It will seem like the stuff didn't work, and then, SUDDENLY, all the weeds will be gone. You can only spray that stuff once per year. Even if you spray it again it doesn't seem to do anything, so make the most of it....See MoreYellowish spots on St. Augustine Grass
Comments (14)hgiljr, I have a contact in Margate and I am told that the rainfall alone is quite sufficient to keep the grass growing well there; your comment about mowing reinforces this and I would not worry too much about watering. As for inorganic feritilizing, I think that the timing is too late; there is too much rain. Apply 'Milorganite' or similar product. The temperature is right and these products will not leach away. And lest I forget, the yellow spots might be the beginning of a fungus infection. If the spots become outlined by a brown margin in the shape of an hourglass, that will confirm it. Again the temperature and (over?)watering can contribute to fungi growth at this time. Keep a close watch on the area. If it spreads wider or gets more intense in the same area, you might want to treat it. Accurate diagnosis is ESSENTIAL....See MoreGray leaf spot in St Augustine grass
Comments (3)Someone elses idea's if you want to use chemicals. Provided a link below. http://en.allexperts.com/q/Lawns-725/St-Augustine-lawn-2.htm My Experience I have not used any treatments (bug / 'cides) for my grass in probably 2 years now. This summer I watched ALL of my neighbors grass get brown patches and so forth. I did not have a problem for the last 2 years. I water in the mornings twice a week and fertilize (less then stated amounts) 3 times a year. If I find an area that looks like it is getting in trouble I will throw compost on it (Example cow manure compost). I have always noticed the ULTRA-GREEN lawns are the fist to die in the summers. My point is the more chemicals you add to the lawn, the more problems it seems people get. I would either dig it up and replace if it is small, or maybe try some compost and treat the soil. Healthy grass will creep in. This has been my experience. And though there is some weeds (the grass keeps it in check - most weeds in your lawn are from poor soil / severe dry conditions), it is one of the best looking lawns in the neighborhood. Adding fertlizer would be a bad choice at this time, could further the problem, go compost or replace. Here is a link that might be useful: Could help...See Moredfedele84
