Help 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 MoreSt Augustine in South Florida leafs turning yellow
Comments (1)I'm guessing that you are watering too frequently, possibly daily, which has led to the lawn developing a fungal disease. Notice that there is a distinct arc to the brown blades from the bottom right of the picture to the middle left...that is another clue that it's a fungal disease and not caterpillars (worms). Quite often a fungal disease will form a near perfect circle. Can you post another picture? Get about 3 inches away from some of the grass at the edge of the brown area. The best pictures are taken on a cloudy day or in the shade to reduce the contrast. Fungal diseases show up on the blades of grass. If it is a fungal disease, my recommendation would be to apply ordinary corn meal at a rate of 20 pounds per 1,000 square feet. Corn meal attracts a predatory fungus which feeds on the disease fungus. It goes to work immediately but it takes about 3 weeks to see the improvement as the green grass returns. I have used corn meal successfully every year since 2002 to eradicate disease in my St Aug. Although, now that I have Floratam in the back yard, the grass fights off the disease faster than it can spread. I still see signs of disease...and then it's gone. If you don't have Floratam now, you might consider putting down one flat of it and letting it spread into the lawn. If you had Floratam in the lawn currently, it would be spreading into the thin (brown) areas and taking over even while the disease is present. Cool stuff. Oh and as to the watering, this time of year you should be watering no more frequently than once every 2 weeks in your area. If you get high temps in the 70s, then you could back off to once every 3 weeks. If you are not doing that, please write back and tell us what you are doing so we can get you backed off to watering less often....See MoreBrown Spots in St Augustine (Palmetto) grass
Comments (3)Wish I had more info for you since your plan sounds much better than a toxic, chemical lawn. I used to be more into grass/mowing in OH, but as hot as it is here, I just don't want to mow any more than necessary, no idea how to cultivate the grass here on purpose. And even right after mowing, it's not comfortable on bare feet, blah. We cut it as low as possible, as rarely as possible, and rejoice when drought or cold makes it stop for a while. I'm hope someone who appreciates fertilizing/cultivating grass will pop by with something actually helpful to answer your questions. Good luck!...See MoreSt. Augustine Grass, First Time Home Owner, Please Help :'-(
Comments (19)We had scotts lawn service come out and they've treated the lawn for weeds twice, fertilized twice and aerated the lawn. However prior to doing any of that, the lawn still looked exactly as it does in my pictures. We've also had 10+ inches of rainfall and it continues to rain all this week. They mentioned no sign of chinch bugs or disease. Perhaps I should check the pH and apply Lime if necessary? This post was edited by VinceFLA904 on Wed, May 22, 13 at 17:12...See Moredfedele84
