The Floratam variety of St Augustine was developed in Florida and Texas to address the issues of both states. The one fault it has it cold tolerance; however, in actual use it seems to survive as far north as Dallas with little problem. Now if you have several days straight with high temps below 20 degrees, then you might have a problem. I doubt you see that in southern Alabama. They only see it in Dallas once every 10 or 20 years. Floratam loves full sun. I have it in heavy shade under a giant live oak, and it survives, but it is not exactly dominating. I also have it in half day full sun and it is amazing. Floratam was selected for disease resistance. Here is the thing about disease in St Augustine: I can induce a disease in any St Aug by covering it up with something like cardboard or anything that covers it like a blanket. My wife likes to throw garden clippings out onto the grass. If I don't watch her and clean it up, a disease will start after about 3 days. That used to be horrible before I discovered corn meal. I put sod after sod on the same diseased soil and watched the new sod die before it rooted. After corn meal I have not had that problem since. So in order to prevent the disease you have to water it properly (see below) and never let anything blanket it and cut off the fresh air. Watering is important for proper root development, weed control, and disease control. All lawns should be watered in the same way. The mantra is deep and infrequent. Deep means one full inch applied all at one time. Infrequent means allow the soil surface to dry out completely to the point where the grass is almost wilting before you water. When this happens depends on YOUR situation regarding temperature, wind, humidity, soil type, shade, cloudy days, grass type, mowing height, and a few other criteria. But in a practical sense, the advice is not much different between Vermont and Phoenix and Orlando. In general... with temperatures in the 100s or above, water once every 5 days. With temps in the 90s, water once every 7 days. With temps in the 80s, water once every two weeks. With temps in the 70s, water once every 3 weeks. With temps in the 60s and below, water once a month. If you have full shade like I do in San Antonio, I still water once a week in the heat of summer, but I only water 0.3 to 0.5 inches instead of a full inch. If I lived in Las Vegas in the summer, I would water 1.5 inches once very 5 days. Mow St Augustine at your mower's highest setting - always. There is never any reason to lower it for St Aug. Tall grass uses much less water than short grass. Tall grass grows much deeper roots than short grass. Those deep roots will be able to pull water from deeper in the soil structure from that rain that came by 3 weeks ago. In order to demonstrate that tall St Aug needs less water, I am doing an experiment in George West, Texas on the edge of the Texas desert. I have not mowed parts of my lawn since October of 2011. 2011 was a moist year but 2012 and 2013 were both very dry years. There is one area in the shade of an oak and my house which has not been artificially watered once since then, and the grass looks great. I don't recommend you let your grass grow up to 32 inches high, but it can and will survive nicely if you do. In San Antonio I mow St Aug at the highest setting every 2-3 weeks. The last thing I do and have done since 2002 is use only organic fertilizer. I started using corn meal back then and have moved up to a little higher performance with alfalfa pellets (rabbit chow). The biggest advantage I see for using these materials is the improvement to the health of the soil. When I was using chemical fertilizers it seemed that sometimes the fertilizer didn't work. Of course with chemical ferts you can't just reapply right away, so the next time I fertilized I applied it heavier. That seemed to work, but I was on a see-saw with the fertilizer. Once I went to organics, it always worked. With organics, if you missed a spot or are not happy with the results, you can reapply right away if you want to and not fear damaging the grass. One of the gurus on another forum experimented with extremely heavy doses of soybean meal and Milorganite. He applied both at a rate of 50 pounds per 1,000 square feet every weekend all through the growing season. Here is a picture of his lawn taken in the summer of 2011. All the other lawns in that picture were the original builder grade Kentucky bluegrass, but his is an improved variety. But if he was not taking proper care, his would look just like theirs. He lives in eastern Pennsylvania and does all the things I suggested above for caring for St Augustine. But he was also overdosing on organic fertilizer. But back to you - St Aug can be fertilized 3x per year with organics. I prefer 5x per year on Washington's Birthday, Memorial Day, 4th of July, Labor Day, and Thanksgiving. These dates would work for you, too. I use them because they are easy to remember and I'm always home. St Aug wears fairly well in that it can recover from some trampling. We have a new puppy and he has worn a path in the grass leading to our side yard. I am confident that he'll settle down someday and the grass will return. Bermuda and St Augustine are both good about refilling after wear. Now having given you the sales pitch for St Augustine, bermuda, specifically hybrid bermuda, makes a good lawn, but it is a higher maintenance turf than St Aug. Bermuda needs to be mowed 2x per week and fertilized heavily once a month if you want to to look nice and have minimal weeds. If you prefer low maintenance, then St Aug should be lower maintenance for you. I used to have an annual conference in Mobile and Pensacola and found the St Aug lawns to be beautiful. I did not see a disease problem, although I wasn't looking for that specifically. I realize you are spooked by your father's lawn, but give the corn meal a try and see how that works. You have time to wait for that to clear up. Apply the corn meal now and check back again on the 4th of July. I suspect he'll notice the improvement by then. You should not have to live in fear of a St Aug lawn. I have been there, but since I have discovered the corn meal "trick", I obviously fully embrace it now.

crikey ... do not attempt to burn new seedlings... i dont care what formula .... i have never seeded a part of my lawn.. when i did not 'expect' .. to have to reseed spots for a few years.. you have extremely high 'expectations' of the process ....germination ... vermon.. weather.. etc ... if you wanted sod like results inside two years.. you should have sodded .. if you set aside your 'expectations' ... you are probably doing good.. considering the timing and all ... pix might change this comment ... that said... early fall.. is seeding time.. days warm enough to germinate.. and cool nights for recovery from a warm day ... in my MI.. i would be setting down some seed in late august.. so that by the time it germinates inside 2 weeks... its prime grass season ... you have to adjust that for your area.. though it cant be all that different ..... water as best you can for the next two months... start bringing it down to about 3 inches... a little at a time... individual plants will start multiplying... and then just lightly rake the soil.... and seed the bare patches ... i would wait to fert until next spring .... its not really a food issue at this point ... IMHO ... at this time of year.. its water.. water.. water .... have you talked with the guy who put it down??? .. can he get you some matching seed??? ken

It is unfortunate that misinformation continues to be repeated about glyphosate. Denmark has not banned glyphosate, nor have "many European countries". Denmark at one point thought that some of the monitoring they were doing showed that glyphosate could move into agricultural field drainage water in autumn but once they looked at their data and related it to the methodology they used, they enacted no ban whatsoever. As the Danish Environmental Protection Agency specifically stated: http://www.egeis.org/home/main/Evaluation-GlyphosateDEPA.PDF "Against this background, the Danish Environmental Protection Agency believes that no unacceptable risk of pollution of the groundwater is associated with the currently approved agricultural use of glyphosate. The Agency thus does not consider that the updated state of our knowledge provides any technical grounds for the imposition of restrictions on the autumn application of glyphosate." Used properly, glyphosate will not pollute drinking water nor will it have adverse effects on humans. Once applied, it binds tightly to soil particles and is not herbicidally active. If it is applied to hard surfaces such as sidewalks it can move offsite of course. It can also move if there is active soil erosion carrying soil off site. It is of very low toxicity, and breaks down completely into natural constituents over time. It is of equal or lower toxicity than most household products such as detergent, soaps, shampoos, cleaners etc. and far less toxic than some of the "alternatives" often discussed such as bleach, kerosene, high strength vinegars and so on. There is so much misinformation being repeated on the web that it is difficult to get reliable information. This link provides an published overview of the available literature.

I had the same problem! Here's what's happening. Decomposing wood is zapping nitrogen from the soil.. Hence yellow grass.. ( your not gonna like this next step) get a wheel barrow. And a shovel dig up all the decomposed wood chips. This sucks I know! After 5 loads of debris and wood chips I added a nursery blend of mix. High quality. Don't skimp here. Build it back up re seed and apply some Alfa meal on top. Then "sling" with a large manure shovel the mix on top of the wet seed to create a thin layer so the seed will have cover and help with moisture retention. worked wonders for my lawn before.. Notice white spots where tree was After Reno
