So I guess you got the message somehow that cold weather will not defeat bermuda. Hope so because I'm sure that's what everyone meant to say. I almost hate to say this but bermuda is easily killed...without chemicals. If you live in the south and have St Augustine, all you have to do is make sure you water the St Aug and mow at the mower's highest setting. The bermuda should die out in a season or two. One of my neighbors (I can hear the groans) planted a yard full of bermuda sod next to his neighbor's St Aug. Within two years the St Aug had taken over about 20 feet into the bermuda. If you have fescue, all I can suggest is to plant as many fescue seeds as you can to try to make it more dense with your preferred grass. I'm experimenting with a type of shade tolerant zoysia that may choke out bermuda. The zoysia is very aggressive - in fact every bit as aggressive as bermuda. Last year the zoysia was just getting established in the area where I killed some bermuda (see below). This year I'll let them run wild and see what happens. I also killed an area of bermuda about 20x20 last year. I covered it with several inches of sand and several inches of mulch. There were less than a handful of bermuda sprigs that made it to the top. Except for moving the sand and mulch, that was as easy as it gets. The water advantage bermuda has over St Aug is that when the drought hits, bermuda goes dormant while St Aug goes dead. Once the rains or irrigation comes back, the bermuda will survive while the St Aug does not. So they say that St Aug takes more water. Otherwise both take the same amount. If you water incorrectly (too frequently) neither grass will do well. Bermuda is both aggressive and persistent. St Aug is less aggressive and much less persistent. My wife can clear an area of St Aug and it will remain clear until it reinvades. Bermuda can be cleared and in a week the entire area is fully growing with the persistent pieces left behind. Someone already said something to the effect of live and let live. A weed is an unwanted plant. If YOU want it, it is not a weed. If the OP doesn't want it, then it is a weed for purposes of THIS discussion, no matter how much one person or another likes it. rdaystrom, if you have 3 acres of bermuda, you need to consider converting 2 acres of that into a park for other recreation. Have you ever seen a 3-acre lawn in Better Homes and Gardens? Oops! I just remembered, you can't get rid of bermuda. Just thought I'd fan the flames, heh, heh!

So I have a problem. I re-sodded my yard almost 2 years ago with empire zoysia. I also added two sprinkler heads in the middle of the yard as I thought it was not getting enough water, this was one of the reasons I believe led to the destruction of the last sod and why I had to replace my sod in a two year old home. However I am no irrigation professional and I did not bother to lay cans out to measure how the water dispersed throughout my yard. From my perspective it looks as if the middle of the yard is still not receiving enough H20? I really don't know? At the beginning of the growing season (mid february) I cut my grass to about 2 inches to remove thatch build up! I have been cutting my yard during the growing season at 3 inches. I also fertilized my yard February 22, 2012 with a slow release nitrogen formula (lesco 16-4-8) at a rate of approximately 1.5-2 lbs per 1000 sq. feet. My yard looks great besides the middle section. Also my sprinkler zone in the front yard is a follows; basically the zone is a square. To the street the length =20 feet and from my driveway to the neighbors yard the width = 50 feet. I have 4 inch pop up heads (hunter). 4 each on the width side and 2 each on the length sides and the two i put in the center of the yard! I have not don't a soil sample test yet as I think the problem is with the watering. I just bought a sprinkler last week and placed it in the middle of the yard! I will take some pics tomorrow, any advice would be greatly appreciated!

why don't you ever provide any sources for your statements? Because this website does not require sources in order to post. This is a site to share personal experiences and helpful information we might have picked up elsewhere. I did some checking to see what Jeff Lowenfels had to say about RoundUp. I learned a couple things. One - I had always pronounced glyphosate wrong. Secondly, Lowenfels is an organic purist who hates anything he cannot pronounce. That is very well and good, but what do you use when you want to kill one invasive grass that is heading across the mulch toward the other invasive grass? I suppose on a small scale, you could put a little elbow grease into it and pull the invader out. But I wonder what Lowenfels would suggest to kill a yard full of bermuda, zoysia, or creeping charlie in preparation for a renovation back to a different turfgrass. Also if you want to learn a lot more about RoundUp check the wikipedia page. Then check the wikipedia page for glyphosate.

As long as this discussion has been resurrected - One Yard Revolution did a good video a couple of years ago comparing minerals added to the soil with rock dust versus leaves. Interestingly, the leaves came out on top as the better source of minerals. Which makes sense - the trees roots go down deep and pull up minerals from the soil the end up in the leaves, which are them deposited on the ground. It's nature's way of replenishing those minerals back in the top foot of soil where most biology happens.
