an herbicide called cimarron by Dow kills bahia. good luck.
I think it's actually Bahia.. I have for years thought people were saying Mahayana or Maheya. Recently I found out it was actually Bahia grass. Google that and you will find your answer. :)
It should blend in with it :)
Yes. Products containing Atrizine should not be used on Bahia Grass.
There is not really any weed control out there that will kill one type of grass and not the other. If you want to get rid of Bahia grass in St. Augustine, you best bet is to spray the areas of Bahia grass with Roundup (the ready to use kind with the blue sprayer). Avoid as much of the St. Augustine as you can as Roundup is non selective, and then in the bare areas left by the dead Bahia grass you can put new St. Augustine in 7 days later. If the bare areas left are not too large, you can fertilize the St. Augustine encouraging it to spread into the bare areas.
Fire (never recommended) would destroy any grass above ground but would have no effect on its root system. Bahia grass grows best in sandy or dry soil, which is why it's so popular in sandy coastal regions. One of the surest ways to kill bahia grass is to drown it by keeping the soil consistently moist until it dies back.
The growth habit of bahiagrass is having sandy soils with a pH of 5.5 to 6.5. This grass has deep roots.
There are several grasses that can grow in low rainfall climates. The examples are Bermuda grass, Zoysia grass, Buffalo grass, St. Augustine grass, Fescues and Bahia grass.
According to the Feed Table link below, Bahia grass hay has a CP (crude protein) percentage of 6% and a UIP (Undegradable Intake Protein) of 37%. Bermudagrass coastal hay, on the other hand, as CP% of 10% and UIP of 20%; Bermudagrass Hay has 10% CP and 18% UIP. So, in summary, Bermuda has a higher protein percentage than Bahia, however as far as bypass protein is concerned, Bahia is higher. See the Understanding Feed Analysis link below for more on how to interpret the feed table.
Saint Augustine is the best grass for Florida, but you can't seed for it. You have to either use plugs or lay sod. Bahia will grow from seeds, but it sprouts really fast and then splits into stalks at the top within the week. You actually have to mow more than once a week with Bahia.
St. Augustine grass is good for horses, but it doesn't repopulate very quickly. The best option for horses is Tifton 9 Bahia.
There are many products that can help you replace the nutrients that the grass is losing and causing yellow spots. You can also rip up the yellow grass and put down grass seed.
