Ridding my lawn of Bermuda

I have a portion of my lawn in Bermuda and I want to kill it off , replace it with something else .

Besides treating with glyphosate , because it will start to come back.

I mean , there's more to it than spraying it , right ??

Thanks

I'm not understanding your question.

If you kill it.....it's dead. THAT grass won't come back.

Is treating it with glyphosate all I need to do ?
Just once ?
Then I can reseed ?

No, it will take 2-3 applications here and then you may still have the occasional sprig pop up. Here is my method.
  1. Water and fertilize, get it very tall lots of foliage to absorb the glyphos
  2. 2 weeks later spray glyphos, two days later resume water schedule 3 times a week put down 1/2 to 3/4 inch per cycle.
  3. 2 weeks after that another application of glyphos, to any green that pops up. Two days later resume water schedule 3 times a week.
  4. One week later scalp and verticut and fertilize and continue water cycle
  5. Wait 2 more weeks and spray anything green that pops up
That should do it, I just use 21-0-0 to fertilize. That should exhaust the starches in the root system and any thatch, besides the mechanical removal of thatch with the verti cutter.

Why not just mix ammonium sulfate into your gly. mix?

It would save you money on water and fertilizer.

No it would not. The whole point of what he is doing is to force the bermuda into growing so it can be killed. What would kill the bermuda in one application is just about illegal in residential areas. I am talking about fumigation with Basamid or Vapam. You cannot apply those products within several hundred feet of structures occupied by people. Gassing the lawn for a one shot kill would mean putting up the whole neighborhood in a Holiday Inn for the week.

Soil Solarization

There are trees in the area and did not wnat to chance of damaging them .

AS is a water conditioner to reduce the interference of hard water and alkalinity with glyphosate. The same effect can be had from proprietary surfactants that contain acidifying and mineral sequestering agents.

AS will also "trick" a non-feeding plant into thinking it's time to feed, again. I mix it in all my gly. apps., this time of year (for that reason, alone). Yes, it is a hard-water ad-mixture. But, it has the residual efficacy I mention above, as a bonus. I've done tests with and without......using several different water sources.

If you haven't tried it, I'm just making a suggestion.
