Will St. Augustine grass plugs overtake Bermuda?

I just always liked st aug grass.

The Bermuda tends to die real easy when it isn't watered and their is a period of no rain. We had several sections go brown this summer

Yep, it will take approximately forever in my experience. Water very well. In cutting season, cut very high. Fertilize well also/

You will always have a mix. U can never truly get rid of bermuda without killing st Aug

Just watch it to make sure the bermuda doesn't get too thick around the St.Aug and allow the St Aug to grow tall as it wants and seed itself and make runners,do not cut it. This time of the year i would not worry too much, it will get cold soon and the Bermuda will die back, and u need the bermuda there now to hold the soil in place.This spring i would buy some sod, it will take much better,don't go the cheap route it will just piss you off in the end

It is not that expensive to buy the sod and lay it yourself. Maybe a grand depending on the size of yard.

A lot of factors come into play.

Which variety of each grass type?
How much sun/shade.
How much moisture does your yard get?
What is the soil type?
How tall do you allow the grass to grow before mowing?
etc, etc...

I have patches of centipede, st aug and Bermuda in my yard. Would prefer the centipede but following years of attempts to engineer the turf I've decided to step back and allow each variety to occupy the spaces it likes.

Had to chime in - Ive been a golf course supt for almost ten years. Since my Aggies sucked this weekend I might as well talk about something...Don't know everything but here is a couple of facts:

- no spray will kill only bermuda in a st.augustine mix.
- "plugging" any grass at six foot intervals will take forever to spread even if the plugged grass is somewhat better suited
- bermudagrass is extremely difficult to completely remove. The best herbicide combination that I have seen is repeated applications of roundup combined with fusillade sprayed at the appropriate rates, intervals, and time of year. Even after all this bermuda can either come back or be tracked back in. Soil sterilants and fumigants are more effective, but difficult, expensive, and many times unavailable to apply. Both of the above are non selective and will kill everything in the application area. See this article from some other SEC schools for more info

-in my opinion the only way you will not have a mix is if the area has a ton of shade. St.augustine does much better in the shade and thus will be the more aggressive plant in that situation. Too much shade and neither will grow.
- watering and higher mowing height will favor st. Augustine in most situations. Too much water in spring and fall and st Augustine more susceptible to disease such as brown patch.
- drier conditions and lower mowing height will favor the bermuda in most situations.

I have mix in my un-irrigated yard. With all the droughts bermuda has taken over in a lot of spots. I like bermuda better as it is more tolerant of herbicides, has better drought hardiness, and is more disease resistant in my climate.

Just my two cents.....

Here's the front yard. Bermuda kinda turning brown when I cut it shorter.

(I let it get too long now I have bails of hay )

Considering I only put fist sized plugs staggered, it seems to be spreading well.
