OT: St. Augustine

[DEEREdawg]

With the recent Bermuda thread what do y’all do to treat weeds in your St. Augustine?

I would start cutting the St. A atleast 4" tall. That would kill anything trying to grow under it.

I put out weed & feed in the late winter/early spring, then sometimes in the fall. Mow regularly and water if needed, encourage those runners to take off, it will choke out weeds and other grasses.

MSM Turf for broadleaves now, Manage/ Image for nutsedge, Prodiamine and Simazine in September.

Here's a guy that knows a lot about St. Augustine. This video may not address your issue but he has lots of videos that should cover what you want to know. Fairly entertaining guy too.

This one million times. Cut it high.

Cut mine about 3.5 and that keeps the weeds down well for me, mainly because I've got a lot of shade and they don't like that.

Dr. Jeff Krans was one of my turfgrass instructors at MSU way back when. He called St Augustine 60mph grass because "you've got to be driving 60mph when you drive by it in order for it to look good" . I like it though, only problem I ever have is some fungus/mold when we've been getting the rain we've had lately but even then it usually takes care of itself once it warms back up and quits raining.

I see this every year. Homeowner has yard service that won’t raise the mower deck from what they are cutting centipede at. I get calls in spring that St Augustine looks bad. It’s because it was stressed going into dormancy. Winter really weakens it further. Always cut St. Augustine at the highest or close to the highest setting on your mower.

Also I’ve had a battle with chinch bugs in my yard. If you’ve had them once, you’ll have them again more than likely. Remember to put out an insecticide in the spring. Look for imidichloprid as the active ingredient. Good news is this chemical will usually last a calendar year. (Keep it out of your tomatos tho)
