MSM Turf and Temperature
Posted on 7/21/25 at 5:36 pm

Quick question regarding MSM Turf. The temperature starts around 76 and gets up to about 95 this week. I know it is recommended to use when the temperature does not exceed 85 degrees. Does this mean at the time of application, or daytime temperature? I'm trying to see if I'd be good to spray this early morning or late evening. Thanks for the input!

I don’t know the answer for sure, but I have no issues spot treating the yard in the evening. I don’t spray the entire yard though just in case.

Unfortunately the entire yard needs treated due to the previous owners neglecting it. It’s a mix of st aug, Bermuda, Virginia buttonweed, and lots of other weeds. The lawn is lush and green so it doesn’t appear stressed at all.

identify what weeds you have 1st of all MSM for the buttonweed i always went a little on the heavy side of the recommended dosage, always use a surfactant, with it,you may get some yellowing, but its temporary, probly got a lot of Nutsedge, I use dismiss for nutsedge and kyllinga works fast.
got to apply good pre emergents in fall and spring. I use Prodiamine and Specticle flow
got to stay on top of it

I have a section around 400 sq feet of torpedo grass really starting to take over so yesterday I just nuked it with some glyphosate. I’m going to start over in that section after it’s dead. My plan is to till the section to turn over the soil and river sand that was brought there three summers ago then plant some st Augustine sod/plugs. This fall im going to get serious about applying pre-emergent to the entire lawn and hopefully get some areas of crabgrass and nutsedge under control next year.
I’ve used MSM Turf before but I mixed it too strong and killed a lot of the St. Augustine accidentally. It’s good for weeds as long as you mix it to the right strength, though. I really like Sedgehammer for nutsedge and Celsius for Virginia buttonweed.

I don't know of a pre-emergent that works for nutsedge.

I find Celsius works well for VBW but MSM Turf works great on it too.

I’m not a fan of st aug, but the yard is mostly that and it’s lush, thick, and green. I’ll work with it to see how good I can get it. But if I accidentally kill it, I won’t miss it. It would give me an excuse to regrade the yard and put a zoysia or Bermuda lawn in.

This year I have come to the opinion that MSM beats Celsius on VBW. MSM also seems to ding my Bermuda less than Celsius in the hot temps. I also have doveweed, so I’m still using some Celsius.

I know it's been SUPER HOT the past few days but Celsius burned my Bermuda badly (granted it was medium rate and applied on the hottest part of the day) a few days ago. I was very surprised as it's never done that before.
I've found if you hit VBW early enough (young plant) and not when it's mature and spreading like crazy, Celsius is effective. But once it's sort of established and more mature, I will always go for MSM. I try to be diligent and get all weeds early though.

I would start small and work my way up.
1/16 tsp per gallon of water per 1,000 sq ft *without* a surfactant.
And yes, I would spray at 7:30 PM.
See what that does.

Before spraying, I walked my driveway and sprayed 1,000 square feet to self-calibrate how much water it takes me with my walking speed and spraying pattern. It came in right at 1 gallon per 1,000 square feet so that's what I went off of.

If mine weren’t Bermuda I’d have zoysia I live in the house i grew up in and dad put this strain of Bermuda in in 1965

quote:I get it. He spot treats the weeds he sees instead of spraying the entire yard, just in case. I just didn't have that option because the weeds are completely intermingled with the grass. But, if I nuke the grass, that gives me an excuse to splurge and get the lawn exactly how I want it.

I hate to break it to you but one application of glyphosate isn’t going to kill the torpedo, only burn it back. There is a ton of carbohydrate storage in those roots. If you till before the roots are dead you are going to actually make your situation worse in the long run. You can spray RoundUp several,times over the course of a couple months and you may get most of it. Sometimes covering the ground with black plastic in between applications helps. You are trying to stop photosynthesis and kill out all the roots but it takes a lot of time, unfortunately
