Msm Turf questions

Yes to all, temp and your grasses, and I seem to recall there is a Site One Landscape in the Suburbs of Savannah that should carry it. In Baton Rouge some, but not all, independent retail garden centers carry it as do at least some sod suppliers, and feed & seed type stores often carry it. Maybe a Tractor Supply store? You’d need to check.

I should note if you read the label on MSM Turf it says don’t use at temps above 85 F but I’ve used it a higher temps safely and this was on the advice of horticultural professionals. If you find it, all the application rates will be in oz per acre. So you don’t have to do the math, 1/8 teaspoon or 0.5 grams per gallon + 2 tsp of surfactant for spot spraying will work. Be prepared for a follow up application in 3 weeks. Expect some temporary yellowing of St Aug and centipede but it will recover.

Is this the ratio for a bermuda lawn as well? I have it written on a post-it note somewhere in my shed but who knows if I can find it And I thought re-spraying was more like 6 weeks?

Thanks for the input

Yes - same for Bermudagrass. 3-4 weeks.is the usual norm if a re-spray is required which is usually the case on a perennial. You can double check the label to see - I didn’t see anything mentioned On re-spray interval but I may have missed it - it’s a long label.

Should I use a surfactant to help make sure I apply evenly? I will just be using a cheap two gallon pump sprayer. Just worried I want apply evenly and might over apply. Also is it best to apply in the morning or evening?

Well I feel dumb. I was under the impression that it had a coloring agent so you could see where you sprayed that would go away after drying.

Marking dye is really a pain in the butt.

Any tips on applying evenly.?

Most seem to recommend using a backpack sprayer with the fan tip. Does your current sprayer have a fan tip?

Sounds like you’ll be spraying the entire lawn vs spot spraying - correct?

I agree a fan tip is desirable for entire lawn spraying but your ortho sprayer doesn’t likely have one, but down the road you can look at purchasing a another sprayer with interchangeable spray tips, whether hand held or backpack. FWIW, I’ve settled on Solo brand sprayers and been happy with them.

To avoid over or under spraying you need to “calibrate” your sprayer. You are going to apply the targeted amount of MSM Turf (by state) over 1000 sq ft of lawn. Think of the water in the sprayer is only a carrier, not a dilutant, so you can use 1 or 2 gallon of water in the sprayer, with the herbicide and spray that evenly over 1000 sq ft of lawn.

To “calibrate” your sprayer, mark off 1000 sq ft in your driveway. Put 1 or 2 gal of water in the sprayer, then start spraying the 1000 sq ft. If you empty the sprayer of water before you completely spray the 1000 sq ft. you are over spraying and need to pick up your space while walking, if you have water remaining in the sprayer after spraying 1000 sq ft you are under spraying and need to slow your pace of walking while spraying. So it is a trial and error approach fo zero in on the right technique. I personally find it easier to spray 2 gal of solution vs 1 gal per 1000 sq ft, might be different for you. Use a 1.5 gal if you want.

Once you’ve figured out the right combination for you, mix the MSM Turf in the water and spray the lawn.

Expect some yellowing and reduction in growth of the desirable turf grass after spraying, that’s normal, but it will recover.

Scotts makes a 2 gallon sprayer with a multi-spray tip. The fan setting works well
