re: Msm Turf questions

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.
