My Florida St. Augustine had gray leaf spot. I’ve treated for fungus, and applied liquid iron, and the lawn is starting to grow out of it. Question: I usually mow my lawn at 4″. During this time of recovery, should the lawn be mowed lower to help keep it more dry between the blades of grass?

Yes!Gray Leaf Spot(GLS) is the only disease that mowing the turf shorter will help recovery. We are so used to leaving the turf grow to ease recovery that once GLS came along alot of the old rules were rewritten. Did you use any fungicides on it?
Good Luck……………….

Yes. I used a fungicide about two weeks ago. I am planning to retreat again this week. Much of the lawn looks greener, but a few areas look like they could use another treatment, so I’m going to hit the whole thing again. If it would just quit raining every day it sure would help!

I used corn meal and GLS went away just fine without killing all the benefical fungi.

Forget the cornmeal unless you are baking some cornbread. Apply (COMPASS) at a rate of 0.15-0.2 ozs./1000 sq. ft. Wait 14 days and apply another application if necessary. This will take care of your (Gray Leaf Spot)

QWERTY- I have a question. If you use the cornmeal like you say- how did you get GLS in the first place?
