Hey guys I normally cut twice a week and few weeks ago I was out of town for a few days and only got to do my first cut. While out of town it rain the entire time I was gone and my lawn was much longer than I have let it grow all year. Just wonder could that be the cause of the brown spots in lawn? .. This is a Bermuda /Tall fescue mix . I feel I may be cutting all the green off so do I need to drop down a notch to reset my HOC?

To me it doesn't appear that you're dealing with brown patch; your last sentence might be the most sensible approach. Since the areas are all over the yard, and not clustered up and spreading, I'd say that you were just doing exactly what you think, cutting off all the leaves that were higher up in the canopy that were getting sunlight. If you think about it this way, it doesn't do the plant any good to have any leaves below the canopy where they can't get any sunlight. I'd venture to say that within 2 days, those brown spots will be less noticeable.

thats what I was thinking but wanted to be sure before dropped it down .. wanted to consult the group first .. we are supposed to get a lot of rain so I'm gonna go ahead and do this now ..thanks for your response

It's hard for me to make a good judgement from the photo, but the spots do look highly suspicious of disease. Considering the conditions you mentioned it could very well be. My initial thought was dollar spot, but without seeing more pics you may describe the fertility of the lawn and what you have done recently, so I can get a better idea of whats going on. Which grass is affected - bermuda or fescue? If the area is pretty small and not getting any worse it may be best to just keep an eye on it and see what happens.

From the pic it looks to be common bermuda with low fertility. That and the mentioned conditions are prime time for dollar spot development. Most times its usually not much of a worry, actually the recommended treatment is to increase N fertility and it should solve the problem!

So I dropped cut down one notch and applied fert.. should be getting Rain tomorrow and Friday.. I'm just gonna sit back and see what happens.

I'm new, but I would venture to say with my experience, it's the wet causing the issues. You've got the heat and the rain, it's growing heavy in the canopy. You are scalping it, and there is some yellowing from the moisture.

I too freaked out about needing some fungicide.. Bought it, and it went away. Didn't even need to apply it. I even have 3 kids and slip and slides in the back yard and figured it was sure enough a fungus.

You should look to increase mowing frequency, and if short on N application, I would look to see if that doesn't correct it.

My next guess would be some iron to inhance the green up.

 

[BrettWayne]

My mowing frequency was twice a week.. Wednesday and Sunday like clock work but rain made me miss one and then I was out of town a few days. I'm hoping resetting HOC and applying N will do the trick ..

update after dropping my cut and apply N starting to green back up but still not grown back to original HOC. Should be there in a couple more days.
