Question
I have noticed that there are a lot of brown spots and dead areas in my yard. I have the sprinklers running every day since I thought that it was dry. I have noticed that the spots are only in the sunny area of my yard but not under the trees that have shade. I do not know exactly what type of grass I have since it was resodded 3 years ago because of a chemical mix error. I do not have a picture of my yard to include. I can take some pictures and e-mail them to you to help diagnose what I am obviously doing wrong. I also wanted to mention that I use the Scott's grass seeding system.

Answer
Unless you have a photo of your Grass flowering, it is simply not possible to REALLY know with GOOD ACCURACY what you have and what's wrong from a photo.  That's the plain and honest truth, no matter what anyone tells you.

However, your description gives me a lot of work with, and I have a theory.  Better than NO theory, but perhaps you can reflect on it and comment further to support or contradict....

I'd like to know if what you refer to as the Scotts 'grass seeding system' involves use of Scotts fertilizer or other product, and not just their Grass Seed or equipment.  Please advise.  And also please clarify what you mean by a 'chemical mix error' -- fertilizer was too strong and some was damaged, then overseeded with something different from the original Seed?

That said, here's what it sounds like to me.

You have a perfectly legit mix of Sun and Shade-tolerant Grasses.  The Shade Grass is doing well.  You say you are watering daily, but perhaps you are not watering the Shade Grass as much as the Sun areas, which are prone to drying out more.

Whatever.

The Grass in the Shade is different Grass from the Sun.  Fescue is likely.

The Grass in the Sun however is a Fungus-prone variety, and you are giving the Fungus a head start by watering daily, making sure the Fungus spores are taken care of and the Fungi that sprout from them is living it up like there's no tomorrow.  But only the Sun-area Grass.  Because the Shady-area Grass is resistant to Fungus.

The dead areas should be over-seeded and you should STOP fertilizing your Grass.  It's pushing -- not BOOSTING, mind you, but pushing -- cell growth beyond what is healthy, beyond what the root system can support, beyond what it would normally grow.  The leaf tissue produced is susceptible to Fungus on a plant that is already highly vulnerable.

Could be Rye.  Could be Bluegrass.  Could even be a Fescue.  It's just different from the Grass in the Shade.  Get a mild, ORGANIC fertilizer and build up your Soil.  Better yet, overseed, and then topdress with Humus, Compost or well aged Manure right away.  If you live in the right place at the right time, you can do this now; otherwise, wait 'til Spring.

Do not use a Fungicide for this problem.  It's caused by faulty watering and loss of competing Fungi that keep the pathogens in control.  Fungicide will only make it worse.

That's my theory.  Any thoughts?  rsvp
