    Being in the business (1st year) its a little embarassing that my lawn looks like the pits,

    question1 pic 1 (dsco2552) pic 2 (dsco 2555) is this lawn disease? or what is the problem?

    question 2 pic 3 (dsco 2556) this was newly seeded grass (mix of p rye and k blue) in the spring that looked awesome in early june, what happened ? we had a wet summer but a very dry sept, will it come back?

    question3 Ive sprayed creeping charlie atleast 5 times with a gammot of things, ive noticed ive burned holes in the leaf, is this normal, should I not even bother spraying k charle until its November its so resilant it doesnt die .

    Don't know what your rain has been like this season but suggest looking for active grubs in the soil.

    Looks very dry, especially under the cedar tree in the 3rd pic. Supposed to get an inch of rain tonite into tomorrow, a nice soaker, should help.

    Looks like the lawn is dried out bud. No insect/disease probs IMO. Guessing from the pics, it's mostly KBG & a little rye. We prefer KBG cuz it spreads, but it needs water to do so - especially under trees cuz when it rains, most of the water sheds out to the dripline instead of under the tree (pic #3).

    Pic #1) I see acorns. Pic #2) I see oak leaves. Pic #3) The tree trunk looks really bad -- guessing this tree is on it's way out.

    Bottom line - judging from your pictures, the grass looks dormant -- not dead. If I'm right, water a.s.a.p. thoroughly. Maybe some fert too.

    Anybody else? :confused:

    Look at pic 3. Like Larry said, it is dry under that tree. But I believe, it is due to tree roots competiton for the water with the grass roots. Common in late summer. We call this "root burn". It appears as a brown dry spot on the south side of a tree. It is worst where the roots reach out farther than the shade of the branches.

    What is the white fuzzy stuff in the foreground? Fuzzy pic or is that fungus?

    I am glad to see you at least OWN a hose. What are you using it for?

    Gotcha, That totally makes sense. The grass is dried out due to competition for water from tree, will this lawn come back? Another question? I understand that pic 1 looks like my lawn is dormant but why are other sections as green as could be, also would it be normal for my lawn to go into dormancy in late sept, its been warm 70s 80s during the day and a bit cooler 50's at night.

    Looking at the first pic, it looks light a severe case of tip blight that has bleached out. If you look close, you can see a couple of blades are green half way up from the crown, with the top half bleached (blighted).

    With this being a newly seeded lawn, it is unlikely that the root system would have been more than a couple of inches in depth. Most cool season grasses take a good year to reach the 6-8" depth so as to be called "established".

    If that is an Oak tree, they will suck up every last drop of moisture present. Tough to keep established lawns going, let alone new ones.

    The last pic with the all the poc marks looks to be from something scratching at the surface for insects. Could be grubs. Is the turf somewhat spongy feeling, and lifts up like a rug? Very easy to check for them.

    Alot of rain in my area, and I started seeing grub activity 3 weeks ago.

    Good luck

    Dormancy is a function of dryness. Cool temps at night will not help-nor will a heavy dew. Areas shaded by a garage or the east and north sides of a tree are protected from the heat of the sun. These areas will remain green longer--the soil is almost as dry as the sunny areas. Better--more drought resistant seed would help. Areas of tougher grass, like tall fescue will hold their color longer. Stick a screwdriver in as far as you can. One inch--too dry. 3 inches--adequate. 5 inches--wet.

    That last photographs has what looks like a Red Cedar from the bark and root system. Nothing will grow under them. They are only second from Magnolia to acidify the ground.
    Even their needles and off fallings will kill grass. Over the last bunch of years, I found nothing that will neutralize Red Cedar turf. If it is not a cedar, what kind of tree do you have or photograph it with some folliage.

    brown (dormant) grass is your friend. No input needed and it will come back. Save $ on water, fert, mowing, etc. Green is over-rated in some cases.
