Hi ti you all.


I laid a seeded turf lawn a month ago and have noticed in the last
week
that it has about a dozen small patches (around 4" circles) of what
looks like mildew.It also has that earthey smell that a associate
with
mildew.


I live in the South-east of England.
The lawn is East facing and only 50 square metres in size.It dosn`t
have any obvious shaded areas,though it dosn`t get a great deal of
sun
this time of the year anyway.


I never had this problem with my old lawn.(which was mainly weeds
anyway.)


Can anybody give me any ideas of the cause of this.


Might it be something else ?
-
When you say mildew, does it look like powdery mildew?

Or does it look like slime?


Cheers Steveo.

The picture looks pretty close to the problem.

Had a good look this morning and in the areas effected the grass is
yellow/brown,a bit Slimey and dead.

Any advice greatly appreciated.

Sounds like it could be dollar spot? One factor that favors dollar
spot is low nitrogen, but if it's been seeded a month ago, you should
have put down starter fertilizer, so there should be enough nitrogen.

I don;t think I would do anything at this point, except keep an eye on
it and apply some more nitrogren sooner than normal. Starter
fertilizer should be about gone in about 6 weeks from when you applied
it, so a light additional fertilization with a Fall type fertilizer
sometime soon shouldn't hurt at this time of year, as the even worse
diseases which could be fueled by nitrogen are not active at lower
temps. And with declining temps, if you get below 50, even the dollar
spot, if that's what it is, should go away.

Another factor is watering. DS and most other fungus diseases are
favored by wet grass. You have no choice when seeding, but going
into month 2, you should be cutting back the watering to less
frequent, more depth, and not leaving it wet at night.
