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?
