Hi all, maybe someone can help? I've googled for similar threads in
the past but can't find anything so apologies if this is a regular
question.

I've just done the first cut of the year and there's a lot of green
slime in one part of the grass. It doesn't smell, is very slippery
and seems to be like a coating on the ground. I only noticed it
because it oozed up when the wheels of the mower passed or where my
feet had been. It covers an area of about 5m x 2m and is on a high
spot so I don't think that there's a drainage problem.

The grass was originally turf over sand when the house was built about
twelve years ago, has never been in particularly great condition, gets
a "feed and weed" dressing every other year and hasn't ever had green
slime before.

Anyone any idea what it is and how I get rid of it? If a picture
would help, let me know where to post it.

Thanks for any help,
Bill.

Hi Bill,

According to Hessayon Lawn Expert:
Green and black slime is sometimes found as a coating on the turf. This
slime is made up of countless microscopic plants (blue-green algae) and is a
feature of a bare or sparsely-grassed surface coupled with waterlogged
conditions...you also find it in turf on heavy soil which has been
overrolled, underfed and cut too closely. It also attacks newly-seeded areas
on badly drained soil.

Avoiding and curing the problem
Water the affected area with Bio Moss Killer (I think that Bio is a PBI
product as are the Hessayon books - so you may find that another moss killer
works just as effectively). Routine treatment with lawn sand will also kill
algae. The slime will return unless you can correct the basic cause. This
calls for spiking and top dressing the compacted turf in autumn.

HTH
