Hi All

Last year a layed a new lawn in my front garden (UK) with ex quality
turf, the problem is *i layed it onto a thin layer topsoil and clay
beneath.

It does not respond much to feeding and it soggy winter/cracks up in
summer.

I have just started spring maintenance and have cut it back short and
scarified so it now looks very sparse/muddy.

I have also just aerated it leaving holes all over.

How can i improve the soil structure ? Some people telling me brushing
in sharp sand will make it worse !!

Any ides peeps ? What about claybreaker soil conditioner or calcified
seaweed ??

Cheers

You've created a big problem with no easy solution. You should have
worked on fixing the soil BEFORE putting down the new turf. The less
good topsoil you have, the more problems you will have. By doing it
before the grass, you could have tilled in lots of material or
additonal topsoil to correct it. Now, your ability to deal with it
is limited.

The best you can do now is to rake in material after aerating. The
choice of what to use is usually determined by what's available
locally in appropriate quantities and cost. If it's a small area,
then a commercially bagged product could be viable. But for larger
areas, you generally need something available by the truck load.

My first choice would be organic matter, like compost. Here in the
states some municipalities collect leaves in the Fall and turn them
into compost which is available for free. If you have anything like
that available, it can be a good choice. You can also mix in some
sand, but I would focus more on the compost type material.
Unfortunately, you will have to do this many times before you get the
soil to where you want it. And even then, the depth of the ammendment
is not as deep as it would be had you tilled it in upfront.
