are building on an excavated site, resulting in solid clay for my
gardens. We realise we will have to bring in topsoil, but what else
can we do to hasten the clay breakdown?
in a new garden on an excavated site is always a challenge. Make
sure you get in clean fill or topsoil. There is nothing worse than
finding out in spring that you have a host of new weeds to contend
It may pay to wait for
a couple of weeks after putting down the new topsoil before you
sow a lawn. This way you can spray or pull out weeds without disturbing
your new lawn.
If you want to break
down clay, then you can use either Yates Claybuster or Liquid Claybreaker.
The Claybuster is a compost-based product to dig into your soil.
The Claybreaker is a hose-on product that you spray on to the ground
to help break down the clay. You can also use gypsum and lots of
compost to improve your soil.
