have large areas (up to 2 sqm) of lawn being dug up I assume by
birds. Initially our young border collie was getting the blame but
the scratching is too superficial just enough to kill the
grass. We have several patches (7 or 8) on our large lawn and they
are unsightly and as we live in a cold winter climate (near Ruapehu)
there will be very little growth. Is there anything we can do to
prevent the birds from ruining the lawn (other than scarecrows!!)?
can I get rid and/or stop blackbirds from picking at my grass and
problem is likely to be grass grub. In February/March they feed
close to the surface of the lawn causing the dead patches you describe.
The birds are looking for grubs.
Diazinon or Soil Insect
Killer controls grass grub in lawns and is best applied before heavy
rain. It remains within the soil for up to two weeks which is usually
long enough to control the grub. Once the grass grub are under control,
the birds should stop digging.
Unfortunately, you will
need to wait until the ground temperature warms up in spring to
resow the bare patches. A cat is a good deterrent.
