organic matter on which the worms feeds can be as deep as two feet .
Casting
worms are a pest to lawns and sports turf surfaces therefore preventatives
need to be used to control casting worms . Years ago Sydane was used which
just killed everything in the ground which is rightly why it has now been
banned . Unfortunately the preventatives are more costly and have to be
applied every three to four months for casting worms and every year for
leatherjacket control.
Of course the other way is to add lime to your soil to change the PH which
will also deter the worms but this is not suitable for sand based fescue
grasses.
Hope this helps and doesnt confuse you further Kay



Its amazing that uninformed people still go on about earthworms
being a pest. It's been over 100 years since Darwin published his work
on earthworms and the formation of vegetable mould. Since you probably
won't have access to his work or any of the numerous papers that support
his findings I will summarise.
