Watch out for earthworms on sports pitches

At this time earthworm casts can develop over much of the pitch.   The main concern is the muddy condition that results after mowing.  If sand dressing has been applied a clay soil brought to the surface also dilutes the dressing and impairs the benefits of the sand layer on the pitch surface.  Timely spraying temporarily stops the development of the casts before the cold weather further restricts earthworm activity on the surface.
