Sparce and yellow sounds like poor drainage. This is not the time of
year to remedy. If you get a few dry days you could try lightly
brushing the worm casts (if that's what the clods are) to disperse
them.
I think you need to do the old fork and wiggle regime all over the lawn
in March/April and brush in some sharp sand to improve drainage. Then
sprinkle on some lawn feed and leave for about a month. Then re-sow
any thin patches.


wouldnt use sharp sand unless ur soil is sand based as u will create a root
break.
Brush or rake the worm casts off before cutting . Sounds like u need a good
spike on the lawn then a feed or a dose of iron will help regain the
greeness of the grass.
If the worms are a problem apply some lime to deter the worms or ask ur
local golf/bowling greenkeeper if he can spray fungicide which is also a
worm deterent.
