Worms In Lawn

Everyone has told me that worms in lawns are a good thing. Unfortunately for me it seems to be a problem. I seem to have so  many that nearly 50% of the lawn appears to be dirt areas where the worms have been and left their mark.

This has been the case for two years now and appears in about half of my lawn (which is mostly in the sun).

The lawn is newely laid turk two years ago.

I would post a photo so you could see. It has always looked very bad. As mentioned before, neatly 50% represents dirt mounds.

I cut the grass yesterday and the dirt was considerable from the top of the grass when mowing from where the worms have been.

Any advice or comments would be welcome.

    My goodness gracious!  You cut the lawn.  What sort of a balmy place do you live in where the grass is growing?  Where I am the fields are totally bare and nothing, but nothing is growing.

    The old-fashioned method of getting rid of worm casts used to be to sweep them off with a besom before mowing.

    Sounds to me as if you're cutting your lawn much too short at this time of year.  

    As has been said, use a besom to brush the worm casts away.  Give the lawn a good raking with a spring-tine rake, aerate it all over with a fork and give it a spring dressing of a proprietory spring lawn fertiliser, or if you prefer you can use chicken pellets and water them in well.

    Then raise the cutter on your mower and have a look here scroll down for information on cutter heights.  

    And be grateful for your worms - you'd have a much worse lawn without them image

  • Thank you Dovefromabove for your reply.

    Sorry for not thanking earlier. Unfortunately I have been away unexpectedly with no internet access.

    I have brushed the worm casts away, raked and also used a scarifier. My mower has five height settings and I use the second highest, so I hope that would be ok.

    I have also since contacted a local company that specialises in lawn maintenance. They have said they have never seen anything in over 20 years that is as bad as mine and could appreciate my concern. I guess you have to see it to believe how bad it is. They have made the same recommendations as you and also suggested trying some fertiliser. So thanks you for your advice on this. Fingers crossed.

    Search your garden centre shelves for a new product I say in the Gardening Which magazine in March 2013 called CastClear.  It's not pesticide and they stated that it gave their trials 17 days worm cast free lawns.

    maybe a bit left field but how about a bird table? If there are too many worms then they can't be getting eaten by the local wildlife encourage the local birds and perhaps they will work on your problem.

  • As an update. Andy, thanks for the suggestion on Cast Clear. It was a search to get hold of, but just over two weeks ago, the problem is resolved.

    I was also told by the local Borough council who I ran into on an gardening open day to feed witha fertilizer and then leave cuttings on the lawn for about four mowings. I have not tried this as Cast Clear has solved the problem.

    If Cast Clear is not a pesticide, what is it?

  • provides alot of information, including technical, on the product. Hope this helps.
