How to get rid of worms in lawns

Willy the Worm - CastClearLawn worm casts are a bit of a pain  at this time of the year until late spring.  The worms eat the soil and then discard it on the lawns surface leaving it there for the dog to pick up the small mound of soil on their paws or on your shoes when you walk over the lawn.  The title of this blog post was a typical Google search.  The worms are great for the lawn, but their messy soil casts are not.

There are just five types of worms in the UK that throw up what turf professionals call a lawn worm cast.  The worms spend the drier months burrowing deeper in the soil, eating the organic matter in the soil, extracting it's goodness. 

A family of worms are responsible for turing over an incredible amount of soil per annum, a bit like pigs in a new grass field, providing vital aeration holes, beneficial for all the vegetation growing in the soil, like a lawn for example.

As the soil air to water ratio changes in the more traditional autumn months, you will notice an increase in worm cast activity.  The wetter the autumn or winter, the greater the worm activity will be. The root zone of the lawn will become spongy as the worms undermine the upper surface and mowing will become difficult, especially with a cylinder mower. The use of the lawn will diminish as a result of the difficult surface conditions.

It is not the activity of the worms naturally aerating the soil beneath the grass surface, but the detrimental effect of their casts that cause the problems. The soil making up the casts is very slimy as it consists of soil and the natural secretions from the worm’s digestive system. Left on the surface of the lawn, the casts will be smeared across the grass through the actions of mowing and walking on the lawn.

The end result is that worms are capable of pushing up an incredible volume of soil by way of their casts so it does not take long for the surface of the lawn to become really muddy and slippery. Over time the worm casts smear the grasses and you end up with no lawn, muddy platform shoes, muddy paw prints from the dog coming back into the kitchen and muddy children. 

An application of a non pesticide control product called CastClear will greatly prolong the use of the lawn in the autumn to spring months and protect the existing surface of the lawn so that you might end up with grass cover in the spring.  The overall micro levels of the lawn will instantly be improved.

It's available from The Lawn Company via their online Lawn Shop and at Garden Centre Stockists. 

If you are a Garden Centre or Garden Retail Outlet and want to stock CastClear or require a sample label, email The Lawn Company Team
