Turf and Diseases

Turf diseases are a very specialised subject and what follows is intended as a quick overview.

Like all specialised subjects every expert (real or self proclaimed!) has a theory or two.  We keep ourselves abreast of the current best practise in this area mainly through our membership of The Institute of Groundsmanship


Turf Diseases

Though not found very often in domestic lawns, there are a number of diseases which can afflict grasses in the UK.  The vast majority of these are fungal and will be active (harmful to grass) in times of high humidity.  Some turf diseases are encouraged by poor fertiliser regimes, for example “Fusarium Patch” is most likely to appear on a lawn receiving excessive doses of Nitrogen (N).  But generally if the disease is entering the grass through the sword it can be treated with an anti-fungal agent.  The list of diseases falling into this category include :-

  • Fusarium
  • Red Thread
  • Dollar Spot
  • Snow Mould
  • Leaf Spot

When the disease (or fungal infection)  is in the soil, and creating an environment in which the grass in unable to live healthily, as is the case with “fairy Rings” and “Take All Patch” the provision of effective treatment is not always possible.  We may be able to alleviate some problems with a combination of Aeration, anti-fungal and wetting agents but this is an imprecise science.  In situations where grass condition is paramount and money plentiful (such as a golf green) the soil itself is usually dug out to a substantial depth, replaced and grass re-sown.  This is not something we have yet found to be required on a domestic lawn.


Mushrooms and Toadstools

These types of fungi appear from time to time on most lawns to some degree.  They are not harmful to grass and normally only present for very short periods of time.  We do not recommend that any form of treatment be applied to them.  If they do concern you, the best way to minimise their recurrence is to carefully remove them by hand, thus reducing the number of fresh spores / pathogens that they are able to distribute.
