Turf mould

The appearance of mould on turf is very common at this time of year, and can be quite alarming. Read on to find out how to deal with turf mould with expert advice from Essex turf grower and supplier, Paynes Turf.

Turf mould

Fungus is present in all turf, whether newly laid or in an established garden, and becomes active during moist, warm weather. From the beginning of November until the start of spring it’s common for mould to develop on turf. Some of the reasons for this are:

  • More rainfall
  • Overnight temperatures that are milder than usual for the time of year
  • The presence of morning dew

Around this time of year, the growth of grass slows down dramatically. The reduction in growth, coupled with morning dew that becomes stagnant, warmer temperatures, and overall wetter weather could cause the fungus already present in the turf to grow.

Early morning dew could remain on grass all day long given the right conditions. This will encourage the growth of mould.

Mould in newly laid turf

The process of harvesting turf causes stress to the turf, and it’s in this vulnerable state that the fungus laying dormant in the turf begins to attack the grass plants. However, once newly laid turf is established, it will become stronger and better able to fight off the fungal attack.

This is why care should be taken when laying new turf; excessive handling of the turf both before and after it’s laid can encourage the fungus present in the turf to grow. To help prevent this from happening, make sure that you don’t walk on the turf any more than is necessary (and always use a board to walk on), plus don’t mow the new turf until it has established. If mould does begin to grow on your new turf, it should soon disappear as the turf establishes and gets stronger.

Always use a board to walk on when laying turf

As the colder winter weather approaches and the temperatures drop below freezing, any turf mould present in the turf will disappear. If the temperatures do not drop to a sufficient level to destroy the mould, wait until spring when rapid grass growth and higher light levels will cause the mould to recede.

Always remember to choose a reputable turf grower when choosing your turf to be sure that only the best disease resistant cultivars are used.
