Another mould that affects lawns is snow mould – also known as Fusarium patch – which is common after snow thaw (hence its name). You might first notice it as small patches of yellowish, dying grass that later turn brown.

Although it's less common in summer, wetter weather mixed with heat means it can appear at any time of the year. Turf constantly damp or in the shade is more likely to develop snow mould. Other exacerbating factors include poor drainage or clay soil as the lawn cannot fully dry out.

As well as trimming back large bushes, shrubs or trees that keep your lawn in the shade or block airflow, it's also a good idea to scarify your lawn, with a rake or lawnmower. Scarifying is 'scratching' the grass to remove any build-up of dense patches that can't 'breathe'. You can also aerate your lawn with a garden fork or specialist tool.
