The science behind dry patches in lawns
The facts about poor
Dry patch truly is a natural soil science problem which is poorly understood.
It’s caused primarily by multi soil fungi and their mycelium growing in the lawn thatch layer and interacting with the other soil organic matter, the soil roots and the soil particles. The fungi are not pathogenic towards the individual grass plants and they do naturally work hard in breaking down thatch in the root zone. This association between fungi and thatch and soil has occured in lawns and sports turf for hundreds of years.
The active fungi’s waste product (their feaces) is a waxy substance that is able to coat the individual soil particles thus preventing these soil particles from naturally attracting available soil water.
New and old lawns suffer equally.
Dry patch can occur on slopes, under trees, on mounds, along fence and building lines, exposed sites, especially by the sea side, where the mower has scalped the lawn, in dog, cat and fox urine burn circles, fertiliser and chemical spills, petrol spills, where there is debris under the lawn, over drainage lines, where irrigation or rainfall cannot reach, leading up to, during and after droughts and on neglected lawns, the list goes on.
If you water these areas or after rainfall, the dry patches will not get wet and a simple search with a penknife, cutting a 3cm cube from the surface of the lawn following rainfall or irrigation will quickly highlight a dry, musty and moisture free cube of soil. Compare with a green area immediately alongside a dry patch area. You will quickly note the difference between the two extracted cube plugs / profiles and confirm that dry patch is present and it requires curing.
You need to cure the problem and get these dry areas wet again so that the soil particles can then naturally absorb water to support new turf grasses
Once the problem has been cured, the dry patch may return to these historic dry areas.
Prevention is better than cure
Only once these patches are moist to a depth will they support over seeding, germination and establishment of newly sown turf grasses
