Lawn Care - Lawn Damage by Disease, Insects, Drought, Heat, and Stress

Every summer in Sydney, Australia we can look send to our fair share of hot weather with wet and dry periods depending on local prevailing conditions.

It goes without saying that all Australian lawns and turf grasses (warm season grasses together with couch, kikuyu, buffalo, zoysia and so on) will suffer from diseases (fungal attacks), insect damage and heat stress depending on the prevailing Summer conditions.

Damage History

Generally, if the conditions are more wet, we will see more lawns damaged by fungal attacks. Obviously, there will be a greater incidence of fungal attacks with conducive conditions - those being warm and wet weather conditions.

On the other hand, if conditions are hot and dry (that is, when there has been petite heavy rain fall for several weeks), then any lawn insect damage that has already occurred will become determined with dead patches appearing in the lawn.

We observation that if we have a hot summer with regular rain fall (that is, with around 15-25 millimetres rain falling say every 7 to 10 days) then even though the insects (curl grubs, for example) have damaged the turf grass root system, this is not apparent on top - that is, the turf grass will look undamaged to the untrained eye.

With these wetter conditions, however, there is a greater chance of lawns suffering from one of many fungal diseases that assault the many dissimilar turf grasses.

Just a quick note regarding heat or drought stress to lawns.

We advise habitancy supply heavy but infrequent water to their lawns and turf grasses. Heavy but infrequent watering (25mm of rainfall or watering) promotes deep root growth. Deep root systems make lawns drought tolerant. This heavy but infrequent watering (as experienced in the coastal areas of Australia) comes in the form of our rainfall. So it stands to presuppose that we don't need to water our lawns.
