After prolonged dry periods lawns can become susceptible Dry Patch. The condition causes the soil in the lawn to become coated in a waxy substance therefore causing it to become water repellent. Once this occurs and the soil becomes hydrophobic, it is very difficult to rehydrate and often the problem is not even remedied after substantial periods of rain fall.
Symptoms of Dry Patch are the appearance of darker rings on the lawn. The soil underneath these darker areas is completely dry. Once the problem occurs, it can be difficult to treat. With the correct care however, this condition can be easily prevented.
Regular watering is essential. Water at cooler times of the day, either early morning or late evening, to prevent evaporation and essential moisture being lost. A light sprinkling everyday is far less beneficial than a deep soaking two or three times a week. This will allow water to reach deeper into the roots of the lawn.
If however Dry Patch has already occurred, this can be remedied by applying a treatment to encourage the lawn to take on moisture once more. It will reduce the amount of water lost on the surface and encourage the water to move to the root zone where the water is most needed. If the Dry Patch is severe, the treatment may need to be repeated.
The majority of lawns will benefit from aeration. If there are no signs of Dry Patch, it will help irrigate your lawn, allowing it to take on more moisture. It will also help remedy the problem if Dry Patch has already occurred, allowing the treatment to work more effectively and encourage water to move more swiftly to the root zone.
