Dollar stains - not as pretty as it sounds

So-called "dollar spots" (lat. Sclerotinia homoeocarpa) are caused by high levels of stress on the lawn, e.g. due to drought and a lack of nutrients. They occur in summer with high temperatures during the day between 20 and 30 °C and cool nights. Nitrogen and potassium deficiency also favor the disease. Fesctuca rubra and Poa annuaare particularly susceptible.

Attention: This lawn disease is caused by spores that are spread on the lawn by people and animals. This causes the disease to spread quickly;

How do you recognize dollar stains?

Dollar spots appear as light-colored, straw-like patches that can become larger over time. A white fungal network can sometimes be seen in high humidity.

You can prevent dollar spots by keeping the soil permeable by scarifying and aerating. Our Turbogreen lawn aerator helps here. Drought stress should be kept to a minimum by watering correctly, preferably in the morning. And, as always, fertilize regularly and in a balanced way.
