Look familiar? Those brownish-red patches infesting lawns all around the Terrace and elsewhere are caused by something scientists and lawn care specialists call "red thread."
It won't ruin the lawns, except esthetically. A shot of high-nitrogen fertilizer will allow the grass to reclaim itself because the disease is only in the upper part of the blades, not at the roots. We're checking with our lawn service about that.
The cause? Big surprise. An excess of rain and some unseasonably cool temperatures.
The Plant Disease Diagnostic Clinic at Cornell University advises lawn owners to avoid overwatering, especially in the late afternoon or evening. So, it makes sense to turn off those automatic sprinklers until the problem is resolved.
